Key Takeaways

  • Full-Stack vs. Serverless: Simplismart covers fine-tuning through deployment; Modal is Python-native serverless GPU compute, no YAML, no Kubernetes.
  • Deployment & Sovereignty: Simplismart runs anywhere, BYOC, on-prem, air-gapped; Modal is managed-cloud only, no exceptions.
  • Multimodal vs. Developer-First: Simplismart ships ready-to-call pipelines for text, speech, image, and video; Modal supports all modalities, but you assemble the stack yourself.
  • Speed Engines: Simplismart uses proprietary Megakernels and hybrid parallelism; Modal uses SGLang, DFlash speculative decoding, and sub-1s cold starts.
  • Cost Model: Modal's scale-to-zero per-second billing wins for bursty workloads; Simplismart's BYOC pricing and broader GPU menu win for sustained or owned-infrastructure workloads.
  • Compliance & SLA: Simplismart, ISO 27001, SOC 2 Type II, 99.9% SLA, air-gapped; Modal, SOC 2 Type II, HIPAA on Enterprise, no published SLA, no on-prem.

Choosing between Simplismart and Modal? This comparison breaks down pricing, deployment options, performance, and compliance so you can decide in under 5 minutes. 

As open-weight models have matured, many teams have discovered that deployment and operations are often harder than model selection itself. Open-weight models are strong enough that the real differentiator is now how you serve them, cost per token, tail latency, where data lives, governance, and how much of the stack you control.

Developer-first teams wanting Python-native serverless GPU infra with fast iteration and scale-to-zero economics 

Simplismart and Modal both promise faster, cheaper inference than a do-it-yourself stack on vLLM or TensorRT-LLM, but they were built around fundamentally different philosophies. Modal leads with a Python-native, code-first developer experience; you decorate a function, specify a GPU, and Modal handles containers, scaling, and billing, with per-second costs that drop to zero when idle. Simplismart leads with a platform that adapts to where your models need to run: shared APIs, your own Kubernetes, your cloud account, or your own data centre, paired with end-to-end MLOps from fine-tuning through production serving. This comparison draws on each vendor's product, pricing, security, and engineering documentation; every benchmark is attributed, since inference performance is always workload-dependent. 

What Is Simplismart? AI Inference Platform Overview

Simplismart is an AI inference platform built to deploy, serve, and optimise AI models across multiple environments, from shared cloud APIs to fully private infrastructure. Its positioning, "inference that adapts to your needs," reflects the architecture: run models wherever your constraints demand without sacrificing operational efficiency. Operated by Verute Technologies and built as an orchestration layer over NVIDIA GPU infrastructure, it pairs a proprietary inference engine with end-to-end MLOps like fine-tuning LLMs, deployment, autoscaling, and observability in one platform.

Two Primary Deployment Modes:

  • Shared Endpoints - immediate, pay-as-you-go access to 150+ pre-deployed open-source models spanning LLMs (Llama, Mistral, DeepSeek, Qwen, Gemma, Phi), vision-language models, diffusion models (Flux, SDXL), and speech models (Whisper). Purpose-built for evaluating models, building prototypes, or running lower-volume inference with no infrastructure to manage.
  • Dedicated Endpoints - deploy any model (open-source, custom, or fine-tuned) on your own Kubernetes infrastructure or on Simplismart-managed GPUs. The production-grade path, with full control over resources, scaling behaviour, and deployment configuration.

What separates Simplismart from simpler managed services is its BYOC (Bring Your Own Cloud) and on-premises capability. Connect an AWS, Azure, or GCP account, and Simplismart provisions and manages the entire Kubernetes cluster inside it. Or import an existing cluster via kubeconfig. That keeps the cluster lifecycle in your hands while you delegate workload orchestration to Simplismart.

Simplismart is also an early NVIDIA Inception member and an NVIDIA Cloud Partner. It offers its optimized stack to providers as a white-labeled solution.

What Is Modal? Features, Products and How It Works

Modal is a Python-native serverless GPU cloud built for AI and ML teams who want to ship inference, training, and batch workloads without managing infrastructure. Founded by Erik Bernhardsson and Akshat Bubna in New York City, the company reached unicorn status with a $1.1 billion valuation in September 2025. Its core philosophy is infrastructure-as-code: rather than configuring clusters or writing YAML, you define hardware requirements directly in your Python application code using Modal's SDK, and the platform handles everything from container builds to GPU provisioning to autoscaling. 

Ships Four Core Products:

  • Inference (Auto Endpoints) - OpenAI API-compatible, production-ready inference services backed by Modal Apps that you can see and control, with full visibility into GPU selection, engine flags, speculative decoding metrics, and per-replica token latency. 
  • Training - Distributed fine-tuning on per-second billed GPUs using any framework, including LoRA, Unsloth, and PyTorch, on single or multi-node clusters.
  • Batch Processing - Parallel jobs across thousands of GPUs with no job orchestration to manage. 
  • Sandboxes: Ephemeral, isolated containers for running untrusted code, evals, and agent environments.

Modal serves AI-native startups and established platforms, with named customers including Suno (audio AI), Substack, OpenArt, and Lovable. Any model from Hugging Face can be loaded into a Modal container, and its Auto Endpoints catalogue covers popular open-weight families out of the box. Modal is managed-only - there is no BYOC, on-premises, or air-gapped deployment option. 

The core difference: Modal is a developer-first serverless GPU cloud optimized for fast iteration and scale-to-zero economics; Simplismart is an end-to-end platform that fine-tunes, serves, and optimizes across a much wider range of environments - from shared APIs to air-gapped data centers - with first-class support for language, speech, diffusion, and video workloads.

Simplismart vs Modal: Deployment Options Compared

Deployment model is the highest-leverage decision here because it sets where your data lives, how predictable your costs are, and how much of the stack your team owns.

Simplismart's Deployment Range

Simplismart is designed to meet teams across the full spectrum, from zero-ops APIs to sovereign infrastructure:

  • Shared Endpoints for instant, managed access with nothing to provision.
  • Dedicated Endpoints on Simplismart-managed GPUs, or on your own cluster.
  • BYOC, where Simplismart provisions and manages a full Kubernetes cluster inside your AWS, Azure, or GCP account, or adopts an existing cluster via kubeconfig.
  • On-premises and air-gapped deployments for regulated environments, with physical GPU custody and zero data exposure.

The unifying idea is a single control plane that orchestrates models, tooling, and hardware while keeping data inside your perimeter wherever required.

Modal's Deployment Options

Modal is serverless and managed by design - infrastructure lives in your Python code, not in a control plane you configure:

  • Serverless containers that instantly autoscale up and down based on request volume, with cold start times typically between 2–4 seconds. 
  • Non-preemptible execution for workloads that cannot be interrupted, available at a 3x price premium over base rates.  
  • Region selection for latency or compliance reasons, though specific region deployment adds a 1.25x–1.75x cost multiplier. 
  • No BYOC, no on-premises, and no air-gapped option - Modal is managed-only. 

Bottom line: these two platforms sit at opposite ends of the deployment spectrum. Simplismart treats the full path - shared, dedicated, BYOC, on-prem, air-gapped - as first-class, actively provisioning and managing infrastructure inside your own account rather than handing you a container to operate. Modal deliberately offers none of that: it is not suitable for enterprises with strict VPC or BYOC requirements, and there is no path to physical GPU custody. If infrastructure flexibility and data sovereignty drive the decision, Simplismart is the only platform that covers every scenario. If your team never wants to think about infrastructure at all and is comfortable running entirely on Modal's managed cloud, Modal's Python-native model is among the cleanest developer experiences available.  

Multimodal AI Inference Support: Which Platform Covers More?

 

Supported Models

Both platforms cover the major open-weight families, Llama, Qwen, DeepSeek, Mistral, Gemma, Phi, plus custom and fine-tuned weights. Modal supports any model from Hugging Face loaded into a container, and its Auto Endpoints catalogue covers popular open-weight families out of the box for one-command deployment. Simplismart curates 150+ production-ready models on Shared Endpoints and lets teams import any custom model for Dedicated, BYOC, or on-prem deployment. For mainstream text models, availability isn't the differentiator; the divergence appears beyond text. 

Multimodal Coverage

Modal is not text-only; its inference platform supports LLMs, image generation, video, audio, and embeddings, and can run any model or inference engine on H100s, A100s, A10Gs and more. However, Modal's multimodal support is largely bring-your-own  , you assemble the stack yourself using its container primitives and example library. Where Simplismart pulls ahead is in production-ready, deeply optimized coverage across generative modalities  , language, vision, diffusion, and speech  , with pre-deployed models you can call today, without assembling a custom container pipeline.

Video generation supported (e.g., LTX-Video, Mochi)Modal via custom containers

Why modality coverage matters: Production AI is increasingly multimodal  , agents, real-time voice assistants, live transcription, video intelligence. For a latency-critical voice agent, the bottleneck is rarely the LLM alone but the whole STT → LLM → TTS pipeline holding a consistent tail latency. The distinction here is not capability but readiness: Modal gives you the GPU primitives and example code to build any pipeline yourself, while Simplismart ships pre-deployed, optimized endpoints across modalities that teams can call immediately. For teams with the engineering bandwidth to assemble and tune their own multimodal stack, Modal's flexibility is sufficient. For teams that need production-ready diffusion, speech, and video endpoints out of the box without that overhead, Simplismart carries the clear edge. 

Inference Optimization: How Each Platform Squeezes More Out of Every GPU 

Both platforms do serious systems engineering to extract more tokens per GPU; their emphasis differs by layer.

How Simplismart Optimizes Inference

Simplismart's stack centers on two signature techniques.

The first is Megakernels. A megakernel fuses an entire forward pass into a single GPU kernel, rather than hundreds of small CUDA kernels that leave the GPU idle between launches. The approach builds on Stanford research by Spector, Juravsky, et al. Simplismart reports a sub-1 ms Llama-1B forward pass on an H100, with far higher bandwidth utilization.

The second is hybrid parallelism. It combines tensor, sequence (Ulysses with Ring attention), pipeline, and expert parallelism for very large and long-sequence models. On Wan-class video diffusion, Simplismart reports a 2.65× speedup (159 s to 60 s on 8×H100). On Kimi K2 Thinking, it reports roughly 3× the throughput of baseline vLLM on 8×B200, using NVFP4 quantization with tensor and expert parallelism.

Custom CUDA kernels, quantization, continuous batching, and cache-, latency-, and prefix-aware routing complete the stack. These performance figures are vendor-reported and configuration-specific.

How Modal Optimizes Inference

Modal's optimization story centres on its Auto Endpoints product, launched in June 2026. Rather than building a proprietary serving engine from scratch, Modal bets on open-source inference engines,  primarily SGLang, and contributes optimizations upstream.

Modal's centrepiece optimisation is speculative decoding using the DFlash block-diffusion drafter architecture from Z Lab. Modal worked directly with Z Lab and the SGLang team to make DFlash fast and reliable in real serving systems, and trained and released its own DFlash drafter models to expand support and ensure optimal performance.

Crucially, Modal does not hide the stack: everything from GPU selection and regionalisation to inference engine flags is shared with the user, and metrics like speculative decoding acceptance length and per-replica, engine-side token latency quantiles are automatically surfaced in dashboards. This transparency is a deliberate differentiator against black-box managed inference providers. 

At the infrastructure layer, Modal's Rust-based container stack spins up GPUs in under 1 second, and its proprietary cloud capacity orchestrator guarantees high GPU availability. Per-second billing means idle GPU time is never charged, which is itself a form of cost optimization for bursty workloads.

The two stacks reflect their different philosophies. Modal's strengths cluster around developer transparency, open-source engine velocity, and the operational efficiency of serverless scale-to-zero. Simplismart's signature work targets maximum performance on large, multimodal, and MoE workloads, including on hardware you control directly, with proprietary kernel-level optimizations that go beyond what open-source inference engines provide out of the box. 

Simplismart vs Modal: Performance Benchmarks, Scaling, and Uptime Compared 

Performance benchmarks should be treated as reference points rather than guarantees.

Simplismart has cited 11,000 tokens/sec on Llama2-7B on A100s, and its published Llama 3.1 8B vLLM optimization guide reports total throughput scaling from 8,674 tokens/sec at baseline to 23,465 tokens/sec with tensor parallelism and INT4 quantization. 

Modal does not publish proprietary throughput benchmarks against vLLM baselines. Its catalog page claims 50%+ savings on high-throughput, short-context tasks compared to API providers, and customer case studies report latency improvements,  for example, a 3x reduction in VLM document parsing latency and a 65% latency reduction for real-time inference at Runway. These are workload-specific outcomes, not published throughput figures. Both platforms materially beat a naive open-source deployment for teams without dedicated infrastructure engineering. 

Scaling Large Models. 

Both serve 70B+ and trillion-parameter MoE:

  • Multi-GPU serving: Simplismart via tensor, pipeline, expert, and sequence parallelism; Modal via tensor parallelism through SGLang and vLLM, with multi-node cluster support available in beta. 
  • Large context: Simplismart 32K+ (megakernel-demonstrated); Modal supports long-context models via its inference engine integrations, with context limits determined by the underlying engine and GPU memory configuration.
  • Trillion-parameter MoE: Simplismart (Kimi K2 ~1T on 8×B200); Modal supports large MoE models via custom container deployment, though no specific trillion-parameter benchmarks are published.

Uptime and Autoscaling:

  • Published SLA: Simplismart publishes a 99.9% uptime SLA. Modal does not publish a formal uptime SLA, a meaningful gap for enterprise buyers who need contractual availability guarantees.
  • Autoscaling: Simplismart reports sub-60-second pod spin-up, autoscaling on latency, concurrency, and memory, and scale-to-zero on idle. Modal is serverless by design, instantly autoscaling up and down based on request volume, with a Rust-based container stack that spins up GPUs in under 1 second. 
  • Failover: Modal routes workloads across clouds and regions in real time via its proprietary capacity orchestrator. Simplismart supports redundant-node and local-failover patterns, including on-prem without internet dependency,  a capability that Modal does not offer.

Observability. Simplismart is Grafana and Prometheus native, with real-time latency, throughput, and cluster-health metrics, plus benchmarking jobs across training and inference. Modal surfaces engine-side metrics, including speculative decoding acceptance length and per-replica token latency quantiles automatically in dashboards, with integrated logging and full visibility into every function, sandbox, and container. Both platforms give production teams the observability they need; Simplismart's stack extends to on-prem and air-gapped environments where Modal's cloud-native dashboards do not reach. 

The practical caveat on SLAs: in an air-gapped or on-prem deployment, availability also depends on your own redundancy design, the trade-off teams accept for sovereignty. Modal's absence of a published SLA is a different kind of caveat: teams building revenue-critical products on Modal should factor that into their vendor risk assessment.

Simplismart vs Modal Pricing: Full Breakdown 

An important framing note upfront: these two platforms use fundamentally different billing models. Simplismart publishes per-token rates for shared endpoints and per-GPU-hour rates for dedicated infrastructure. Modal bills per second of actual GPU compute with no per-token pricing at all, making a direct apples-to-apples comparison require some translation. Both platforms publish transparent pricing at entry tier; neither is quote-only to get started.

Key pricing considerations for Modal:


Production workloads requiring guaranteed non-preemptible execution face a 3x cost multiplier, and specific region selection adds a 1.25x–1.75x multiplier to base compute costs. This means at approximately $3.95/hr, effective for H100 under sustained load, Modal is more expensive than every major dedicated GPU provider. The per-second billing advantage is most pronounced for bursty, low-utilisation workloads where scale-to-zero prevents idle charges from accumulating. 

Modal's headline GPU rates are lower than Simplismart's on paper for several tiers, but the per-second model tells only part of the story. For variable or early-stage workloads with unpredictable traffic, Modal's scale-to-zero economics are a genuine advantage  , you pay for nothing when idle. For sustained high-volume inference, multimodal workloads spanning diffusion and speech, or teams with owned infrastructure, Simplismart's model offers more levers: published per-token and per-image rates that make cost forecasting straightforward, a wider GPU menu from T4 to B200 to right-size hardware to workload, pay-as-you-go BYOC pricing that eliminates rental markup entirely, and no multipliers that inflate costs for production or region-specific deployments.

Enterprise Security, Governance & Compliance: SOC 2, HIPAA, and Beyond

Both vendors have invested in formal compliance assurance, but their certifications, deployment models, and the industries they can realistically serve differ in important ways.

  • Modal: SOC 2 Type II compliant. HIPAA-compatible workloads are supported, but a Business Associate Agreement must be established prior to any PHI submission, and this is only available on the Enterprise plan. No ISO 27001. No BYOC, on-prem, or air-gapped option  , all workloads run on Modal's managed cloud infrastructure. 
  • Simplismart: ISO 27001 and SOC 2 Type II, plus automated compliance validation for SOC 2, HIPAA, and GDPR, and policy-based access control with audit trails. Air-gapped deployment with physical GPU custody available for environments where data cannot leave the customer's perimeter.

Modal does not support VPC isolation in the traditional BYOC sense, and has no on-prem path. Simplismart supports VPC isolation, on-prem, and air-gapped deployment  , the pattern many BFSI, government, and defense buyers require when data cannot leave their environment under any circumstances.

By industry:

Healthcare and life sciences can use either platform for HIPAA workloads in principle, but the deployment model determines fit. Modal only enters into BAAs with Enterprise plan customers, and certain product areas, including Volumes v1, Memory Snapshots, and user code, remain outside the scope of BAA commitments. Teams that need PHI to stay on owned, on-prem, or air-gapped infrastructure, with token-level PHI/PII controls and physical GPU custody, require Simplismart. 

Finance (BFSI) teams with strict data-residency requirements will find Modal a hard blocker: there is no path to running workloads on owned infrastructure or in a private cloud you control. Simplismart's BYOC and air-gapped models directly address residency mandates. Teams prioritising speed-to-production on managed infrastructure without residency constraints can evaluate either.

Government and defence map almost exclusively to Simplismart. Modal's managed-only, US-cloud architecture does not meet the physical custody and network isolation requirements common in these sectors. Simplismart's sovereign, air-gapped deployment model with physical GPU custody is the pattern these buyers require.

Research and startups are the segment where Modal competes most strongly on compliance, SOC 2 Type II is typically sufficient, HIPAA on Enterprise covers healthcare-adjacent use cases, and the absence of BYOC or air-gapped is rarely a constraint for early-stage teams prioritizing iteration speed over sovereignty.

How to Choose Between Simplismart and Modal: A Decision Guide

Choose Simplismart If

  • Your roadmap is multimodal  , language, speech, diffusion, and video  , not text-only, and you need production-ready endpoints across all modalities without assembling custom container pipelines.
  • You need deployment flexibility and data sovereignty across shared APIs, your own Kubernetes, BYOC, on-prem, or air-gapped infrastructure.
  • You want an end-to-end platform that covers LLM fine-tuning (SFT, GRPO, DPO, PEFT) and serving in one place, not just inference.
  • You run steady, high-volume or owned-infrastructure workloads where a broad GPU menu and BYOC economics give you direct control over total cost.
  • You value NVIDIA-aligned optimization (megakernels, hybrid parallelism) and a single control plane that works consistently across every environment.
  • You need a published uptime SLA (99.9%) and formal compliance coverage including ISO 27001, automated HIPAA and GDPR validation, and air-gapped physical GPU custody for regulated industries.

Choose Modal If

  • You want Python-native, code-first infrastructure, no YAML, no Kubernetes, no DevOps overhead, where hardware requirements live directly in your application code.
  • Your workloads are bursty or unpredictable, and scale-to-zero economics matter more than raw per-hour GPU rates, since you only pay for active compute time.
  • You want to own your inference stack, code, engine flags, and metrics fully visible, without the operational burden of running your own container cluster.
  • You want to deploy Frontier open models with a CLI command rather than a sales process, with benchmarking results exposed before you commit to a configuration. 
  • Your team is developer-first, values fast iteration cycles, and works primarily in Python across inference, training, and batch workloads on a single platform.
  • Compliance requirements are satisfied by SOC 2 Type II and managed HIPAA on Enterprise, and your workloads do not require BYOC, on-prem, or air-gapped deployment.

Bottom line. Modal is the cleaner fit when the priority is developer experience, Python-native deployment, and scale-to-zero economics, particularly for startups, ML-native teams, and workloads with variable or unpredictable traffic patterns. Simplismart is the more adaptable platform: it meets teams from zero-ops shared APIs all the way to air-gapped data centers, serves and optimises across language, speech, diffusion, and video, adds fine-tuning and BYOC economics that a serverless GPU cloud doesn't offer, and backs it all with a published 99.9% uptime SLA. Modal has no on-prem path, no published SLA, and no BYOC option  , three hard stops for regulated enterprise buyers that Simplismart clears directly. Neither is universally better. Your deployment requirements, compliance posture, and team's infrastructure philosophy decide it.

Frequently Asked Questions

What is the main difference between Simplismart and Modal?

Modal is a Python-native serverless GPU cloud focused on developer experience, code-first infrastructure, and scale-to-zero economics for inference, training, and batch workloads. Simplismart is an end-to-end platform that fine-tunes, serves, and optimizes models across a much wider range of environments, shared APIs, your own Kubernetes, BYOC, on-premises, and air-gapped, with first-class production-ready coverage for language, speech, diffusion, and video.

Is Simplismart a good alternative to Modal?

They serve different primary use cases. Simplismart is the stronger fit for multimodal support, BYOC, on-premises, air-gapped deployment, managed fine-tuning, and enterprise compliance with a published SLA. Modal wins for Python-native developer experience, fast iteration cycles, and scale-to-zero economics on bursty or variable workloads. Organisations prioritising serverless simplicity and code-first infrastructure may prefer Modal; those requiring data sovereignty, multimodal breadth, or regulated deployment will find Simplismart the closer fit.

Which platform is better for multimodal inference, speech, image, and video?

Both support text, vision, and audio workloads. The distinction is readiness versus flexibility. Simplismart ships pre-deployed, production-optimized endpoints for diffusion models (Flux, SDXL), large video diffusion transformers, and real-time voice-agent pipelines that teams can call immediately. Modal supports image generation, video, and audio inference via its container primitives and example library, but requires teams to assemble and manage their own multimodal pipelines. If your roadmap spans several modalities and you need them production-ready out of the box, Simplismart has the clear edge. 

Can you fine-tune LLMs on these platforms, or only run inference?

Both support fine-tuning, but in very different ways. Modal supports fine-tuning via custom containers using any framework, LoRA, Unsloth, PyTorch, and others, on per-second billed GPUs, but does not provide a managed fine-tuning pipeline. Simplismart is end-to-end: it supports distributed fine-tuning (SFT, GRPO, DPO, and PEFT methods such as LoRA and QLoRA) as a managed service alongside serving, so teams can train and deploy without switching tools or assembling their own training infrastructure.

Which inference platform is better for regulated industries and data sovereignty?

Both hold SOC 2 Type II certification. Modal supports HIPAA-compatible workloads on its Enterprise plan, requiring a BAA to be signed before any PHI is submitted, with certain product areas remaining outside BAA scope. Simplismart adds ISO 27001 plus automated SOC 2, HIPAA, and GDPR validation. For strict data residency, Simplismart's air-gapped deployment with physical GPU custody is the only option between the two. Modal is managed-only with no BYOC or on-premises path, making it unsuitable for BFSI, government, and defence buyers, where data cannot leave a controlled environment.

Should I choose serverless or dedicated inference?

Use serverless endpoints for evaluation, prototyping, and variable or low-volume traffic; you pay per use with no infrastructure to manage. Move to dedicated GPUs for predictable, high-volume production that needs consistent latency and resource control. Simplismart lets you start on Shared Endpoints and graduate to Dedicated, BYOC, or on-prem as requirements grow. Modal's entire model is serverless; for workloads requiring guaranteed non-preemptible execution, a 3x price multiplier applies rather than a traditional dedicated GPU tier. 

Can I deploy Hugging Face models on both Simplismart and Modal?

Both support the major open-weight families, Llama, Qwen, DeepSeek, Mistral, Gemma, Phi, plus custom and fine-tuned weights. Modal supports loading any Hugging Face model into a container via its Volume storage, and its Auto Endpoints catalogue covers popular families for one-command deployment. Simplismart curates 150+ production-ready models on its Shared Endpoints and lets teams import any custom model for Dedicated, BYOC, or on-prem deployment. If you need the broadest possible Hugging Face catalogue with minimal setup, Modal's container-based approach covers it; if you want curated, deeply optimised models plus the freedom to bring your own across any infrastructure, Simplismart fits.

Which platform offers a higher uptime SLA?

Simplismart publishes a 99.9% uptime SLA. Modal does not publish a formal uptime SLA, a notable gap for enterprise buyers who need contractual availability guarantees. On autoscaling and failover, both are strong: Simplismart reports sub-60-second pod spin-up with scale-to-zero on idle, while Modal's Rust-based container stack spins up GPUs in under 1 second and its proprietary capacity orchestrator guarantees high GPU availability. One caveat: in an air-gapped or on-prem deployment, availability also depends on your own redundancy design, the trade-off teams accept for full data sovereignty. Modal's absence of a published SLA is a separate consideration: teams building revenue-critical products should factor vendor uptime commitments into their platform decision.
