Novita AI alternatives: 11 inference APIs to compare

Built for the startup developer calling open models by API

You've got a product idea, a model that does the job and an API key in your environment file. You don't want to host weights yourself, and you don't want to be stuck if one provider has a bad week. That's the reader I had in mind here: a small team that calls hosted open-source models through an API and wants to compare Novita AI with other inference providers.

Every provider below runs models for you. What changes is the focus. Some lead with a huge model catalogue, some with speed for agents, some with production support, and some with an energy or security angle. The questions below help you sort them.

Five questions that decide your inference provider

Does it host the exact model you use? A catalogue of hundreds of models means nothing if your chosen one isn't there, or is only there in a different size. Check the model card, not the marketing page.

Can you switch with a one-line change? Some providers describe an OpenAI-compatible API. If yours does, moving between them can be as simple as swapping a base URL and key. If it doesn't, count the time you'll spend rewriting calls.

How does it behave under load? Ask about rate limits, queueing and cold starts. A demo that answers in a blink can slow right down when a hundred users arrive at once.

What do you get when something breaks? Some providers talk about dedicated support and round-the-clock help. For a startup with paying customers, that matters as much as speed.

Where does your data go? Read how prompts and outputs are stored and whether they're used for anything else. It's a five-minute read that saves awkward conversations later.

Eleven providers, listed in no particular order

Alphabetical and in no particular order. Each line paraphrases what the vendor says on its own site, so treat it as a starting point and check the details that matter to your app.

Chutes

Best for: Developers who want serverless open-source models behind an OpenAI-compatible API, including models protected by trusted execution environments.

Cloudflare Workers AI

Best for: Apps that want to run machine learning models on serverless GPUs within the Cloudflare platform.

Crusoe

Best for: Teams that like an energy-first approach to AI infrastructure, with round-the-clock support named by the vendor.

DeepInfra

Best for: Startups after production-ready models that are easy to deploy and scale, in the vendor's own framing.

Featherless

Best for: Builders who want to deploy any open model without much setup work.

Friendli

Best for: Agent builders running frontier open-weight models in production, where output speed and uptime claims matter most.

Inference.net

Best for: AI-native teams who want to run, monitor and tune production workloads with dedicated support.

Nscale

Best for: Companies planning for scale who want a full-stack AI cloud with services around it.

Parasail

Best for: AI-native startups that want any open model with production reliability and per-token billing.

Replicate

Best for: Running open-source machine learning models through a cloud API.

SiliconFlow

Best for: Developers choosing from a large catalogue of LLMs and multimodal models, with fine-tuning and deployment behind simple APIs.

Before you swap one API key for another

Run a short pilot before you commit. Pick twenty real prompts from your logs, send them to your current provider and two alternatives, and save the answers next to each other. You'll see quickly which ones match your quality bar and which ones stumble on your edge cases.

If you're still weighing open models against a closed one, my explainer on how the OpenAI API works shows what an OpenAI-compatible endpoint is copying, and my roundup of open source LLMs helps you pick the model first.

Launching to users in Europe

If your app will serve people in the EU, there's one document I'd read before launch day. The European Commission describes the AI Act as the first-ever legal framework on AI, set up to address the risks of AI. Your inference provider won't decide which rules apply to your product. You will, so it's worth knowing the basics before a customer asks.

Do you make an inference API or model hosting platform? Tool makers can ask to be considered for a featured place on this list.

Plain advice before you switch inference providers

Don't move everything at once. Keep your current provider live, send a slice of real traffic or a fixed test set to one alternative, and compare answers, speed and error rates over a few days. If your code uses an OpenAI-compatible client, you can keep two providers wired in and fail over between them, which is the simplest insurance a small team can have.

Frequently asked questions

What does OpenAI-compatible mean for an inference API?

It means the provider accepts requests in the same shape as the OpenAI API, so existing client libraries work with a different base URL and key. It makes switching or running two providers side by side much easier.

Should a startup use one inference provider or two?

Two is safer once you have users. One handles normal traffic and the other is ready if the first slows down or changes a model. Keep the second wired in and tested, not just bookmarked.

How do I compare inference providers fairly?

Use the same model, the same prompts and the same settings on each, then compare output quality, response time and errors. Run it at the time of day your users are busiest, not just once.

Do I need to host open models myself to keep control?

Not necessarily. Hosted providers let you choose the model and switch between suppliers. Self-hosting gives you the most control but adds servers, updates and monitoring to your to-do list.

Is this list ranked?

No. The providers are listed alphabetically and in no particular order. The right one depends on your model, your traffic and the support you need.
