Best AI Model Hosting & Inference for startups
Last verified:
Crail tracks 6 AI Model Hosting & Inference vendors that list startups as a fit. These are the 5 that rank highest once the list is weighted for startups, and each one is shown with what it costs to start and whether you can start today without a contract — the facts that decide the shortlist at this size, rather than the same summary on every page.
How this list is weighted for startups
- 60% of the vendor's Crail agent-readiness score
- 15 points for a published free tier
- 15 points for being buyable self-serve, without a sales call
- up to 10 points for a low entry price (free tier, then a cheapest paid tier under $30, then under $75)
Startups and small businesses share the price-and-self-serve weighting; midmarket and enterprise share the compliance weighting. The full rules are on the methodology page.

FAQ
How is this AI Model Hosting & Inference ranking calculated for startups?
This is not the raw agent-readiness leaderboard. Crail scores the 6 AI Model Hosting & Inference vendors it tracks that fit startups, using 60% of the vendor's Crail agent-readiness score; 15 points for a published free tier; 15 points for being buyable self-serve, without a sales call; up to 10 points for a low entry price (free tier, then a cheapest paid tier under $30, then under $75). Fireworks AI ranks first on both measures: it holds the highest raw agent-readiness score on this list (77/100) and the top score once the startups weighting is applied.
Which of these can a startup use without paying?
4 of the 5 publish a free tier: Fireworks AI, Groq, Modal and Baseten. None of them are open source.
Do any of them require a sales call before you can buy?
No. All 5 can be bought self-serve, without talking to sales.
