|---|---|---|---|
| Tagline | The fastest AI inference in the world. Crazy low latency. | VS Code fork that made AI coding actually work. | Blazing-fast, pay-as-you-go inference API for open-source LLMs and multimodal models, now plugged directly into the Hugging Face ecosystem. |
| Category | Dev Platform | Coding | Dev Platform |
| Pricing | Free tier + pay-as-you-go API | Free + $20/mo Pro + $40/mo Business | Free $5 credit on signup, then pay-as-you-go from $0.06/M tokens |
| Best for | Developers who need sub-100ms LLM responses. | Developers. Non-developers who want to ship working code. | Backend developers and ML engineers who want the cheapest reliable inference for open-weight LLMs in production, especially those already living inside the Hugging Face ecosystem. |

| Kai's verdict | S-tier for speed. When latency is the product, start here. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | DeepInfra is the quiet workhorse of the inference API space — serious price performance on H100s, a genuinely clean OpenAI-compatible API, and now a native HF provider makes it a strong default choice for any team running open-source models at scale. (Verdict pending Phi's full review.) |
