| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | S-tier for open-source model APIs. The default in this space. | 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.) | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. |
