| Kai's verdict | 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.) | S-tier for solo + free. The best free option, hands down. | S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. |
