| Kai's verdict | A-tier. Best for teaching a kid to code in 2026. | 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 if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for academic research. Nothing else comes close for systematic reviews. |
