| 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 multilingual video. If you sell courses or speak at events, this is a cheat code. | S-tier for academic research. Nothing else comes close for systematic reviews. |
