| 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.) | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. | B-tier. Still early. Manus is more flexible for less money. |
