LLM API Providers Compared — 11 Providers, 32 Models, Updated August 2026
Raw dataset: data.json.
Amazon is the cheapest provider by entry-level current-model price. Cerebras is the fastest by median measured throughput, at 2215 tokens/sec. Google has the widest context window, at 2M tokens.
How to read this: "lab" providers train the weights they serve; "host" providers (Groq, Cerebras) serve someone else's open-weight models on their own inference hardware — their differentiator is speed, not model quality.
