Strengths and weaknesses
- +Top-ranked output speed on shared models (~322 t/s on Llama 3.3 70B per Artificial Analysis), far above typical GPU providers
- +Very low time-to-first-token (sub-1s), ideal for real-time agents and voice pipelines
- +OpenAI-compatible API, migrate with a one-line base-URL change, reuse existing OpenAI SDK code
- –Open-weight models only, no Claude, GPT-4-class, or Gemini
- –Persistent rate-limit and over-capacity (429) complaints; free tier is tight (~30 RPM)
- –Rate limits are pooled per-organization, not per-key, so adding keys does not raise capacity
- +Access to the highest-intelligence models available, GPT-5.5 leads the Artificial Analysis Intelligence Index at 55
- +Extremely fast onboarding: self-serve key generation in under a minute and clean REST endpoints
- +First-party SDKs in Python, JS/TS, .NET, Java and Go plus an Agents SDK
- –Expensive output tokens on flagship models ($30/1M on GPT-5.5) make high-volume generation costly
- –Flagship reasoning models are slow, ~62 tok/s and ~28s TTFT on GPT-5.5 high
- –Standard pay-as-you-go tier has no uptime SLA; guarantees require Scale Tier or Azure
