# qwen3-30b-a3b-fp8

> Model details for qwen3-30b-a3b-fp8. Multilingual, streaming, batch tasks, reasoning, and function calling with a 32K context window.

<Note>
  This model supports the Chat Completions API only. Send requests to
  `/v1/chat/completions` — the Responses endpoint (`/v1/responses`) is not
  available for this model.
</Note>

> Alibaba's Qwen3-30B-A3B is an open-weight Mixture-of-Experts model with 30.5B total parameters (3.3B active per token), served on ZeroGPU as an FP8 build for efficient inference. It thinks through a problem before answering and returns that reasoning alongside the final text, and it supports function calling, streaming, batch tasks, and 100+ languages with a 32,768-token context window. When you want frontier-style reasoning and tool use in a lighter, multilingual package, this is the model.

                            **1. Exponential backoff with jitter** – Retry on
                            429s with doubling delays plus randomness so your
                            retries don't stampede in sync.


                            **2. Client-side token bucket** – Throttle your own
                            outbound rate just below the provider's limit so you
                            never hit the wall in the first place.


                            **3. Cache and coalesce** – Cache hot responses and
                            merge duplicate in-flight requests so repeat calls
                            never reach the third party at all.

                            each. The classic answers: exponential backoff with
                            jitter, client-side throttling below the limit, and
                            caching plus request coalescing. Keep each to one
                            line.
