FAQ

Frequently asked questions about Qwen3.5-122B-A10B

How does Qwen3.5-122B-A10B compare with Qwen3.5-397B-A17B?

Alibaba ranks the 122B model second only to the 397B flagship. It activates 10B parameters per token against 17B for the flagship. Both have a 262,144-token context window, image input, and hybrid thinking.

Can Qwen3.5-122B-A10B replace Qwen3-VL-235B for image tasks?

Alibaba says the vision capability of Qwen3.5-122B-A10B exceeds Qwen3-VL-235B, and it also has twice the context window. Test it on your own images before you move a production workload.

Does Qwen3.5-122B-A10B think before answering?

By default, yes. It has thinking and non-thinking modes, and Alibaba's API turns thinking on unless the request switches it off. Thinking makes responses longer, so allow more time on sync requests.

Which API do I use to call Qwen3.5-122B-A10B?

Use RunAPI's OpenAI-compatible Chat Completions endpoint at https://runapi.ai/v1/chat/completions with your RunAPI API key and model set to qwen3.5-122b-a10b. Tools use the standard OpenAI tools format.

How do I select qwen3.5-122b-a10b?

Pass the model ID shown in the quickstart.

What's the rate limit on this variant?

Per-key rate limits scale with your usage tier. The pricing page shows current limits. If you need higher throughput, contact support to discuss tier upgrades.

Can I switch variants later?

Yes. Variant is a parameter in the request. Switch by changing the model ID — no code changes, no re-authentication, no separate billing setup. All variants share the same API key and request shape.

Does it stream?

Where streaming is available, RunAPI streams end-to-end. LLM models support token-level streaming. Media models use async task polling or webhook callbacks for result delivery.

Where do I report quality issues?

Open an issue on the public GitHub repo or email support at [email protected]. Include the task ID and model ID so the team can investigate the specific generation.

Do I need a separate provider account?

No. Your RunAPI API key is enough to access this variant and every other model in the catalog. You do not need accounts with the underlying provider.
