Qwen reports that the 27B dense model surpasses the Qwen3.5 flagship in agentic coding. Both have a 262,144-token context window and accept images. Compare them on your own coding tasks before you switch. ### Should I use Qwen3.6-27B or Qwen3.6-35B-A3B? Qwen3.6-27B is dense, so all 27B parameters run for every token. Qwen3.6-35B-A3B is a Mixture-of-Experts model that activates 3B parameters per token. Qwen positions the 27B model for flagship-level agentic coding. ### What improved from Qwen3.5-27B? Qwen3.6-27B is built on Qwen3.5-27B. Qwen reports better agentic coding, STEM reasoning, spatial intelligence, OCR, and video understanding. ### Does Qwen3.6-27B support tool calling on RunAPI? Yes. Alibaba lists function calling as supported. Send tools in the OpenAI format on Chat Completions and the model returns tool_calls. ### How do I select qwen3.6-27b? 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 contact@runapi.ai. 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. ### RELATED - [qwen3.5-35b-a3b](https://runapi.ai/models/qwen/qwen3.5-35b-a3b.md) — by Alibaba · Input $0.25 / 1M tokens | Output $2.00 / 1M tokens - [qwen3.5-27b](https://runapi.ai/models/qwen/qwen3.5-27b.md) — by Alibaba · Input $0.30 / 1M tokens | Output $2.40 / 1M tokens - [qwen3.6-35b-a3b](https://runapi.ai/models/qwen/qwen3.6-35b-a3b.md) — by Alibaba · Input $0.38 / 1M tokens | Output $2.25 / 1M tokens - [qwen3.5-122b-a10b](https://runapi.ai/models/qwen/qwen3.5-122b-a10b.md) — by Alibaba · Input $0.40 / 1M tokens | Output $3.20 / 1M tokens ### Start building with Qwen. - [Create free account](https://runapi.ai/login) - [Read the quickstart →](https://runapi.ai/docs/api/openai/chat-completions) ## Building with a team?
