Qwen/Qwen3.5-Flash
Qwen3.5-Flash is the production-hosted, closed-source API version of the Qwen3.5-35B-A3B model, served via Alibaba Cloud Model Studio. It delivers frontier-adjacent intelligence at roughly 1/13th the cost of Claude Sonnet 4.6, with a 1M token context window, native tool calling, built-in web search, and code interpreter support. Responses are 6x faster than Claude Sonnet 4.6 with competitive quality on agentic benchmarks.

Complete parameter documentation
| Parameter | Type | Default | Description |
|---|---|---|---|
| stream | boolean | true | Enable streaming responses for real-time output. |
| temperature | number | 0.6 | Controls randomness. Use 0.6 for non-thinking tasks, 1.0 for thinking/reasoning tasks. |
| max_tokens | number | 8192 | Maximum number of tokens the model can generate. |
| top_p | number | 0.95 | Controls nucleus sampling for more predictable output. |
| top_k | number | 20 | Limits token sampling to top-k candidates. |
| enable_thinking | boolean | false | Toggle chain-of-thought reasoning mode. Use temperature=1.0 when thinking is enabled. |

Performance
Strengths & considerations
| Strengths | Considerations |
|---|---|
| 1M token context window — no RAG chunking needed 1/13th the cost of Claude Sonnet 4.6 ($0.10/M input) 6x faster response than Claude Sonnet 4.6 Built-in official tools: web search, code interpreter Supports Thinking and non-Thinking modes Native function calling and structured output | Closed-source — no self-hosting or weight access Maps to 35B-A3B capability tier, not the full 397B Requires Alibaba Cloud API access Production features like 1M context only available on hosted API |
