Qwen3.6 Flash
How TheRouter serves this differently from the vendor
Alibaba Cloud Model Studio lists qwen3.6-flash as a Qwen3.6 model with 1M context, thinking mode, function calling, built-in tools, and structured output. The upstream pricing card is tiered at 256K input tokens for international usage.
TheRouter serves qwen/qwen3.6-flash through the OpenAI-compatible chat route as text-in/text-out with 1,000,000 catalog context, 32,768 max output, and supported parameters temperature, max_tokens, top_p, tools, tool_choice, response_format, and stop. The current TheRouter catalog does not expose Alibaba's enable_thinking control as a public reasoning parameter for this route.
