# Qwen3.6-Flash

> Qwen3.6-Flash vision-language model via Alibaba via AnyFast OpenAI-compatible API. Fast, agentic, and multi-modal.

Qwen3.6-Flash is Alibaba's native vision-language Flash model, available through AnyFast via an OpenAI-compatible interface. It delivers significant improvements in agentic coding, math/code reasoning, and spatial intelligence compared to Qwen3.5-Flash.

## Key capabilities

* **OpenAI-compatible** — Works as a drop-in replacement with the OpenAI SDK
* **1M token context** — Handles massive documents and conversations with up to 66K output tokens
* **Multi-modal input** — Supports text, image, and video inputs
* **Agentic coding** — Substantially improved coding agent benchmarks
* **Reasoning** — Built-in thinking support via `enable_thinking` parameter
* **Built-in tools** — Web search, code interpreter, web scraping, image search via Responses API
