Qwen Flash is the fastest and lowest-cost model in Alibaba's Qwen family, served through Dashscope and built for latency-sensitive tasks. It delivers ultra-fast inference while supporting tool use (function calling), prompt caching, and web search. Context window: 1M tokens, output: 32K. The 1M-token context lets it scan long documents in a single pass, and prompt caching keeps repeated instructions cheap in high-volume pipelines. Available via OpenAI and Anthropic protocols.
