Model Information

Display Name: Qwen 3.8 Flash

API Model ID: qwen/qwen3.8-flash

Category: Image To Text

Description: Qwen 3.8 Flash is Alibaba's fast multimodal reasoning model — the Qwen 3.8 generation of the Flash line. It reads text, images and video, switches reasoning on and off per request, and is tuned for agents, visual coding, document and long-video analysis at a fraction of the flagship cost. **Key Features:** - 1M token context window - Up to 131K output tokens - Vision + video input (text output) - Hybrid thinking: off by default, on via parameter (up to 262K reasoning tokens) - Function/tool calling and structured outputs (JSON mode) - Prompt caching for cheaper repeated context - Streaming support **Best For:** - High-volume multimodal workloads - Visual agents, UI automation and document understanding - Long-context and long-video processing on a tight budget - Fast classification, extraction and routing

Context Window: 1,000,000 tokens

Max Output: 131,072 tokens
