Qwen3.6 Flash
Provider list prices: no platform markup, pay-as-you-go. These are official list prices. Logged-in customers may see effective prices including workspace discounts on /console/pricing. Effective input at a 70% cache-hit rate:$0.11/M. Implicit context cache is automatic; an explicit cache_control mode offers deeper discounts (1,024-token minimum blocks, 5-minute TTL that resets on hit). Per-model cached-read prices are in the pricing table.

Qwen3.6 Flash is the fast, economical tier of the Qwen3.6 generation, which the Qwen team framed as a move "Towards Real World Agents." Versus Qwen3.5, the generation's official announcement highlights drastically enhanced agentic coding from frontend work to repository-level tasks, improved multimodal perception and reasoning accuracy, and a new preserve_thinking option that carries reasoning content across turns to keep agent decisions consistent while reducing token use.
- Flash trades some depth for lower latency and cost.
- Synthorai serves it over the OpenAI-compatible endpoint.
