Qwen3.5 Flash API
Released February 2026 | 1M Tokens (API) / 256K Tokens (self-hosted base) context | 35B params (3B active) — hosted parameters
Qwen3.5 Flash API enables High-volume agentic workflows, Cost-efficient RAG pipelines, Real-time chatbots and assistants, Code generation and review, Tool-calling automation, and Large-document analysis. Qwen3.5-Flash is the production-hosted, closed-source API version of the Qwen3.5-35B-A3B model, served via Alibaba Cloud Model Studio. It delivers frontier-adjacent intelligence at roughly 1/13th the cost of Claude Sonnet 4.6, with a 1M token context window, native tool calling, built-in web search, and code interpreter support. Responses are 6x faster than Claude Sonnet 4.6 with competitive quality on agentic benchmarks. Standout strengths include 1M token context window — no RAG chunking needed and 1/13th the cost of Claude Sonnet 4.6 ($0.10/M input). It is well suited for multimodal assistants that combine image understanding with grounded text reasoning in real-time workflows.
