Qwen3.8-Flash

Qwen3.8-Flash is Alibaba's open-weight multimodal mixture-of-experts model released in August 2026, positioned as an early preview of the architecture planned for the Qwen4 series. The model combines a 125B-parameter main model with an additional 51B of N-gram embeddings and activates 6B parameters per token. It natively supports 262K tokens of context, extendable to 1 million.

Qwen3.8-Flash is aimed at high-volume agentic workloads: coding, tool-driven workflows, long-horizon office tasks, and multimodal intelligence. Alibaba reports competitive results against models like DeepSeek-V4-Flash and Claude Opus 4.6 on benchmarks including SWE-bench Pro, CoWorkBench, and Toolathlon Verified. Weights are on Hugging Face and ModelScope, with API access on Model Studio and Qwen Cloud at about $0.16 per million input tokens.
