About
Qwen3.8-Flash-Next is Alibaba's experimental open-weight preview of the architecture planned for Qwen4. It is a 125B-total / 6B-active Mixture-of-Experts causal language model with a vision encoder, plus 51B n-gram embedding and 4B MTP parameters. Native context is 262,144 tokens (extensible to 1,000,000). Weights are on Hugging Face under the Qwen Community License 1.0. No first-party hosted token prices are seeded.
