Qwen Previews Qwen4 With Open-Source Flash Model
💡Get an early, open-source look at the architecture behind Alibaba’s upcoming Qwen4.
⚡ 30-Second TL;DR
What Changed
Qwen3.8-Flash-Next is scheduled for open-source release on Aug. 26 at 11 p.m. Beijing time.
Why It Matters
An open-source preview of Qwen4 could give developers earlier access to Alibaba’s next-generation model architecture and enable faster experimentation. The FP8 release may also support more efficient inference deployments, subject to hardware and software compatibility.
What To Do Next
When the release goes live, download both Qwen3.8-Flash-Next and its FP8 checkpoint, then benchmark latency, memory use, and multimodal accuracy on your target hardware.
Key Points
- •Qwen3.8-Flash-Next is scheduled for open-source release on Aug. 26 at 11 p.m. Beijing time.
- •An FP8 version will be released alongside the main model.
- •The model uses a multimodal mixture-of-experts design based on Qwen4 architecture.
- •The early release is intended to help developers prepare for the full Qwen4 launch.
