Alibaba releases Qwen3.8-Max, open-sources weights next week
Alibaba's Qwen team officially released the flagship model Qwen3.8-Max and announced that weights for Qwen3.8-Max and Qwen3.8-27B will be open-sourced next week. The official positioning is as the strongest version to date, focusing on autonomous coding, collaborative work, and long-horizon tasks; the model has been integrated into Command Code Go and OpenRouter. For developers, the release is notable not only for performance but also for the simultaneous advancement of flagship capabilities and open-source cadence.
Confirmed
- Qwen3.8-Max uses a MoE architecture with 2.4T total parameters and 95B active parameters, supporting a 1M token context; official and related posts describe it as a natively multimodal model.
- The official claims it sets a new benchmark in coding and cowork, suitable for long-horizon coding, research, and multimodal agent tasks, and claims the model can autonomously develop from an empty folder for over 10 days without human intervention.
- The open-source plan is clear: weights for Qwen3.8-Max and Qwen3.8-27B will be released next week; Qwen3.8-Max has already been launched on Command Code Go and OpenRouter.
- For benchmarks and evaluations, the official promotes its general text capabilities with Text Arena results; forwarded posts summarize that it ranks 4th in Frontend Code Arena with a score of 1668. @ArtificialAnlys gives an agentic task index of 53, considering it close to Claude Sonnet 5; @davidthesong believes it is close to Kimi K3 and DeepSeek V4 Flash on many benchmarks but stronger on coding and software tasks.
Unconfirmed
- The official has not yet published the complete experimental setup, success rate, and reproducibility conditions for the "autonomous development over 10 days" test.
- No open-source license information is available in the current materials.
- Some forwarded posts mention API pricing of $2 per million input tokens and $6 per million output tokens, as well as a "cost reduction of 80%," but there is no corresponding official standalone post in this batch to cross-verify.
Why it matters
- Alibaba is not just releasing a larger model; it is bundling the flagship release, platform integrations, and next week's open-source announcement together, clearly courting developers and deployment ecosystems.
- If its coding, agent, and long-context capabilities are indeed close to current top closed-source models, the combination of Qwen3.8-Max and 27B could directly impact choices in programming assistants, enterprise applications, and open-source deployment markets. @op7418 also noted that this feels like a "reset" style official release, indicating Qwen's product line is entering a new round of flagship competition.
