Grok 4.6 and Qwen3.8 Launch Next Week, Astra Absent
According to multiple leakers, xAI's Grok 4.6 and Alibaba's Qwen3.8 are expected to launch next week. Grok 4.6 will retain the 1.5T-parameter V9 base, focus on post-training improvements, enhance writing and design quality, and collaborate with Cursor. Qwen3.8 is expected to open-source a 27B-weight version and release a 2.4T-parameter flagship, Qwen3.8-Max. Google's Astra project will not launch next week. These releases will intensify competition in writing, design, and coding.
Confirmed
- xAI engineer Lee Robinson stated that the team is significantly improving Grok's writing quality and design taste, and teased that Grok 4.6 is coming soon, inviting user feedback.
- Leaks indicate that Grok 4.6 will continue to use the 1.5T-parameter V9 base but focus on post-training with large-scale SFT and RL upgrades.
- xAI is reportedly working closely with Cursor to optimize model performance, and Cursor's Composer 3 is expected to launch next week alongside.
Unconfirmed
- The exact release dates for Grok 4.6 and Qwen3.8 have not been officially confirmed; leaks only say next week or early this week.
- Specifics of Alibaba's Qwen3.8 are only from leaks: an open-source 27B-weight version and a 2.4T-parameter flagship Qwen3.8-Max.
- The claim that Google's Astra won't launch next week comes from a single leak source.
Why it matters
Grok 4.6's release will intensify competition in writing and design, and its collaboration with Cursor and Composer 3 could advance agentic coding workflows. Meanwhile, if Alibaba releases a 2.4T-parameter flagship, it could spark a new round of competition in open and closed-source LLMs.
