Claude's Next Model Codename "Fennec" - Launch Within a Week? Additional Rumors
Rumors are spreading that Anthropic's next model "Fennec" could launch as early as within a week. Context window expansion is also being speculated.
Additional rumors about Anthropic's next model "Fennec," which we covered in our previous article, are pouring in. Predictions of a launch 'as early as within a week' are spreading across X and Reddit.
Launch Within a Week?
Prediction markets on Manifold show active betting on Sonnet 4.7's release timing, and voices expecting an imminent launch are growing in various communities. On Reddit r/ClaudeAI, some even suggested "within weeks, not months."
However, there's no official announcement, and these are all at the rumor level. The prevailing analysis is that competitive pressure from GPT 5.3 and Gemini 3.0 is accelerating the release schedule.
Context Window Expansion?
Rumors on Reddit suggest Fennec's context window could expand beyond the current capacity. The current limit for general users is 200K, which has been criticized for frequent auto-compaction and context loss. If the context window expands, this could provide a much more stable experience for extended work sessions.
There are rumors that pricing could fall between current Sonnet 4.5 ($3/$15 per MTok) and Opus 4.5 ($5/$25). If it delivers Opus-level performance at Sonnet pricing, it would be highly competitive.
4.7? Or 5.0?
There are also rumors about the model name. Reports on Reddit suggest Claude 5-related code was found in Claude Code v2.1.23. A new 'max' level appears to be separated from existing Claude 3.x and 4.x models. Some speculate it may launch as Claude 5.0 rather than Sonnet 4.7.
Conclusion
Nothing has been officially confirmed yet, but internal testers and various rumors continue to mention an imminent release. Performance exceeding Opus 4.5 at a lower price, plus potential context window expansion—significant improvements are being mentioned, making this worth watching.
