Elon Musk shared that Grok 4.7 is in final polish, explaining that RL over-penalizing token length caused models to surrender prematurely on hard problems. The team is correcting length penalties and rigor before release in days.
Key Takeaways
Grok 4.7 completed base pretraining, now undergoing RL reward signal fine-tuning
Removes token length penalties causing premature model surrender on complex reasoning
Bolsters multi-step verification and reflection ahead of full rollout in days

Official @ClaudeDevs: Claude Code adds `claude plugin eval`βauthor test cases, score a plugin/skill against a no-plugin baseline (terminal + HTML), then `claude update`. Docs at code.claude.com/docs/en/plugin-evals. Evals burn tokens; MCP/hooks run as configured.
Key Takeaways
Official claude plugin eval command to quantify plugin/skill value.
Test cases with plugin vs no-plugin baseline; terminal + HTML reports.
Requires Claude Code update; evals use tokens and run MCP/hooks.
Elon Musk said Grok 4.7 still needs a few more days. He suggested RL may have penalized response length too much, causing the model to give up too early on hard tasks it can do and to check its work insufficiently.
