Developer ScriptedAlchemy shares a week-plus hands-on review of Grok 4.7, calling it a major improvement over 4.6:
- Worked autonomously toward one goal for over 70 hours straight
- Much better attention to detail
- The 500k context window reportedly makes a real difference
- Notably stronger at skill selection and workflows, especially with pstack
He couldn't test it in Grokbot but says it's already a great daily driver.
