bindureddy · x · 2026-08-14

The author compares Grok 4.6 against top open-source models like Qwen and Kimi K3. Grok 4.6 scores just below the leading tier but is more usable than K3 due to its speed, making it a solid replacement for Sonnet 4.5 workloads. However, the author explicitly debunks claims that it reaches the capability of Fable or Opus.
