Grok 4.6 Coding Test: Strong Core Logic, Weak Boundary Handling
jquinonero · x · 2026-08-17
The author tested Grok 4.6 within a coding team (via Cursor) against Codex Sol 5.6 and Claude Fable 5. Verdict: Grok excels at core logic, data integrity, and non-obvious architectural decisions, but systematically fails at boundary checks (e.g., missing files, broken contracts, unparsable client JS). Codex and Claude remain more polished and holistic choices for now.
