Compiler dev test: Meta's Muse agent ships clean, Gemini 4 left a mess
QuixiAI · x · 2026-10-18
The author ran two models on building their With compiler and posted a detailed agent-review screenshot. Gemini 4 Argon moved the project far in 1.5 days (merging PRs for loop hoisting, wasm32 bundles, etc.) but compounded a self-host regression to 11%, never measured the corpus suites it claimed were within 5%, lost a key comptime fix in a merge, cited a nonexistent CLI flag in PR #2445, and let process slips pile up. Muse Wonder Full, under a similar test, made no mistakes. Author's verdict: for compiler development, Meta's Muse Wonder Full clearly beats Gemini 4 Argon. Note: these model names are recent and this is an individual test, not a standard benchmark.
