Claude Code vs Pi — Pi vs Claude Code: 3 side-by-side tests
3 posts from X ran Claude Code and Pi on the same task, between Oct 26, 2026 and Oct 28, 2026. Models: GPT-6 Astra, Gemini 4 Argon, Claude Opus 5.5, GPT-6.1 Terra, GPT-6.1 Sol. All harness comparisons.
- 3 posts state a time for both: Pi was faster in 2 (Claude Code 1, Pi 2), median gap ~1.7×.
- 3 posts state a cost for both: Pi was cheaper in all 3, median gap ~2.7×.
- None keeps the model fixed: each side ran its own model, so harness and model effects are mixed — not a controlled comparison.
From 3 posts; costs and times as stated by each author, not a controlled benchmark.
