Where Claude Haiku falls behind Opus: 163 coding runs with hidden tests
163 headless runs (plus 11 excluded) of Claude Code (Haiku 5.5, Sonnet 5.5, Opus 5.5), Codex (gpt-6-luna) and Antigravity CLI (Gemini 4 Argon) on six levels of coding tasks, measured 2026-10-23 to 24 on one Windows 11 laptop.

Key findings
- Levels 2 to 5 (apps from a spec, and an existing 1,032-line app with six symptom-only bugs plus three features): Haiku, Sonnet and Opus got full marks on all 21 runs each, Gemini 18/18, Codex 17/20.
- Level 6, three real bugs fixed in the marked Markdown parser in Sep to Oct 2026: the easy and medium bugs were solved by almost every run. No run fully fixed the hard one (7-case upstream test), but the models split: Sonnet passed 6 of 7 in 8 of 10 runs, Opus in 6 of 10, Haiku in 1 of 10. The missed cases are code spans containing a backtick, which the bug report did not mention.
- Letting the agents run the tests (dependencies preinstalled,
node,npm test/npm run, read-only git allowed; 5 runs per Claude model) did not change the cases passed. It removed damage: without tests 2 of 15 Claude runs broke other spec tests (one Opus run left marked unable to load), with tests 0 of 15. Codex was also run with tests allowed, but its Windows sandbox blocked esbuild in all 5 runs (excluded). - Average API cost per run (Claude Code's own figure): Haiku $0.026, Sonnet $0.19, Opus $0.45.
Files
Prompts, checkers, reference solutions and every run log are in the GitHub folder: https://github.com/johnisking/token-cost-by-language/tree/main/limit-line
ai-coding-limit-line.csv/.json: one row per run (score, full marks, seconds, tokens, cost, notes; level 5 and 6 detail columns).excludedmarks runs stopped by the harness or by quota.prompts/: every prompt (tier2 to tier5b, tier6_t1 to t3, and tier6_t3_dev for the tests-allowed runs).checkers/: the hidden-test checkers (Playwright, Python) and the tier-6 scorer.ref/,tier5a/,tier5b/: reference solutions, the planted-bug base app and broken variants used to validate the checkers.results/: raw checker output per level.runs/<tool>[dev]_t<level>_r<n>/(dev= tests allowed): each run's log (run.jsonlorrun.json),seconds.txtand the code it produced (work/; for level 6 onlywork/src). The PC user name is replaced by USER.build_dataset.py: builds the CSV/JSON from the results and logs.
Notes
- Level 6 scoring: a clean checkout of the commit before the upstream fix plus only the run's
src/, the upstream fix's spec file added, then marked's spec suite. 1 point if the hidden spec passes and no other spec test newly fails. - Antigravity's headless mode ends a turn at the first denied command. Gemini runs used read-only allow-rules; the level 6 runs were repeated with full permissions (
geminifull_*, run by the owner). - Few runs per cell at the higher levels (1 to 5); see the page for all limitations.
