No public benchmark to compare AI coding assistants side by side

Developers comparing AI coding assistants like Codex and Claude Code lack shared benchmarks for success rate, code quality, token use, and response speed.

ProblemDevelopers choosing between Codex, Claude Code, and other AI coding assistants have no shared benchmark data to compare their actual performance across dimensions such as success rate, code quality, token efficiency, and response speed. Tool selection therefore relies on personal experience and community word-of-mouth rather than objective, comparable measurements.

What this evidence does not show yet

To reach Payment-backed we still need:

a first-hand payment statement — either someone naming what they already pay, or 2 more statement(s) with a specific amount they would pay (we have 0)
renewed mentions — the recent trend is below the promotion bar

No first-hand payment statement is on record here, so this page carries no pricing suggestion. A price with no payment evidence behind it is a guess wearing a number.

Scoring summary

Evidence confidence = strength × evidence volume × source diversity × payment × competition × trend × 10. Counts use independent content items; only first-hand pain, current spend, explicit willingness to pay and concrete feature requests affect the score. Repeated posts by one author are discounted. Scoring and status changes follow deterministic rules.

“Payment-backed” means first-hand payment evidence exists in the record. It does not mean the business is worth building. “Fading” is a recency tag shown alongside any evidence level, not a lower level. Read the full methodology.
