fix(pricing): add OpenAI/Codex model pricing, stop hardcoding cost to $0 - #23
Merged
Conversation
Codex CLI sessions always reported $0 estimated cost because estimatedCostUsd was hardcoded in codex.ts, and the shared pricing table had no entries for any OpenAI/GPT model at all. Adds pricing for the current GPT-5.x/Codex, GPT-4.x, and o-series models, and wires codex.ts to actually calculate cost from usage. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Summary
estimatedCostUsdwas hardcoded to0incodex.tswith a "Codex pricing not public" comment, andpricing.tshad zero OpenAI/GPT entries in its pricing table.MODEL_PRICING.codex.tsto callcalculateCost()instead of hardcoding 0.gpt-4o-minias an "unknown model" placeholder (it's now a known model) and added a coverage test forgpt-5.6-terra.Related follow-up tracked separately: #22 — move pricing to a DB-backed table with periodic updates instead of a hardcoded map, so new models/price changes don't require a code release.
