Bug in Codex's AWS Bedrock Integration Triggers 10x Overcharges
A GitHub issue filed against OpenAI's Codex project describes a bug where usage routed through AWS Bedrock results in charges roughly ten times higher than anticipated. The issue has drawn attention on Hacker News, with developers sharing similar billing surprises after integrating Codex with Bedrock-hosted models.
While exact technical details are still being worked out in the thread, the pattern suggests a miscalculation somewhere in how token usage or request counts are tracked and billed when Codex talks to Bedrock's API layer instead of OpenAI's own infrastructure.
As of this writing, the issue remains open, with commenters comparing notes on their AWS invoices and asking OpenAI for a fix or clearer documentation on how the integration bills usage.
