CODEX SHIPS CLI THREAD ARCHIVE, FIXES BEDROCK SERVICE TIER LEAKS

By RepoJournal · Filed · About OpenAI · Composed from the cited sources · methodology

Codex now lets you archive threads from the command line, while a critical fix prevents the system from advertising unsupported Bedrock service tiers.

The top story is straightforward: `codex archive` and `codex unarchive` commands are live [1], finally closing the gap between app-server RPC capabilities and what the CLI exposed. These commands resolve UUIDs or thread names and support scoped remote flags for multi-endpoint deployments. In parallel, a critical fix landed that strips non-default service tier metadata from Bedrock model catalogs [2], preventing Codex from advertising GPT models with tiers Bedrock doesn't actually support. This is a silent failure prevention: end users would have hit errors trying to use those tiers. On the multi-agent front, the v2 assignment tool got renamed from `followup_task` to `assign_task` [3] with backward compatibility preserved in rollout traces, keeping legacy classification intact while modernizing the API surface.
