The Codex speed button now cycles Regular → Fast → Ultrafast → Regular, skipping unsupported tiers. Ultrafast uses the existing MIT-licensed icon from bb’s Codex provider, persists across reloads and resumes, and reaches Codex. Existing boolean preferences, both fast/priority config aliases, and Claude's two modes keep working.

Regular Fast Ultrafast
Regular picker Fast picker Ultrafast picker

Verified with the browser controls on local Codex 0.165.0 / 6.1 Sol:

Mode Native turn/start.serviceTier Completed reply
Regular null REGULAR_OK
Fast "priority" FAST_OK
Ultrafast "ultrafast" ULTRAFAST_OK

Restart persistence and the two-state fallback on 6.1 Terra also pass.

Compatibility checks used separate clients and isolated auth/state:

  • 0.147.0 / 5.6 Sol: live regular and fast replies pass; Ultrafast is not advertised.
  • 0.165.0 / 6.1 Sol: live replies pass in all three modes.
  • 0.134.0: tier wire schema is compatible, but the client cannot decode today's model catalog (max effort) and the account rejects its bundled models; generation remains unverified.
  • Tests cover missing metadata, legacy additionalSpeedTiers, authoritative serviceTiers, saved-mode fallback, and Fast config aliases.

Linux CI pins Ubuntu 24.04 to avoid the native-addon crash on the new Ubuntu 26.04 runner. CI uses Bun 1.4.4, the current stable release. The lockfile's Bun type entries match the declared dependency.

Validation: TypeScript, lint, formatting, repo checks, client build, 155 focused tests, and the full local suite pass (2,404 pass, 4 skip) with an isolated data directory. Linux and Windows CI pass on Bun 1.4.4, including all 2,408 Linux tests and the package build and inspection.
