For primary quotes and complete technical detail, see HN Claude/Codex/Fable's original report linked above.
Developer Action Items
- ☐ Verify the claim on the official Claude / Opus / Codex page (or HN Claude/Codex/Fable), not from this recap alone.
- ☐ Name the surface that moved — API, policy, model, hardware, or commercial terms — before you Slack the thread.
- ☐ Assign one owner a day to read the primary material and decide: this-sprint, this-quarter, or noise.
- ☐ Do not change production on day-one coverage. Watch the vendor changelog and one independent write-up first.
