The shape of the graph is getting very familiar. Claude Fable 5 scores very well on FrontierMath: Tiers 1-4 (v2), reaching 87% on Tiers 1-3 and 88% on Tier 4. This continues a streak of Anthropic models improving rapidly at math.

If the leaked financial data is right, OpenAI is profitable on serving customers with 40%+ gross margins. But training remains incredibly expensive. Automating AI research may also be a play to increase the efficiency of training: a superhuman researcher could do more with less.

Show Codex a workflow once. Reuse it as a skill. Record & Replay lets you show Codex a recurring task, like filing an expense report or submitting a time-off request. Codex turns that demo into an inspectable, editable skill. You control when recording starts and stops.
