OpenAI and Anthropic public-post watch

Checked 16 August 2026 at approximately 3:10 am AEST (5:10 pm UTC on 15 August). Priority window: the preceding 24 hours. Items already covered in the 15 August bulletin were excluded.

Headlines

• Codex multi-agent delegation can now choose any supported model, including Luna — OpenAI Codex developer-experience engineer Eric Provencher said the multi-agents v2 system can delegate work to any supported model, following reliability work on the feature. Greg Brockman amplified the update as progress toward a system in which users do not have to select models manually. The shipped capability is cross-model delegation; Brockman’s broader automatic-selection framing is directional and does not establish that a fully automatic model router has shipped.

Anthropic watch

• No new substantive employee post since the previous check — The public main-feed timelines reviewed did not surface a new Anthropic product, research, developer, policy, or company update after the 15 August bulletin. Jack Clark’s research-hillclimb post remains inside the rolling 24-hour window but was already covered yesterday and is not repeated here.

Steve Yegge watch

• No fresh visible post in the priority window — Steve Yegge’s public main-feed timeline still showed 11 August as its newest visible post, so no older item was recycled.
