Anthropic discusses Claude Platform engineering and Opus 5.5

What happened

AI digest

On 28 October 2026, the Latent Space podcast hosted Anthropic's Katelyn Lesse and Angela Jiang to explain the engineering behind Claude Platform. The episode covers the release of Opus 5.5, a design that decouples the model's "brain" from the agent's "hands", API scaling, and building reliable hosted agents. Later the same day, Latent Space published another episode on the same subject, naming the interviewees as Anthropic engineering lead Katelyn Lesse and product lead Angela Jiang, reviewing the Opus 5.5 release process and the engineering trade-offs of Claude Platform, and mentioning "building Claude with Claude". Both reports come from the same podcast and differ slightly on the guests' titles: the earlier report gives no titles, while the later one calls Lesse engineering lead and Jiang product lead. Public information still comes only from this podcast, with no other reports yet on Opus 5.5's specific release date, performance figures or platform scaling details.
