Context
A sponsored Traycer demonstration illustrates how planning and coding can be divided between models. Anthropic’s Fable 5 assigned successive flight-simulator milestones to a locally running Qwen 27B model, reviewed its code and sent corrections before continuing. When the local model ran into and execution problems, the presenter eventually asked the supervisor to finish the remaining edits. The example shows a coordination workflow with review and recovery, but it cannot establish a cost or quality advantage: the comparison used one build per setup, and the supervised version included direct edits by the supervising model.
- context window — The maximum amount of text a model can consider at once — its working memory for the current conversation or task.
- multi-agent — Using several AI agents on one problem — splitting work in parallel, checking each other, or filling different roles like planner and reviewer.
“rather than handing it the whole game at once which it would likely thrash on”
“The builder reports milestone one is done. Before assigning the second one, I'm going to verify the claims by reading the code.”
“the builder had correctly implemented a pitch direction despite my instructions containing an error. It followed the real instrument principle over my parenthetical”
“Roughly 30 substantive defects were found across four fixed rounds. None survived to the final build.”
“being able to have them used less frequently to control a cheaper, smaller, but still capable model like this is going to become more and more popular”
