/architect: Reduce Fable tokens by 80%, Fable orchestrates/reviews, Codex builds (github.com)

Claude Fable introduces a groundbreaking framework that significantly reduces operational costs for AI/ML projects by cutting Fable token usage by 80%. This system distinguishes itself by employing two roles: Fable acts as the architect, designing and reviewing each project slice, while GPT-5.5 Codex serves as the builder, executing engineering tasks in parallel without requiring extensive API configurations or incurring high token bills. This streamlined approach allows for efficient project management, with automated processes to ensure quality and adherence to specifications. The framework integrates a unique parallel processing mechanism where isolated builders are dispatched based on detailed, evidence-backed designs that maximize productivity and minimize errors. Key features include a research phase that utilizes Codex as a scout to gather relevant data, creating topic-specific workstreams informed by verified sources. The incorporation of strict oversight via built-in liveness checks and clear documentation helps maintain project integrity and ensures that every component is verifiably sourced. This structured approach enhances productivity and could influence future development methodologies within the AI/ML community, promoting a more disciplined and efficient model for collaborative software development.
