Summary
After more than 500 hours with both models in Claude Code, Peter Yang explains when to reach for Claude Fable 5.2 and when to stay with Opus 5.5. His rule of thumb: Opus remains the best daily driver for execution-heavy work, while Fable is best reserved for the hardest, highest-stakes tasks such as career strategy, long-running open-ended projects and complex workflows. Fable costs about twice as much per token on the API and can consume up to half of a weekly limit on the Max plan.
The video shares four tips attributed to Anthropic’s Alex: ask Fable what is wrong with your idea before it builds, start at medium or high effort rather than extra high or max, state up front what needs approval, and hand it a whole project rather than a single step.
Yang then demonstrates real use cases. He sets up a chief of staff for email and calendar using Opus, with Gmail, Google Calendar and Slack connected through connectors, and builds a podcast sizzle reel by combining Riverside and Suno MCP integrations. He also covers an advisor setup, an automated weekly workflow and a system for supporting a loved one through illness. The video is sponsored by Anthropic, and the prompts are included in the description.
