Summary

Anthropic's Claude Fable 5, recently lauded as "the best coding model in the world," demonstrates significant capabilities, particularly for advanced developers. While many knowledge workers perceive its improvements as incremental and note its cost is "twice as much" as previous models, a distinct group of "Level 7 or 8" AI users, such as Cora general manager Kieran Klaassen, are experiencing its full potential. These users delegate entire projects, employ asynchronous agents, meticulously review results, and integrate learnings into subsequent runs, effectively "writing loops, not prompts." This sophisticated workflow enables them to resolve bug fixes and feature requests in hours instead of days.

Key takeaway

For AI Engineers aiming to maximize model utility and accelerate development cycles, consider adopting "Level 7 or 8" AI usage patterns. Shift from simple prompting to designing iterative, agent-based workflows where you delegate projects, review outputs, and integrate feedback. This approach, exemplified by Claude Fable 5 users, can dramatically reduce task completion times from days to hours, transforming your operational efficiency.

Key insights

Advanced AI users leverage iterative, agent-based workflows to maximize models like Claude Fable 5 beyond simple prompting.

Principles

• AI adoption scales to "Level 7 or 8" for full impact.
• Developer workflows often spread to broader knowledge work.
• Treat work like "gardening" for optimal AI integration.

Method

Delegate whole projects, allow agents to work asynchronously, review results, and feed learnings into subsequent runs, effectively "writing loops, not prompts."

In practice

• Resolve bug fixes and feature requests in hours.
• Automate slide decks and spreadsheets with agent methodologies.
