Avila shares Sonnet 5, Fable 5 matrix

Developer Daniel Avila shared his personal decision matrix for selecting AI models and determining task effort levels in light of the release of Claude Sonnet 5 and the return of Claude Fable 5. While he notes the shared matrix is a high-level summary, his actual development workflows involve more sophisticated custom skills, subagents, and agentic loops.

// ANALYSIS

The launch of Sonnet 5 and return of Fable 5 mark a transition where developers must actively orchestrate multiple models based on cost and reasoning requirements.

* Sonnet 5 serves as a cost-effective workhorse for autonomous agentic loops and routine coding tasks.

* Fable 5's return restores a high-intelligence tier for complex reasoning and advanced software engineering.

* Modern developer workflows are moving beyond single prompts to complex multi-agent architectures and custom execution loops.
