Fable 5 orchestrates subagents via Composer 2.5 Fast

Hot take: Multi-agent tiering with Fable 5 as the orchestrator and Composer 2.5 Fast as the executor represents the future of software engineering agents, balancing high-reasoning intelligence with low-latency, cost-effective execution.

* The Power of Delegation: Using a Mythos-class model like Fable 5 solely for high-level orchestration prevents attention dilution and context bloat, making long-running tasks far more reliable.

* Model Tiering is the Future: By offloading token-heavy execution tasks to Composer 2.5 Fast, developers can maintain a fast inner loop without sacrificing the top-tier reasoning capabilities of Fable 5.

* Token Burn vs. Latency: While Composer 2.5 Fast is optimized for speed, users must monitor the high billing rate of Fast tokens when subagents spawn aggressively under automated orchestration loops.
