Claude Haiku 5.5: cost per accepted outcome Conceptual explainer. Original diagram by AgentGrid. Timing mode: audio. Duration: 45.033s. Spoken words below are the approved voiceover cells. Burned-in captions are the shorter on-screen lines. 1 Haiku 5.5 raises a practical question: does a cheaper coding agent make finished work cheaper? 2 Count generation, checking, retries, escalation and your time. Divide by accepted outcomes. Failed attempts stay in the bill. 3 Jev and OpenAI's Decisions API address a related job: returning constrained decisions. Decisions uses GPT-6 Luna. A valid answer shape still does not prove a correct judgment. 4 Try this proposed pipeline: ticket, typed route with a human-review policy, bounded worker, then stronger review. Measure routing mistakes and rework together. 5 This is docs-based analysis for AgentGrid, not a hands-on test. Use AgentGrid to keep the worker, reviewer and their evidence visible.
