Drew Breunig reflects on how the release of Fable changed his team's approach to AI-assisted coding, making investment in coding harnesses and context strategies worthwhile again. However, due to Fable's high cost, they adopted a tiered strategy, reserving Fable for complex work while using cheaper alternatives like Opus, 5.6, K3, and GLM for routine code tasks.
Background
Drew Breunig is a developer at Fable, an AI coding tool. The quote comes from his essay 'Fable & The End of the Free Lunch,' discussing how the AI model landscape has shifted from assuming cheaper/better models would always arrive to needing strategic model selection based on cost and capability.
