Why "best model" is the wrong question now
Software engineering tasks are becoming intelligence-saturated, shifting developer focus from model quality to cost
“the sensitivity of a lot of developers has totally shifted from, wait, I need to be using the best possible model to holy cow, I'm spending so much money on my coding agents”
A LangChain speaker argues that with frontier models like Fable 5 reaching a new capability tier, many routine software engineering tasks are now 'intelligence saturated'—meaning all major models handle them adequately. As a result, developer attention has pivoted from chasing the best model to minimizing inference costs and latency. This reframes the competitive landscape: frontier capability still matters for adversarial or high-stakes workloads, but cost efficiency is the dominant concern for the broad developer market.
