A quoted post argues that frontier companies keep converging toward the same performance and cost profile.

The author points to an eval where the key takeaway is often which method comes in second, since the winner is under the strongest selection pressure.
The quoted example says Anthropic’s plot shows GPT 5.6 Sol pareto-dominating Fable 5 on coding benchmarks.
The broader claim is that once methods are good enough, frontier labs often end up clustering around similar tradeoffs.
