Two-Model Collaboration: Near-Perfect Performance at Lower Cost

A forwarded post mentions combining Anthropic's most powerful model with OpenAI's new "senior engineer" model: the former drafts proposals and handles edge cases, while the latter writes the implementation. Together, the results are "insanely good".

Citing Anthropic's benchmarks, the author notes this division of labor achieves about 96% of the performance for 46% of the cost. However, they warn that this "free lunch" only lasted a day; once Fable canceled its subscription, all related tokens became individually billable. The author also shared a full setup article and their delegation policy file.
