01 · The idea
What stayed with us
Post-training is a system of custom data, reward shaping, performance work, infrastructure, evaluation, and packaging rather than a generic fine-tuning screen.
02 · The local translation
What we did with it
PostTrainLLM was reframed as a Mac-local specialist factory organized around target, data, post-training, evaluation, packaging, and reporting.
03 · The boundary
Where the comparison stops
The positioning was adopted, not Baseten's hosted infrastructure or scale assumptions.
