Sasha Rush: rival's new release is just a base model, post-training unfinished
srush_nlp · x · 2026-10-16
Sasha Rush (srush) commented on a rival's newly released base model with two takes:
- The release is just the base model with post-training incomplete; their previous model was more of a proof of concept.
- The situation is odd because the team has had full access to the OpenAI codebase for years, but the replication is being done by very good people rather than plain copying.
He finds the whole thing promising but weird, worth a closer read once post-training lands.
