weswinder · x · 2026-08-11
According to a leak via reply, OpenAI previously struggled with pre-training but excelled in post-training. To address this, they initiated a large pre-training effort codenamed Spud, supporting a new family of models: Sol, Terra, and Luna.
Furthermore, the upcoming model (potentially corresponding to Astra) will utilize an even larger pre-training run codenamed Doug.
