OpenAI's Next Model Codenamed Doug, Largest Pretraining Run Planned by Year-End
Recent reports from multiple tech bloggers claim OpenAI plans to launch its largest pretraining run ever by year-end, with the model internally codenamed 'Doug'. It is said Doug's capabilities will make current versions (like Fable) look primitive, and GPT-5.5 is not the last major pretraining, with GPT-6 to follow. Additionally, GPT-4.5 was deprecated just months after release due to high API serving costs.
Confirmed
- SemiAnalysis indeed mentioned the codename 'Doug' in their July 9 paid newsletter, predating recent discussions about another codename 'Astra'.
- According to a leaker, GPT-4.5 was a successful large pretraining model but was deprecated months after release due to high API serving costs.
Unconfirmed
- The exact relationship and iteration order between Doug and Astra remain unclear. There is confusion in the community, with some speculating Doug is a brand-new pretraining model after Astra, but since its codename surfaced earlier than Astra, the actual connection is still a mystery.
- The plan for OpenAI to start its largest pretraining run by year-end and later release GPT-6 is currently only based on rumors from tech bloggers and leakers (e.g., ChrisGPT), with no official confirmation. VraserX also noted that combining such compute with continual learning techniques like SEAL could yield models far beyond GPT-6, but this remains speculative.
- Another tweet (m8) mentioned OpenAI had started a large pretraining project called Spud to support new model families like Sol, Terra, and Luna, but its relation to Doug is unclear and not corroborated by other sources.
Why it matters
- If the rumors about 'Doug' and the largest pretraining run are true, it means OpenAI's next-generation models will achieve a leap in capability, further widening the industry gap. The discussion about codename origins also reflects high external interest in OpenAI's product roadmap.
