OpenAI's GPT-OSS one year on: Will we ever see another open-weight model?
350 days since GPT-OSS – no successor, only safety fine-tunes.
Deep Dive
Nearly a year later, only safeguard fine-tunes have appeared, with no general-purpose base model or successor. Will Kimi, Qwen and GLM force their hand?
Key Points
- GPT-OSS released 350 days ago, with no general-purpose base model successor since.
- Only safety-focused fine-tunes have been provided, not a new open-weight model.
- Competitors Kimi, Qwen, and GLM continue to release capable open-weight alternatives.
Why It Matters
Open-weight models drive research and custom deployment; OpenAI's absence risks stagnating open-source AI progress.
