I'd like a concrete list of "frontier labs", but don't want to exclude newcomers. I'll write a list below, but if there are labs that aren't on the list but plausibly could be considered frontier, I'll make a manifold poll and rule based on the markets decision.
Also please comment if you think I've missed one:
- OpenAI 
- Anthropic 
- Meta 
- Amazon 
- DeepMind/Google 
- DeepSeek 
- Alibaba (NOTE: this used to say Qwen, but Qwen is the name of the model, not the lab) 
- Mistral 
- XAI (Elon musk lab) 
- Nvidia 
- Update 2025-02-07 (PST) (AI summary of creator comment): Preprints Included: - Preprints (e.g., arXiv) count as a valid form of releasing a paper. 
- The focus is on whether the big labs deem that an AI significantly contributed to the paper, rather than on traditional journal criteria.
