Are there any strong LLMs trained without CUDA?
The most interesting one IMO is OLMo from AI2, which is truly open. You can read their blog post about it (https://blog.allenai.org/hello-olmo-a-truly-open-llm-43f7e73...) but basically it is open everything - they released everything you need to reproduce their weights (training data, training code, evaluation code, and weights) with a friendly (Apache) license.
