It’s worth highlighting Ai2’s work on building a fully Open Source AI. It seems to adhere to the OSAID: > **[Ai2 releases Tülu 3, a fully open-source model that bests DeepSeek v3, GPT-4o...](https://venturebeat.com/ai/ai2-releases-tulu-3-a-fully-open-source-model-that-bests-deepseek-v3-gpt-4o-with-novel-post-training-approach/)** > > DeepSeek-R1 released model code and pre-trained weights but not training data. Ai2 is taking a different approach to be more open. > What makes Tülu 3 405B different for users, though, is how Ai2 has made the model available. > There is a lot of noise in the AI market about open source. DeepSeek says its model is open-source, and so is Meta’s Llama 3.1, which Tülu 3 405B also outperforms. > With both DeepSeek and Llama the models are freely available for use; and some code, but not all, is available. > For example, DeepSeek-R1 has released its model code and pre-trained weights but not the training data. Ai2 is taking a different approach in an attempt to be more open. > “We don’t leverage any closed datasets,” Hajishirzi said. “As with our first Tülu 3 release in November 2024, we are releasing all of the infrastructure code.” > She added that Ai2’s fully open approach, which includes data, training code and models, ensures users can easily customize their pipeline for everything from data selection through evaluation.
