Nonprofit AI research institute Ai2 on Thursday released Olmo 3, the next generation of the Olmo family of open-source models.
The model lineup is Olmo 3-Base, Olmo 3-Think, Olmo 3-Instruct, and Olmo 3-RLZero.
The updated model is the latest fully open release in a market with growing demand for open source generative AI systems that allow customers to more easily and securely fine-tune models to their organization’s specific needs.
Instruct, Think, and RLZero models are built on the Base model. Instruct is a 7B parameter model focused on common chat and tool usage. Olmo 3-Think is the nonprofit lab’s first open facility thinking modelthe parameter sizes are 7B and 32B. The model reveals their thought process. It is valuable for research and education. The base model also comes in two sizes: 7B and 32B. These models focus on text, coding, and math. RLZero is suitable for: reinforcement learning Ai2 says it’s designed to handle difficult reasoning behaviors.
Ai2 has released weights and checkpoints for each training milestone, including pre-training model, in-training model, and post-training checkpoints. This means that the model is completely open source, and not just “open” like popular models in the genre like Meta. llama line.
Commitment to openness
The release of Olmo 3 demonstrates Ai2’s continued commitment. openness.
“They’re just repeating what they think is the ideal,” said Mark Beccue, an analyst at Omdia, a division of Informa TechTarget. “When you talk about openness, they really embrace it.”
He added that Olmo3’s focus on inference shows how Ai2 recognizes the importance of inference in the AI market, especially in the wake of its rapid rise. Agent AI technology.
“Most AI agent functions, more advanced functions, require inference,” Beccue said.
However, although Ai2 is known for its completely open approach and is well known in the research field, it still faces major hurdles in gaining popularity among enterprises as a commercial application.
The challenge of visibility
One reason is that, despite being open source, the vendor’s largest model has 32B parameters, whereas models offered by other open model providers are larger. for example, Metarama 3.1-405B. But Ai2’s latest Olmo models are purpose-built, “so they can be used in certain cases,” Becku said. “They are professional in a way.”
Meta has also built an infrastructure around the Llama model that enables integration with specific tools. Ai2 lacks this kind of infrastructure because it may not have the resources to create it, Becku said.
Despite these obstacles, Ai2 remains a good option for businesses. open source modelMany believe this will help in the safe deployment of AI technology.
“Ai2 sees this as a way to continue to advance the standards that should be expected from models,” Becku said. “AI2 has been nothing more than a research institute that is very rigorous and very direct in its intentions about what it wants. They aim to promote better uses of AI.”
