# Open Model

OLMo 2 is the latest fully open language model launched by Ai2, available in both 7B and 13B parameter sizes, trained on a massive dataset of 5T tokens. These models perform comparably or even better than other fully open models of similar size and compete with open-weight models like Llama 3.1 on English academic benchmarks. The development of OLMo 2 emphasizes stability during model training, staged training interventions, cutting-edge post-training techniques, and an actionable evaluation framework. These technologies enable OLMo 2 to excel across multiple tasks, particularly in knowledge recall, common sense, and both general and mathematical reasoning.

Llama-3[8B] Meditron V1.0 is an 8 billion parameter large language model (LLM) designed specifically for the biomedical field, fine-tuned within 24 hours after the release of Llama-3 by Meta. The model exceeds all existing open models at the same parameter level in standard benchmarks such as MedQA and MedMCQA, and approaches the performance of the leading open model in the medical field with 70 billion parameters, Llama-2[70B]-Meditron. This work demonstrates the innovative potential of open foundational models and is part of a broader initiative to ensure fair access to this technology in resource-poor areas.

Google Gemma is a cutting-edge lightweight open model developed by Google. It comes in 2B and 7B parameter versions, including base and fine-tuned versions. Built using Google's leading technology in base techniques and instruction tuning, Gemma adheres to AI principles to ensure safe and reliable use. Optimized for Google Cloud and NVIDIA GPUs, it offers global support.

Gemma is part of Google's series of lightweight and cutting-edge open models, built upon the same research and technology used to create the Gemini model. Developed by Google DeepMind and other Google teams, Gemma is inspired by Gemini and releases not only model weights but also tools to foster developer innovation, collaboration, and responsible use of the Gemma model. Gemma boasts exceptional performance and can run directly on developers' laptops or desktops. Designed with responsible AI development in mind, it provides various tools and systems, as well as a toolkit focused on responsible AI generation. Gemma is an open-community product aimed at AI innovation and can be used across diverse applications.
