Comparisons of Medium Open Source AI Models (40B-150B)
Open source AI models with between 40 to 150 billion parameters. Models are considered Open Source (also commonly referred to as open weights) where their weights are accessible to download. This allows self-hosting on your own infrastructure and enables customizing the model such as through fine-tuning. Click on any model to see detailed metrics. For more details including relating to our methodology, see our FAQs.
gpt-oss-120B (high) and 
Llama Nemotron Super 49B v1.5 (Reasoning) are the highest intelligence Medium open source models, defined as those with 40B-150B parameters, followed by 
GLM-4.5-Air & Llama 3.3 Nemotron Super 49B Reasoning.
