Open models
Open models provide pretrained capabilities for various AI tasks, including Gemini models that excel in multimodal processing. You can use open models with Vertex AI. An open model is freely available, you are free to publish its outputs, and it can be used anywhere provided you adhere to its licensing terms.
When you use an open model with Vertex AI, you use Vertex AI for your infrastructure. You can also use open models with other infrastructure products, such as PyTorch or Jax.
Open weight models
Many open models are considered open weight large language models (LLMs). Open models provide more transparency than models that aren't open weight. A model's weights are the numerical values stored in the model's neural network architecture that represent learned patterns and relationships from the data a model is trained on. The pretrained parameters, or weights, of open weight models are released. You can use an open weight model for inference and tuning while details such as the original dataset, model architecture, and training code aren't provided.
Open source models
Open models differ from open source AI models. While open models often expose the weights and the core numerical representation of learned patterns, they don't necessarily provide the full source code or training details. Providing weights offers a level of AI model transparency, allowing you to understand the model's capabilities without needing to build it yourself.
Use open models in Vertex AI Model Garden
Details about an open model and how to use it are on its model card in Model Garden. To access the model card of an open model, go to Model Garden and search for its name. For more information about Model Garden, see Explore AI models in Model Garden.
