The Glean model hub provides secure and easy access to a variety of large language models (LLMs), both commercial and open-source, for use with the Glean platform. Users can pick and choose models for their agents and each step in an agentic workflow without needing technical expertise or engineering resources.
What is the Model Hub?
The Model Hub offers over 15 leading open source and proprietary models from providers like OpenAI, Google, Anthropic, Amazon, and Meta.
Flexible Key Options:
- Glean Universal Model Key (formerly Glean Key): Access pre-procured and managed models. Glean handles model provider agreements to ensure your data is never retained or used for model training.
- Customer Key: Use your existing model keys for LLM providers in Glean
Supported Models for Glean Agents
We provide a wide range of models for Glean Agents that are categorized into Basic, Standard, and Premium based on their reasoning capabilities and overall cost to run.
With Enterprise Flex, each agent run uses FlexCredits that are determined by the complexity of an agent including how many data sources it searches, how many steps it takes, how much memory it maintains, how many actions it executes, and the model used for each step. Agents that use higher-tiered models will consume more credits than agents that use lower-tiered models.
