The open-source AI lab adds OpenAI's latest model family to its agent framework, giving subscribers access to three new variants through a single platform
Nous Research has added GPT-5.6 support to its Hermes Agent, available now through the Nous Portal.
Hermes Agent was not built to be a simple chatbot wrapper. Launched in February 2026, it was designed around persistent memory and skill generation, meaning the system can carry context across sessions and build new capabilities as it operates.
What GPT-5.6 actually brings to the table #
OpenAI’s GPT-5.6 family entered limited preview on June 26, 2026, and it is not a single model. It comes in three variants: Sol, the flagship; Terra, the balanced middle option; and Luna, the fast and cost-efficient tier.
Hermes Agent’s Tool Gateway feature allows it to route tasks to external services, and its native desktop applications mean users are not locked into a browser-based workflow. Pairing those features with a model family that scales from cheap-and-fast to expensive-and-thorough lets developers match compute spend to task complexity.
The GPT-5.6 family is positioned around multi-step task handling, with particular strengths in coding and cybersecurity applications.
The Nous Portal’s growing model library #
The Nous Portal now offers access to over 400 AI models, handling subscription management, billing, and tool integrations like web browsing and image processing through a single interface.
