About Hermes Agent
Hermes Agent is a desktop AI agent developed by Nous Research that maintains persistent memory and self improving capabilities across sessions and platforms. It operates as a local first, cross platform interface for LLMs, integrating with multiple model providers and deployment environments without vendor lock in. The agent implements a closed learning loop where it curates its own memory, creates and refines skills from experience, and supports cross session recall via full text search and summarization.

About GPTCache
GPTCache is an MIT licensed Python library that builds a semantic cache for large language model queries, letting applications built on ChatGPT and other LLMs answer repeated or semantically similar prompts from a local cache instead of issuing a fresh, billable API call each time.
