Run Goose on Hermes 3 Llama 3.1 405B
Goose is an open-source AI agent that goes beyond code suggestions: it installs dependencies, runs and tests code, and automates whole engineering workflows from the terminal or its desktop app. Created by Block and now part of the Linux Foundation's Agentic AI Foundation alongside MCP, it is built to be model-agnostic. Opper ships in its provider list, so you pick Opper, paste your key, and Goose runs on any of 700+ models with a live model list.
