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.
GooseoninIn Goose (v1.49 or later), run goose configure → Configure Providers → Opper, or in the desktop app open Settings → Models → Configure providers → Opper, then paste your Opper key (stored as OPPER_API_KEY). Then pick Ling-3.0-flash-VL.
Ling-3.0-flash-VL runs on the routes below. Route only to EU providers when your data has to stay in Europe.
Ling-3.0-flash-VL is InclusionAI's native multimodal Ling-3.0-flash, a 124B open-weight Mixture-of-Experts with 5.5B active that reasons over images and video with up to 256K context.
