Description
Union Alpha is a stealth AI model optimized for agentic coding, recently released via the OpenCode platform. It achieved a 51% score on Terminal-Bench v4.0 at a cost of approximately $1.5 per task, positioning it on the Pareto frontier near GPT-6 Astra but at a much lower price point. It supports multimodal (image) input and does not train on user data.
