An unknown multimodal AI model called Union Alpha has emerged with claims of performance comparable to Claude Fable 5.1 and GPT-6 Astra on the Terminal-Bench 4.0 benchmark. The article does not independently validate those claims, and the model’s architecture and parameter count remain undisclosed. Union Alpha is priced at less than $2 per task and is being offered through a one-week free trial on OpenRouter, Cloudflare AI Gateway, and the OpenCode coding agent. It offers a 260,000-token context window and promises not to retain user data for training, features aimed at developers and enterprise users concerned with cost, large code or research contexts, and data handling. The article presents the model’s emergence as a challenge to established providers’ pricing and market position, but says broader user feedback and independent benchmarks are still needed to determine whether its reported performance and economics hold beyond the initial launch period.
