Union Alpha is a multimodal model built for research, coding, and agentic workflows, while delivering frontier-level performance across a broad range of general-purpose tasks. It accepts text and image input with text output, a 262K-token context window, and native tool calling plus structured outputs (response_format). Union Alpha is a stealth (cloaked) model: its provider is not disclosed while it is being evaluated. Capabilities and availability may change without notice.
