On OpenRouter there is a stealth model union-alpha

16 September on the OpenRouter platform a release of a new stealth model called union-alpha took place. Developers position the novelty as a multimodal solution with support for the tool calling function, designed to perform complex applied tasks in real time. The key feature of the model was high performance in the GPQA Diamond benchmark, where it achieved a result of 90.9%. At the moment, the use of the model's API is provided free of charge, making it an accessible tool for integration into existing agency systems. The model has already been tested in workflows related to the automation of processing client requests in social networks and CRM systems. The technical implementation of union-alpha allows for efficient processing of incoming messages and automatic initiation of response actions without human intervention. The integration of the model into the production environment took minimal time, which confirms the readiness of the architecture to perform tasks with high loads. The emergence of such solutions on the OpenRouter platform expands the range of tools for developers working with autonomous AI agents. The absence of a cost for requests at the testing stage allows for large-scale experiments with Reasoning Lock logic and other data processing methods without increasing the infrastructure budget.
