Union Alpha on OpenRouter: Tests and Reviews

A demo of the union-crew repo has Union Alpha dispatch DeepSeek V4.1 Flash subagents to run low-cost agent workflows and work around GPT-6 usage limits.

Someone matches GLM-5.5 rumors of 3T+ parameters and 1M token context against the anonymous Union Alpha model in OpenCode and asks whether they are the same.

The author used a Union Alpha 3D game recording as a prompt to rebuild the game in Antigravity with Gemini and in Cursor with Grok 4.6, where Grok won, after Cline with OpenRouter failed to use Union Alpha.

The author used Union Alpha to generate a 3D moon with gold cracks and a shattered star ring in one pass, and says the model is a scheduling alliance of Llama, Qwen, GLM and DeepSeek.

A demo shows running Union Alpha in OpenCode via the union-crew repo, handing subtasks to DeepSeek V4.1 Flash subagents to cut costs.

A long post walks through the reveal: Pareto has several open and frontier models work the same task and check each other, calling a stronger model when needed; the team says there was no new training run, and the free preview ended after traffic hit billions of tokens per minute.

The author confirms Union Alpha was not Kimi K3 or any single model but a model router priced at about a quarter of Fable/Astra, and says it performs well.

A post lists a guessed breakdown for Pareto 26.9: Llama 3.3 70B and Qwen 3.6 for easy tasks, GLM 5.3 Flash for coding, DeepSeek V4 Flash as judge, and GPT 6 Astra for hard tasks.

The author, initially skeptical of Hermes' multi-model theory, says Cloudflare documentation confirms Union Alpha was a routing system called Pareto 26.9, and laments that the stealth phase ended so quickly.

A Chinese user tested Union Alpha on tasks like a pelican riding a bicycle and found results random, with completion times ranging from one minute to half an hour, suggesting it suits only short tasks.

Running a standard shooter prompt on Union Alpha, the stealth model on OpenRouter, produced a fully playable FPS whose menu matches GPT-6 Astra's signature title, orange button and dark 3D scene.

An eight-item tech brief notes that the anonymous model Union Alpha landed on OpenRouter and processed about 2 billion tokens on its first day, with a 260K context window, multimodal input, tool calling and free blind testing.
