Union Alpha Is No Longer a Mystery Model and Stopped Being Free Yesterday

The anonymous stealth/union-alpha model on OpenRouter, launched September 16, turned out to be the blended Pareto model from unbiased.ai. The free period was closed early due to a load of 1B tokens per minute; the current Pareto 26.9 costs $2.50 per 1M input and $7.50 per 1M output tokens.

• Union Alpha is unbiased.ai's blended Pareto model, not a standalone one
• Free access closed early due to 1B tokens per minute
• Pareto 26.9: $2.50 per 1M input and $7.50 per 1M output tokens
• Pareto 26.9 does not lead in any benchmark in the table
