## AI 摘要

一个名为 Union Alpha 的隐身模型上线 OpenCode 和 OpenRouter，目前可在两平台零成本运行编程智能体，OpenCode 称免费期持续一周。该模型面向智能体编码构建，支持图像输入和工具调用，上下文 262K tokens、输出最高 131K tokens，提示词不用于模型训练；据基准测试其表现接近 Fable 5 水平，定价对标 GPT-5.6 Terra。

## 正文

A new stealth model went live on OpenCode and OpenRouter!

It currently lets users run coding agents at zero cost on both platforms, and OpenCode says the free period runs for a week.

What's known so far 👀

According to benchmarks, it performs close to Fable 5 level at a price of GPT-5.6 Terra.

The model accepts images alongside text and supports tool calling.

It handles 262K tokens of context and up to 131K tokens of output.

Prompts are kept out of model training, and OpenCode lists a zero-retention policy on its platform.
