Strata update lets Codex CLI use a 125-billion-parameter AI model running on a home PC

Strata is software that runs AI models locally. It uses a compressed model and draws on the graphics card, CPU, system memory and storage. It supports Windows and Linux.

The update adds an interface that lets Codex CLI send requests to Strata. Qwen3.8-Flash-Next supplies the model responses, while Codex handles tool calls and returns their results to the model. In the v0.1.39 release notes, the maintainer reports testing this loop.

The reference PC has an RTX 5070 with 12 GB of video memory and 64 GB of RAM. The model does not fit entirely in the graphics card’s memory.

Developers can use a familiar coding interface while keeping model requests on their own machine. Tools can still make network calls, so a local model does not make every task offline.
