Manage which models Agent Zero uses for chat, utility, and embeddings, with support for scoped overrides and reusable presets.
## What It Does
This plugin centralizes model selection and model-related settings for the application. It provides helpers and APIs for:
- selecting chat, utility, and embedding models
- reading and saving model presets
- checking for missing API keys
- allowing optional per-chat model overrides
- resolving config at global, project, agent, and chat scope
## Main Behavior
- **Scoped configuration**
- Reads plugin config through the standard plugin config system with project and agent overrides.
- **Preset management**
- Loads presets from a user file when present and falls back to bundled defaults.
- **Per-chat override**
- Allows a chat context to store a temporary override or preset reference in context data.
- **Model object construction**
- Builds `ModelConfig` objects and the runtime chat, utility, and embedding wrappers used elsewhere in the app.
- Note: Browser model wiring now lives in the `_browser_agent` plugin.
- **API key validation**
- Reports configured providers that still require API keys.
## Key Files
