Architecture
Text actions
Text generation, summarisation, and explanation all use the Mistral chat completions API (/v1/chat/completions).
Image generation
Image generation uses Mistral's agent API, which internally uses Black Forest Labs' Flux model. The flow is:
The image generation agent is created once and its ID is cached in Moodle's plugin config via set_config() to avoid hitting API rate limits. If the cached agent is deleted from Mistral Studio, it is automatically recreated on the next request.
Image resolutions
Images are generated using Black Forest Labs' Flux aspect ratio:
| Moodle ratio | Size | Aspect |
| ------------ | --------- | ------ |
| Square | 1024-1024 | 1:1 |
| Landscape | 1792-1024 | 7:4 |
| Portrait | 1024-1792 | 4:7 |
