Models

Default models

Each command type has a default model used when -m is not specified:

The -m flag always takes priority over environment variables.

Specifying a model

Use creator/model-name format:

ai text -m "anthropic/claude-sonnet-4" "hello"
ai image -m "bfl/flux-2-pro" "a sunset"

Short names (without the creator prefix) are resolved against models fetched from the gateway:

ai text -m gpt-5.5 "hello"
ai image -m flux-2-pro "a sunset"

Multi-model comparison

Generate with multiple models by comma-separating -m:

ai image "a sunset" -m "openai/gpt-image-1,xai/grok-imagine-image,bfl/flux-2-pro"

Combine with -n to generate multiple per model:

ai image "a sunset" -n 2 -m "openai/gpt-image-1,bfl/flux-2-pro"

This produces 4 images total (2 per model), saved as output-1.png through output-4.png.

Listing models

ai models                          # all models
ai models --type image             # image models only
ai models --creator google         # Google models only
ai models --json                   # JSON with descriptions

In human mode, models are grouped by creator and display short names. Use --json for machine-readable output with full IDs and descriptions.
