Models and parameters
How MCP clients discover current model IDs, defaults, constraints, and cost-driving parameters.
Model availability changes faster than a static documentation page. Before
setting model, read the generation tool's input schema from MCP tools/list.
Its enum, description, default, compatible modes, resolutions, durations, and
other limits are authoritative.
Omit model to use Advibly's current default. Pin a model only when the
workflow depends on a capability or visual character unique to that model.
Select a model only when necessary
- Read the target tool's live schema.
- Omit
modelfor the current default unless the job requires a named capability such as edit mode, a specific duration, or a particular output resolution. - Validate the whole combination—model, mode, duration, aspect ratio, resolution, and references—against the same schema.
- Render a cheap proof before raising quality, resolution, duration, or the number of outputs.
Selection is complete when every requested parameter is accepted by one model without relying on clamping or an undocumented fallback.
Image generation
advibly_generate_image exposes the current image-model enum. The main
cost-driving parameters are:
| Parameter | Effect |
|---|---|
resolution | Higher output dimensions cost more. |
quality | Model-specific quality tier; upper tiers can cost several times more. |
num_images | Generates and bills for each requested image. |
reference_image_urls | Switches supported models into reference/edit mode. |
on_brand | Attaches brand identity references when true. |
Use medium quality while exploring and raise it only for a final asset when
the selected model supports that value.
Video generation
advibly_generate_video exposes each current video model plus the allowed
mode, duration, resolution, and media-reference fields. Video is normally
priced by output duration and capability tier; resolution and model choice can
multiply the result.
Different models support different combinations. Do not copy a resolution or mode from one model to another without checking the live schema.
When a video setting fails repeatedly, return to the default model and one of its documented combinations, then reintroduce one override at a time.
Talking actors and audio
advibly_generate_talking_videolists its current engines, actors, supported resolutions, and duration rules.advibly_generate_voiceoverandadvibly_generate_musicexpose their current voices, models, and length constraints through their schemas.advibly_list_actorsreturns the actor IDs accepted by talking-video calls.
Fixed and utility operations
Operations such as video analysis, stitching, subtitles, and composition
rendering have their own schemas and pricing behavior. Use the tool description
returned by tools/list, then check Credit costs
before a large workflow.
