Currently, there is no way to check what input/output types a model supports (e.g. text, audio, image).

Problem

When building features like model selection UIs or validation, developers need to know if a model supports:

• text → text
• audio → text
• text → audio

Right now, this requires guessing based on model names (e.g. transcribe, audio, etc.), which is not reliable.

Expected Solution

Provide a way to access model capabilities, for example:

$model = AiClient::model('gpt-4o');

$model->getCapabilities();

/*
[
  'input' => ['text', 'image'],
  'output' => ['text'],
]
*/

Or simple helpers:

$model->supportsInput('text');
$model->supportsOutput('text');

Why this helps

• Makes model selection safer
• Removes fragile string-based checks
• Helps build better UIs and integrations
