<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>The maxEmbeddingsInput() method returns a hardcoded value of 1024 tokens with a TODO comment </p>
<pre> public function maxEmbeddingsInput($model_id = ''): int { <br> // @todo this is playing safe. Ideally, we should provide real number per model. <br> return 1024; <br> } </pre><p> This has two problems: </p>
<p> 1. Incorrect value: The mistral-embed model supports 8192 tokens, not 1024. This unnecessarily limits text that can be embedded.<br>
2. Not using the $model_id parameter: The method receives a model ID but ignores it. The Mistral API returns max_context_length for each model via the /v1/models endpoint, which should be used to return accurate limits per model.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>0. have ai_provider_mistral module installed and setup<br>
1. Call $provider->maxEmbeddingsInput('mistral-embed')<br>
2. Observe it returns 1024 regardless of model<br>
3. Check Mistral API - mistral-embed actually supports 8192 tokens </p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p> Update the method to dynamically fetch the model's max_context_length from the Mistral API, with fallback to known defaults</p>
<h3 id="summary-remaining-tasks">Remaining tasks</h3>
<p>- Implement dynamic fetching from API<br>
- Add fallback for known models </p>
