Use 'max_completion_tokens' instead.</code></p> <h4 id="summary-steps-reproduce">Steps to reproduce</h4> <p>1. Add a o1 series chat model using your provider /admin/config/ai/providers<br> 2. Visit /admin/config/ai/explorers/chat_generator<br> 3. Select the o1 series module you just added, on the provider configuration<br> 4. Add a message and click "Ask the AI"</p> <p>I used the azure provider from Microsoft Azure AI module, to create the chat model o4-mini.</p>
