         <p>We use vLLM to run models, generally with full f16 safetensors. We make sure to use a virtualenv to hold the dependencies.</p>
         <p><strong>Note:</strong> For Hermes, we use an FP8 quant by adamo1139 (adamo1139/Hermes-3-Llama-3.1-8B-FP8-Dynamic), which is optimized for 4090 and 3090 GPUs.</p>
+        <p><strong>Tool Calling:</strong> The <code>--enable-auto-tool-choice</code> and <code>--tool-call-parser hermes</code> flags are required for Hermes 3 to support function calling via the OpenAI-compatible API. Without these flags, tool calling requests will fail.</p>
         <p>We are considering supporting ollama for better quant support.</p>
         <p>Stand up a replica cluster on a new domain.</p>
