+# smollm-convo-filler-onnx-official
+
+This is an **official ONNX conversion** of [maximuspowers/smollm-convo-filler](https://huggingface.co/maximuspowers/smollm-convo-filler) using the standard Hugging Face Optimum library for [Transformers.js](https://huggingface.co/docs/transformers.js) compatibility.
+
+## 🔧 Official Conversion Method
+
+This model was converted using the official Hugging Face method:
+
+```python
+from optimum.onnxruntime import ORTModelForCausalLM
+
+ort_model = ORTModelForCausalLM.from_pretrained(
+    "maximuspowers/smollm-convo-filler",
+    export=True,
+    provider="CPUExecutionProvider",
+    use_io_binding=False,
+)
+```
+
+## 🚀 Usage with Transformers.js
+
+```javascript
+import { pipeline } from '@huggingface/transformers';
+
+const chatPipeline = await pipeline(
+  'text-generation',
+  'maximuspowers/smollm-convo-filler-onnx-official',
+  {
+    dtype: 'fp32',
+    progress_callback: (data) => console.log('Loading:', data)
+  }
+);
+
+const result = await chatPipeline('Q: Hello, how are you?\nA:', {
+  max_new_tokens: 50,
+  temperature: 0.7,
+  do_sample: true,
+  repetition_penalty: 1.1,
+  pad_token_id: tokenizer.eos_token_id
+});
+
+console.log(result[0].generated_text);
+```
+
+## 🔗 Usage with Vercel AI SDK
+
+```javascript
+import { transformers } from '@ai-sdk/transformers';
+
+const model = transformers('maximuspowers/smollm-convo-filler-onnx-official', {
+  dtype: 'fp32'
+});
+
+const { text } = await generateText({
+  model,
+  prompt: 'Hello, how are you?',
+  maxTokens: 50,
+});
+```
