+### Example usage
+#### Pipeline API
+```js
+import { pipeline } from '@xenova/transformers';
+
+const generator = await pipeline('text-generation', 'Felladrin/onnx-int8-TinyMistral-248M');
+const output =  await generator('Once upon a time,', { add_special_tokens: true, max_new_tokens: 60, repetition_penalty: 1.2});
+console.log(output);
+// 'Once upon a time, the world was in turmoil. The United States had been on an unprecedented hiatus since 1970 and it seemed that America’s role as a global powerhouse would be at risk if we were to continue with our current political system.\n\nThe US has become'

+#### Auto Classes
+```js
+import { AutoModelForCausalLM, AutoTokenizer } from '@xenova/transformers';
+
+const model_path = 'Felladrin/onnx-int8-TinyMistral-248M';
+const model = await AutoModelForCausalLM.from_pretrained(model_path);
+const tokenizer = await AutoTokenizer.from_pretrained(model_path);
+
+const prompt = 'Once upon a time,';
+const { input_ids } = tokenizer(prompt);
+const tokens = await model.generate(input_ids, { max_new_tokens: 60, repetition_penalty: 1.2});
+console.log(tokenizer.decode(tokens[0], { skip_special_tokens: true }));
