🎉 You have realized the way to use GPT-OSS on Google Colab!


WHAT YOU LEARNED:
 ✓ Appropriate mannequin loading (no load_in_4bit - makes use of native MXFP4)
 ✓ Primary inference with correct parameters
 ✓ Configurable reasoning effort (low/medium/excessive)
 ✓ Structured JSON output technology
 ✓ Multi-turn conversations with reminiscence
 ✓ Streaming token technology
 ✓ Perform calling and gear use
 ✓ Batch processing for effectivity
 ✓ Interactive Gradio chatbot


KEY TAKEAWAYS:
 • GPT-OSS makes use of native MXFP4 quantization (do not use bitsandbytes)
 • Really useful: temperature=1.0, top_p=1.0
 • gpt-oss-20b matches on T4 GPU (~16GB VRAM)
 • gpt-oss-120b requires H100/A100 (~80GB VRAM)
 • All the time use trust_remote_code=True


RESOURCES:
 📚 GitHub: 
 📚 Hugging Face: 
 📚 Mannequin Card: 
 📚 Concord Format: 
 📚 Cookbook: 


ALTERNATIVE INFERENCE OPTIONS (for higher efficiency):
 • vLLM: Manufacturing-ready, OpenAI-compatible server
 • Ollama: Straightforward native deployment
 • LM Studio: Desktop GUI software
