Claude distillation has been a big topic this week while I am (coincidentally) writing Chapter 8 on model distillation. In that context, I shared some utilities to generate distillation data from all sorts of open-weight models via OpenRouter and Ollama:

Excited to be launching a series of short videos (5 min or less) to optimize the training performance of your PyTorch models! Covering - mixed-precision training - multi-GPU training strategies - Compiling PyTorch models - and finding good batch sizes 🔗

When doing machine learning and AI research (or writing books), making the code reproducible is usually desirable. Often, that's easier said than done! So, I recorded a video illustrating and dealing with 6 sources of randomness that occur when training deep neural networks and LLMs: 1. Model weight initialization 2. Dataset sampling and shuffling 3. Nondeterministic algorithms 4. Different runtime algorithms 5. Hardware and drivers 6. Randomness in generative AI models

$I just added the new Llama 3.2 1B and 3B models to LitGPT, the open-source LLM library I help develop (focused on efficiency and code readability). LitGPT allows you to fine-tune and use these models on the cloud or a laptop. So, if you are looking for something to play with this weekend: # 1) Finetune the model litgpt finetune_lora meta-llama/Llama-3.2-1B \ --data JSON \ --data.json_path my_custom_dataset.json \ --train.epochs 1 \ --out_dir out/llama-3.2-finetuned \ --precision bf16-true # 2) Chat with the model litgpt chat out/llama-3.2-finetuned/final # 3) Serve the model via an API endpoint litgpt serve out/llama-3.2-finetuned/final$

One of the Lightning 2.0 highlights is the open source Fabric library ( Fabric let's you scale you PyTorch code with only a few lines of code. Used the pre-release for my research & it's amazing! Here's a quick demo + code:

Excited to share Unit 10, the finale of my latest course! 🎉 My aim is to provide a modern take on learning deep learning & AI using open-source libraries. And I hope you enjoyed the journey from backpropagation to implementing LLMs in PyTorch!
