LLM FINE-TUNING adapt pre-trained models to your specific tasks and domains. Unsloth @unslothai - fine-tune LLMs faster using significantly less memory Axolotl - flexible post-training pipeline for open models LLaMA-Factory - streamlined fine-tuning for LLaMA-based models PEFT @huggingface - parameter-efficient fine-tuning to cut resource needs TRL @huggingface - reinforcement learning from human feedback (RLHF) Transformers @huggingface - Hugging Face's core library for pre-trained models DeepSpeed @Microsoft - helps run training jobs across many GPUs 𝛊. LOCAL DEVELOPMENT & SERVING run and serve models locally or self-host your own API. Ollama @ollama - run open-source LLMs locally in a single command LM Studio - desktop GUI for running and testing local models llama.cpp - lightweight inference engine across CPU and GPU LocalAI - self-hosted, OpenAI-compatible API server @LiteLLM - unified gateway for 100 LLM providers vLLM - fast inference and serving engine 𝛋. SAFETY & GUARDRAILS control, constrain, and stress-test your LLM apps before they go live. @guardrailsai - adds structured output validation and safety rails NeMo Guardrails @NVIDIA - NVIDIA's toolkit for programmable LLM conversation controls Garak - automated vulnerability scanner for LLMs DeepTeam - red teaming framework to pressure-test LLM applicationsthat's the full stack. save this thread, and share it with someone building with AI.

Great post from @murillodigital on Data Version Control (DVC) & an intro to DataOps which is 1st in a series of posts [to come] where he'll dig deeper into DVC, DataOps & ML pipelines. murillodigital.com/tech_talk… #DataOps #DevOps #MLOps #DVC #DataVersionControl

Huge kudos to the developers of Data Version Control, who realised that there was a need for git-style version control of data files. Easy to install and add to my collaborative workflow. Cheers! #dvc #dataversioncontrol #python #scientificcomputing

What would you expect to see from a dataset diffing tool? Last Thursday we demo'd a rudimentary view of diffing in Qri Desktop (to come in future releases). Video available here: youtube.com/watch?v=h20sL8ye… #datadiffer #datadiffing #dataversioncontrol #dataversioning #gitfordata
