It supports QLoRA and LoRA training for Llama, Mistral, Gemma, and other models with minimal code changes. Targeted at ML engineers and researchers who want to fine-tune large models on consumer or budget GPUs.
Train an AI model on your schema and query data in plain English
Vanna.ai is an open-source Python framework that lets you fine-tune a retrieval-augmented LLM on your own database schema and query history. It translates natural language questions into accurate SQL and can run in a notebook or Slack bot. Designed for data teams who need a customizable, private text-to-SQL solution.
AI fine-tuning and dataset curation platform for custom models
Kiln is a platform for fine-tuning large language models and managing training datasets with a collaborative, visual interface. Teams can curate examples, run fine-tuning jobs, and compare model versions to improve task-specific performance. Built for ML teams and product engineers who want to customize models without deep infrastructure expertise.
Learn to build an LLM from the ground up with hands-on code
This Manning Publications book by Sebastian Raschka guides readers through building a GPT-style large language model from scratch using Python and PyTorch. It covers tokenization, transformer architecture, pre-training, and fine-tuning with clear, step-by-step code examples. The book is designed for ML practitioners and engineers who want a deep, practical understanding of how modern LLMs like ChatGPT actually work under the hood.
Hands-on guide to building reasoning-capable AI models step by step
This Manning Publications book teaches readers how to construct reasoning-focused AI models inspired by systems like OpenAI's o1, covering chain-of-thought training, reinforcement learning from human feedback, and search-augmented inference. It provides practical code implementations alongside the theory to help readers understand how deliberative reasoning emerges in modern LLMs. The book is suited for ML engineers and researchers looking to go beyond standard instruction fine-tuning.
Open-source LLMOps platform for prompt engineering and evaluation
Agenta is an open-source platform for building, versioning, and evaluating LLM applications with a focus on prompt engineering workflows. It provides a playground for testing prompts, A/B comparison, human evaluation tools, and deployment pipelines. Suited for AI engineers and product teams who need a structured approach to iterating on LLM-powered features.
Open platform for building and deploying customizable AI agents
AgentDock is an open-source framework for building, configuring, and deploying AI agents with modular tool integrations. It supports connecting agents to APIs, databases, and custom logic nodes through a visual and code-first interface. Designed for developers who want full control over agent architecture and tool orchestration.
AI pair programmer that edits your codebase from the terminal
aider is an open-source command-line tool that lets developers pair-program with GPT-4, Claude, and other LLMs directly in their terminal. It reads repo context, applies multi-file edits, and commits changes with meaningful messages automatically. Best suited for developers who prefer a CLI-first, git-integrated AI coding workflow.
