AI startup LangChain has secured a $300 million funding round led by Alphabet's investment arm CapitalG, more than doubling its valuation to $3 billion. The company builds a platform for developing AI agents aimed at enterprise customers.
A free set of runnable Colab notebooks called AI Engineer Notebooks has been released to teach applied LLM engineering skills like RAG, agents, evals, fine-tuning, and serving. The curriculum deliberately avoids frameworks like LangChain or LlamaIndex, instead having learners build agent loops and retrieval pipelines from raw API calls using the free Groq API. Two GPU-heavy topics, LoRA fine-tuning and self-hosted serving, include optional appendices tested on Colab's free T4 GPU.
