LangChain is a framework for developing applications powered by language models. We believe that the most powerful and differentiated applications will not only call ... | https://langchain.readthedocs.io/en/latest/index.html |
d9a688714afa-1 | Agents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.
Callbacks: It can be difficult to track all t... | https://langchain.readthedocs.io/en/latest/index.html |
d9a688714afa-2 | Extraction: Extract structured information from text.
Summarization: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.
Evaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using lang... | https://langchain.readthedocs.io/en/latest/index.html |
