🔁 Repetitions in LangSmith 🔁 You can now run multiple repetitions of your experiment in LangSmith. This helps smooth out noise from variability introduced by your application or from your LLM-as-a-judge evaluator, so you can build confidence in the results of your experiment. In the video below, learn how to evaluate on a dataset using repetitions. You can check the mean score across N repetitions, and also compare the outputs for variability across repetitions. 📽️ Video: https://lnkd.in/gFRGPAv5 📓 Evaluate on a dataset with repetitions: https://lnkd.in/gP-Mt_Hh 🌟 Try it out in LangSmith: smith.langchain.com

🌀Self-correcting code assistants with Codestral 🌀 Mistral AI just released Codestral-22B, a top-performing open-weights code generation model trained on 80+ programming languages with diverse capabilities (e.g., instructions, fill-in-the-middle) and tool use. Of course, we had to test it out! In the video below, we show how to build a self-corrective coding assistant using Codestral with LangGraph. Using ideas borrowed from the AlphaCodium paper, we show how to use Codestral with structured output / tool use, unit testing in-the-loop, and error feedback to self-correct from mistakes. 📽️ Watch the video: https://lnkd.in/gPpCwF5d 📓 Code added to our Mistral AI recipes: https://lnkd.in/g9ByxuVh 🗣️ Codestral blog post: https://lnkd.in/gB-ahVWr

Semantic search is great for extracting meaning, and Qdrant’s filters make it even better for specific searches! Here's how to effectively narrow search results and dynamically generate and execute queries in real time with the innovative self-querying retriever in LangChain. In this tutorial, Daniel Romero shows you: ▶️ When to use semantic search or directed lookups. ▶️ Detailed walkthrough on handling a large dataset of 130k wine reviews in Qdrant. ▶️ How to perform semantic searches and apply precise filters based on metadata like country, price, and rating to refine results. ▶️ The new concept of a self-querying retriever in LangChain that combines natural language queries with structured data filtering. 🎥 Watch the full video here! 👇 https://buff.ly/4bQSIXK Learn more about Qdrant filtering: https://buff.ly/3V0I3mi

✂️ Dataset Splits ✂️ With dataset splits, it's now easier to run evaluations on a subset of your dataset in LangSmith. You can tag examples with different split names, edit and add to splits, and filter on your desired criteria. Splits can come in handy when have a dataset with multiple categories that you'd like to evaluate separately. Split datasets also allow you to test new use cases that you may want to include in a dataset and evaluate in the future — by first adding examples to a separate set to test, while preserving your evaluation workflow. 📽️ See a video example: https://lnkd.in/gqb4znMj 📓 Create/manage dataset splits: https://lnkd.in/gQBWZGgZ 📓 Evaluate on a dataset split: https://lnkd.in/g7WcFWCU 🌟 Try it out in LangSmith: https://lnkd.in/gbbj5tf5
