It can be helpful to pinpoint the in-context information that a language model uses when generating content (is it using provided documents? or its own intermediate thoughts?). We present Attribution with Attention (AT2), a method for doing so efficiently and reliably! (1/8)

You can find the full blog here: blog.langchain.dev/how-to-th… You can find a spreadsheet comparing agent frameworks here: docs.google.com/spreadsheets… I tried to be as specific and nuanced as possible. I would love any feedback!

How to think about agent frameworks

Learn to build reliable AI agents. Compare workflows vs agents, declarative vs imperative approaches, and why context control matters most.

🕸️Better stack traces in latest LangGraph Python! We've done some work to remove internal frames from the stack traces when there is an error in your graph's nodes or edges. This makes it easier to find the error in your code without distractions
