Harrison Chase	248c297f1b	Sample row in table info for SQLDatabase (#769) (#782) ... The agents usually benefit from understanding what the data looks like to be able to filter effectively. Sending just one row in the table info allows the agent to understand the data before querying and get better results. --------- Co-authored-by: Francisco Ingham <> --------- Co-authored-by: Francisco Ingham <fpingham@gmail.com>	1 year ago

Harrison Chase	985496f4be	Docs refactor (#480) ... Big docs refactor! Motivation is to make it easier for people to find resources they are looking for. To accomplish this, there are now three main sections: - Getting Started: steps for getting started, walking through most core functionality - Modules: these are different modules of functionality that langchain provides. Each part here has a "getting started", "how to", "key concepts" and "reference" section (except in a few select cases where it didnt easily fit). - Use Cases: this is to separate use cases (like summarization, question answering, evaluation, etc) from the modules, and provide a different entry point to the code base. There is also a full reference section, as well as extra resources (glossary, gallery, etc) Co-authored-by: Shreya Rajpal <ShreyaR@users.noreply.github.com>	1 year ago

"Only two kinds of egg-laying mammals are left on the planet today—the duck-billed platypus and the echidna, or spiny anteater." https://www.scientificamerican.com/article/extreme-monotremes/ 2. "An [Echidna] egg weighs 1.5 to 2 grams (0.05 to 0.07 oz)[[19]](https://en.wikipedia.org/wiki/Echidna#cite_note-19) and is about 1.4 centimetres (0.55 in) long." https://en.wikipedia.org/wiki/Echidna#:~:text=sleep%20is%20suppressed.-,Reproduction,a%20reptile%2Dlike%20egg%20tooth. 3. "A [platypus] lays one to three (usually two) small, leathery eggs (similar to those of reptiles), about 11 mm (7⁄16 in) in diameter and slightly rounder than bird eggs." https://en.wikipedia.org/wiki/Platypus#:~:text=It%20lays%20one%20to%20three,slightly%20rounder%20than%20bird%20eggs. 4. Therefore, an Echidna is the mammal that lays the biggest eggs. cc @hwchase17	2 years ago
