I Building an LLM Knowledge Graph.

An LLM Wiki is great for organizing knowledge into readable documents — useful for both humans and AI.

But the next step is turning it into an LLM Knowledge Graph: connecting concepts, relationships, sources, evidence, and reasoning paths.

This helps LLMs move beyond simply “reading documents” toward understanding how knowledge is connected, where it comes from, and how it can be used for retrieval, reasoning, and decision-making.

From LLM Wiki → LLM Knowledge Graph:
not just storing information, but turning knowledge into a structured cognitive network that AI can query, reason over, and build with.

They will take 2%. First, estimate what the valuation for your next funding round is expected to be, then give a discount to the token's value. This allows you to perform the necessary calculations. In my opinion, a valuation of under $30 million for the next round is a opportunity, exceeding $50 million not good.

[Raphaël Dabadie (YC P26) @RaphaelDabadie]

What would you guys do if you were in the batch ? 👀

The fact that @OpenAI GPT wants AI to manage my personal finances makes me a bit uneasy.
