Investor’s Last Exam: AI's Final Test

Investor’s Last Exam is the benchmark that finally tests whether AI agents can do real equity investment without seeing the future. Instead of just answering questions, these models have to investigate evidence, build forecasts, and make actual investment judgments based only on information available at a specific historical cutoff. It solves the problem of knowing if an AI’s analysis is actually correct or just logically coherent. The most surprising part is that even when models produce perfect, coherent analysis, they still get zero points if their forecasts miss the actual market outcome. This separates real predictive skill from just looking smart.

📦 patch-gg/pixelfx

pixelfx

pixelfx is a library of two hundred and thirty-two pixel art effects, each built entirely from code rather than images. The most surprising part is that it includes a skill for Claude Code that teaches the AI to draft, render, and refine new effects exactly the way a picky pixel artist would. You don't just grab a file; you ask the AI to make a frost nova punchier or export a fire sheet for Godot, and it iterates until the motion looks right.
