Shadow mode first, the dashboard, the agreement check, the cost maths and the limits.https://2796gaurav.github.io/shad0w/blog/game-speed.htmlhttps://2796gaurav.github.io/shad0w/blog/game-speed.html Fri, 09 Oct 2026 09:00:00 +0000shad0w learned snake and Pong from an LLM's answers. Then it raced three System One decision models on an Apple M5 Pro's GPU and a hosted LLM through the same games, with every decision timed. Here is what happened, and the Pong you can play.https://2796gaurav.github.io/shad0w/blog/honest-numbers.htmlhttps://2796gaurav.github.io/shad0w/blog/honest-numbers.html Fri, 09 Oct 2026 09:00:00 +0000We put shad0w in front of a hosted LLM through the official OpenAI client and measured how much shad0w answered, how often it agreed with the LLM, how fast, and where it answered nothing at all.https://2796gaurav.github.io/shad0w/blog/adding-a-category.htmlhttps://2796gaurav.github.io/shad0w/blog/adding-a-category.html Thu, 08 Oct 2026 09:00:00 +0000A trained shortcut and a changing list of options are a dangerous mix.
