How do you train a language model to become a self-adaptive, long-horizon optimization engine for executable trading policy search?

In our new paper, "The Time Value of Evolution," we introduce Lineage-Value Policy Gradients, or LVPG, a new long-horizon RL technique for adaptive evolutionary search.

This is an absolute game changer

I've always believed that intelligence should come from simple, general building blocks that learn their own abstractions directly from raw data; in other words, the bitter lesson. I think we're finally seeing a real step towards AI that can learn from all data.

Language modeling on raw bytes is a microcosm of this ideal, and to me it's a central problem in AI: if we can't build LLMs that learn end-to-end from bytes, how will we handle the rest of the world's data that we understand even less?

Last year we introduced hierarchical networks (H-Nets) as a first step. Our new version finds up to 3-5x efficiency gains in controlled scaling law experiments, and at larger scale matches an open-source model trained on 11T tokens with ~10x less data and compute. The posts below walk through what we found and why we think it works.

New work on programmable cellular automata by @Amidos2006 @utheprodigyn @togelius and myself!

Cellular automata are powerful but painful to author. Rules are a lookup table; neural CAs are more expressive but a black box.

What if each CA rule was just code that you can read?

What happens when a language model doesn't just write code, but dynamically creates its own expert API mid-run?

Instead of evolving individual game levels, our new paper evolves entire generator programs using an LLM as the mutation and crossover operator.
