What I find most interesting about agents is how much freedom they have inside a fixed compute budget. Give an agent a goal and it can write code, search the web, and operate a computer in ways you never prescribed. The moment it became real for me was using coding agents to build a macOS transcription app in Swift, a language I had never used. That left me wondering, which problems benefit most from giving agents this much freedom? I think recursive self-improvement sits at the far end of this spectrum, where agents edit and optimize their own code. It works well when the task has a deterministic verifier, like software engineering and unit tests. It gets harder for open-ended tasks like writing papers or natural-language proofs, where evaluation relies on model-based judges. Agents can exploit weaknesses in those judges, creating an alignment gap between what earns a high score and what people actually value. For the past three months, I’ve had the privilege of working on this problem with @Alex__Iacob, @itsmaddox_j, @williamfshen, @niclane7, and a team spanning @Cambridge_Uni, @NVIDIAHealth, @flwrlabs, @mbzuai, and @Inria. We recently released the Red Queen Gödel Machine, which co-evolves agents with their evaluators. It reached a 71.7% coding pass rate versus 69.9% for the prior baseline using 1.35–1.72× fewer tokens, produced paper writers accepted 1.78–1.86× more often by a reviewer panel, and improved proof-grading accuracy from 70% to 76%. I also led experiments with @NickVenanzi using Nemotron 3 Ultra for search-time worker agents and GPT-5.5 for the meta-agent. On paper review, this approached the GPT-5.5-only result at roughly 13× lower price-equivalent search-token cost. Read the paper: arxiv.org/abs/2606.26294
