what if the AI didn't just learn to do the task better — what if it rewrote the part of itself that decides how to learn, and then rewrote that too. hyperagents are self-referential programs where the task agent (does the thing) and the meta agent (improves the thing) are folded into one editable blob of code. crucially, the meta-level improvement process is itself editable. so the system isn't just learning — it's learning how to learn how to learn. and somehow, it actually works.

§2key findings
  • hyperagents fold task agent and meta agent into a single editable program — the system can rewrite both how it solves problems and how it improves itself
  • the meta-modification procedure is itself editable: genuine recursive self-improvement, not just fine-tuning on feedback loops
  • extends the Darwin Gödel Machine, dropping the domain-specific alignment assumption — theoretically self-improvable on any computable task
  • outperforms baselines without self-improvement across diverse domains: coding benchmarks, robotics reward design, paper review pipelines
  • emergent engineering tools appeared without explicit instruction — persistent memory and performance tracking were invented by the improvement loop, not the researchers
  • meta-level gains transfer across domains and stack across runs: improvements compound rather than reset

the task agent attempts the problem and produces an output. its performance is scored and logged for the meta agent to read.
