Latent Space interviews Alex Zhang, an MIT PhD and first author on Recursive Language Models (RLMs), covering GPU kernels and KernelBench, RLMs, 'mismanaged geniuses,' multi-agent swarms, and the idea of harnesses as compositional generalizers. The episode points to concrete signals: Prime Intellect's Prime Agent, described as a self-improving RLM harness using programmatic tool calling, context as a variable, multi-agent messaging, and self-modifiable harness state, was claimed to be first to ~solve ARC-AGI-3 ahead of OpenAI's Astra; and Rulin Shao's Context Language Models (Sep 30, 2026) push the same idea further by learning context policies in model weights with no harness at all. Zhang's framing is that wrapping stronger models in primitive systems leaves capability on the table.

Why: The concrete decision this surfaces for agent builders: if your harness hardcodes how context is assembled, trimmed, and passed between steps, that is the exact layer these researchers argue is underperforming. The pattern to evaluate is context as a variable or file the model edits itself, plus programmatic tool calling and subagent calls instead of fixed orchestration — the episode attributes token efficiency and expressiveness gains to that shift. There is no Malaysia or Southeast Asia angle in this text; treat it purely as an architecture question for what you are building.
