Models & Research
Coding Agents Can Shrink Language Models While Preserving Most of Their Accuracy — CompressionBench tested whether six coding agents could independently compress three large language models under two storage limits. Of 36 submissions, 29 passed independent checks. The compressed models that best preserved next-token predictions in each setting averaged 77.3% accuracy on math, coding, and trivia questions, compared with 79.6% for the originals. Testing the answers each model generated also revealed errors that its next-token prediction scores missed. arXiv ↗
My takeaway: Coding agents compressed language models end to end, and 29 of 36 submissions passed verification. This makes agent-led compression worth piloting to see whether it lowers serving costs.
Coding Agents Solve More Tasks When a Second Model Chooses Their Next Step — The researchers tested a method in which a coding agent proposes four or eight possible actions at each step, and a second model chooses one to execute. Across 89 command-line tasks, agents solved more tasks, succeeded more consistently across repeated attempts, and used about 40–50% fewer turns. Considering several options at every step came at a cost: the models generated 3.6 to 8.7 times as many tokens per attempt. arXiv ↗
My takeaway: This two-models approach is useful when a higher task success rate justifies the extra inference cost. At each turn, one model processes several next steps, and the other choose one to execute. The effect on completion time depends partly on how many options the system can generate in parallel and how it serves both models. The paper leaves the size of that effect open.
