You Don't Need to Run Every Eval

Yuchen Zeng, Dimitris Papailiopoulos

A modern model release reports scores on 40+ benchmarks and the same evaluations were run many more times before it: to track training progress, compare design choices, and select…

SuperThoughts: Reasoning Tokens in Superposition

Zheyang Xiong, Shivam Garg, Max Yu +4

Long Chain-of-Thought (CoT) reasoning improves LLM problem-solving but is computationally expensive due to sequential token generation. While recent works explore reasoning in cont…

ECHO: Terminal Agents Learn World Models for Free

Vaishnavi Shrivastava, Piero Kauffmann, Ahmed Awadallah +1

CLI agents are the closest thing language models have to an embodied setting: the model emits commands, the terminal executes them, and the returned stream -- stdout, errors, files…

Open-World Evaluations for Measuring Frontier AI Capabilities

Sayash Kapoor, Peter Kirgis, Andrew Schwartz +15

Benchmark-based evaluation remains important for tracking frontier AI progress. But it can both overstate and understate deployed capability because it privileges tasks that can be…

MEMENTO: Teaching LLMs to Manage Their Own Context

Vasilis Kontonis, Yuchen Zeng, Shivam Garg +7

Reasoning models think in long, unstructured streams with no mechanism for compressing or organizing their own intermediate state. We introduce MEMENTO: a method that teaches model…

Endless Terminals: Scaling RL Environments for Terminal Agents

Kanishk Gandhi, Shivam Garg, Noah D. Goodman +1

Environments are the bottleneck for self-improving agents. Current terminal benchmarks were built for evaluation, not training; reinforcement learning requires a scalable pipeline,…
