Thinking Before Thinking: Scaling Agentic Inference Through Meta-Reasoning

"As agents take on longer and more complex problems, controlling the execution becomes a task in its own right. Each step in the run brings new control choices, like which partial work to build on, whether to start fresh, or when to stop. We introduce agentic meta-reasoning, an inference-time harness..."

Learning Native Reflection in Unified Models with Interleaved Reinforcement Learning

"Unified multimodal models can both look at and render images, so in principle they can repair their own generations: diagnose what an image gets wrong, revise it, observe the result, and diagnose again. Whether a revision helps is known only after it is rendered, so the reflection text and the image..."

PSSA: A non-transformer language model written from scratch in Rust

💬 HackerNews Buzz: 32 comments 😐 MID OR MIXED
🎯 Implementation language choice • Architecture evaluation rigor • Transformer scalability limits
💬 "You need to show it" • "Quadratic cost explains high costs associated with LLMs"
🔬 RESEARCH

Distillation Defenses Easily Break After Reinforcement Learning

"Distillation attacks copy the reasoning capabilities of closed-source large language models, allowing bad actors to replicate state-of-the-art performance at low cost. Attackers systematically collect a large volume of frontier model reasoning traces and then train (i.e., "distill") their own models..."

🎯 Revenue justification gap • Job displacement economics • Investment bubble risk
💬 "Nothing else justifies the infra spend" • "Current CapEx growth has already outstripped revenue growth"
🔬 RESEARCH

KV-streams for Efficient Compaction in Agentic Reinforcement Learning

"Scaling the horizon of agentic LLMs is bottlenecked by the need to fit ever longer context traces in GPU memory. Context compaction has been the most popular mechanism to alleviate this issue, keeping GPU memory constant for a given trace. Unfortunately, most compaction strategies rely on prefilling..."

Reinforcing Agentic Creativity in Scientific Ideation with Night Science

"Large language models (LLMs) excel at structured, verifiable tasks, but their low-entropy bias can produce homogeneous and predictable outputs, limiting their utility for open-ended scientific ideation. Effective discovery, however, spans a broader creative spectrum: from structured day science to l..."
🔬 RESEARCH

Failure-Transparent Agents: Benchmarking Post-Failure Reporting in Tool-Using Language Models

"Tool-using agents can fail twice: a required tool can fail, and the agent can then report success without the evidence needed to justify it. Existing benchmarks often entangle this reporting failure with tool selection, recovery, and environment dynamics. We introduce Failure-Transparent Agents (FTA..."
🔬 RESEARCH

TokenCast: Forecasting Token Consumption During LLM Agent Execution

"When a large language model (LLM) agent executes the same task, token consumption can vary by over an order of magnitude across runs. The agent chooses its next steps based on tool feedback and intermediate results, while the growing context steadily inflates the input size of every subsequent call...."
🔬 RESEARCH

Character Training for Risk-Averse Agents

"Risk aversion in resources could prevent misaligned AI agents from causing catastrophic harm. Misaligned but risk-averse agents would tend to favor safer strategies like making deals with humans over riskier strategies like rebelling. We train agents to be risk averse through character training, fin..."
🔬 RESEARCH

Shockingly Simple Self-retrospection Improves Agentic Models Without RL

"People learn not only by repeating successful actions, but also by recounting and explaining their experiences, revising their understanding to guide future behavior. Can a language-model agent improve its future actions by training only on explanations of its own experience? We investigate this que..."

Telescopic Language Models

"One deployed language model must often serve many compute budgets, yet serving each budget still means a separate training or compression run per point. We train a Telescopic Language Model (TLM) to be that continuum: a nested-capacity Transformer supervised by stochastic prefix supervision with a f..."

Correct Answers, Invalid Traces: What Verifiable Grade-School Math Reveals About Chain-of-Thought Traces

"Chain-of-thought traces are widely read as records of how models reach their answers, informing debugging, agent auditing, and claims about reasoning. Testing this interpretation is difficult because natural-language thinking traces are rarely mechanically verifiable. We revisit it in iGSM, a synthe..."

Do LLM Agents Execute the Plans They Declare? From Planning-Mode Declaration to Pattern-Specific Execution
