Chain-of-thought reasoning

Technique in which a language model writes intermediate steps as tokens before its final answer, placing its reasoning in the context window.

NVIDIA's 3D CT model leaves clinical validation to whoever post-trains it

NV-Reason-CT reads a 300-to-600-slice study as a single 3D volume instead of a stack of frames. NVIDIA published it as an uncleared research foundation whose cited multireader study measured its chest X-ray predecessor.

A small model solved nearly three in ten ARC-AGI-1 puzzles without writing out its steps

BDH-CQ updates a fixed-size internal memory instead of generating chain-of-thought tokens, and its authors put a single puzzle query at about $0.00070. Two outside researchers say the result does not yet credit the design.

Researchers Show Encrypted Reasoning Blocks From OpenAI, Anthropic and Google Can Be Decrypted Using a Weaker Sibling Model

A dev.to writeup credits researchers with decrypting 10,000 reasoning traces from OpenAI, Anthropic and Google models for about $720, and the storage question behind that claim sits in the API example the post itself prints.

Anthropic's faithfulness test caught Claude naming a planted hint only a quarter of the time

Anthropic tested whether a model's visible reasoning names what actually drove its answer, and for two reasoning models it usually did not. Teams treating traces as an audit record are relying on that property.

A recurrent block unrolls a 3.5B model into a 50B-parameter compute bill

Geiping's Huginn improves on reasoning benchmarks by looping a latent block instead of emitting chain-of-thought tokens, holding weights at 3.5 billion while per-token compute rises about fourteenfold.
