Analysis of Qwen3.6-35B-A3B shows that ablating 92.2% of weak neuron activations causes minimal performance loss, proving neurons are tractable units of analysis.
Researchers argue for maintaining multiple plausible AI-generated models to identify where predictions disagree and guide future experiments.
Researchers demonstrate that removing a single vector from the residual stream of 13 open-source models up to 72B parameters effectively disables refusal mechanisms.
MIT CSAIL researchers demonstrate that GPT-6 Astra can read and write neural network weights, improving Qwen3.5-0.8B's MATH-500 score from 7.9% to 48.1% by editing 0.016% of its parameters to fix reasoning loops.
Routing transplant experiments on OLMoE and DeepSeek models show that forcing morality-associated expert paths significantly alters malicious code detection accuracy, independent of the model's readable workspace.
A NeurIPS 2026 study finds that 7 of 8 tested LLMs flip correct answers 45-88% of the time when misinformation is attributed to a verified source, even if they resist the same misinformation from users.
Goodfire identifies interpretability as the key bottleneck for AI alignment and proposes a roadmap involving activation monitoring and intentional design.
Analysis of public logs from the Emergence World preprint shows LLM agents develop shared shorthand and semantic extensions, but no new grammatical structures or intentional concealment.
The Goodfire research team has released Activation probe technology that utilizes internal model Activation signals to detect Reward Hacking and reduce monitoring costs.
A new study demonstrates that neural network vector representations can be approximated by symbolic structures.
The paper and code for 'Spectral Neuron', a new ML model combining scalability and interpretability, have been released.
A position paper from ICML 2026 warns that interpreting LLM intermediate tokens as human thought processes is dangerous.
Experimental results suggest that LLMs can partially detect and regulate their internal states.
Mathematical logic proves that no specific direction in an LLM's embedding space can represent Truth.
Anthropic has open-sourced Jacobian Lens, a tool that interprets activations in the middle layers of LLMs as vocabulary tokens.
LG AI Research introduces the latest research trends in foundation models presented at ICLR 2024, focused on interpretability, sustainability, and safety.
Goodfire unveiled the beta of its Silico platform, which automates AI research experiments.
Anthropic has unveiled a technique for monitoring a model's decision-making process through its internal activation space (J-space).
This covers the latest research trends and limitations in understanding the internal reasoning mechanisms of LLMs.
Anthropic has discovered 'J-space,' where LLMs internally form concepts before generating language.
Through the Jacobian Lens technique, the region where an LLM's conscious reasoning occurs, called J-Space, was identified.
It has been revealed that LLM safety alignment is not distributed across the entire model but is concentrated in specific neurons, meaning that manipulating just a single neuron can disable safety guardrails.
This work proposes APM models that learn internal safety policies from data annotators' labeling behavior and analyze the causes of disagreement.
MemoryLLM proposes separating the FFN from Self-Attention in Transformers and using it as a context-free, token-level neural retrieval memory.
