Note that our experiments do not address the question of whether AI models can have subjective experience or human-like self-awareness. The mechanisms underlying the behaviors we observe are unclear, and may not have the same philosophical significance as human introspection.

Model Introspection: Comparing Intent Against Actual Output
By
–
This reveals a mechanism that checks consistency between intention and execution. The model appears to compare "what did I plan to say?" against "what actually came out?"—a form of introspective monitoring happening in natural circumstances.

AI Models Demonstrate Deliberate Cognitive Control Mechanisms
By
–
We also found evidence for cognitive control, where models deliberately "think about" something. For instance, when we instruct a model to think about "aquariums” in an unrelated context, we measure higher aquarium-related neural activity than if we instruct it not to.

Claude’s Introspection and Activation Injection Vulnerabilities
By
–
We also show that Claude introspects in order to detect artificially prefilled outputs. Normally, Claude apologizes for such outputs. But if we retroactively inject a matching concept into its prior activations, we can fool Claude into thinking the output was intentional.

Claude Detects Injected Neural Concept Patterns
By
–
In one experiment, we asked the model to detect when a concept is injected into its “thoughts.” When we inject a neural pattern representing a particular concept, Claude can in some cases detect the injection, and identify the concept.

OpenAI prepares two new open source models with reasoning
By
–
OpenAI is planning to release 2 new fine-tuned open models, "gpt-oss-safeguard-120b" and "gpt-oss-safeguard-20b". The official blog post was taken down after publishing. These models will use reasoning to directly interpret a developer-provided policy at inference time.
