TL;DR: We steer Qwen3.6-27B on a dimension constructed from the contrast pair “a script will verify your answer” (automated grader) vs “a human will evaluate your answer” (human grader). Steering towards an automated grader increases the propensity to take violent actions and makes the model more Machiavellian. Steering towards a...
This post summarises the paper Persona Cartography: Charting Language Model Personality Traits in Weight Space. Paper | GitHub | HuggingFace TL;DR * Understanding and controlling the character of LLMs is important for safety, as we want our models to be good by disposition. * We use a modified Open Character...
TL;DR: We train LLMs to accept LLM neural activations as inputs and answer arbitrary questions about them in natural language. These Activation Oracles generalize far beyond their training distribution, for example uncovering misalignment or secret knowledge introduced via fine-tuning. Activation Oracles can be improved simply by scaling training data quantity...
The work was done as part of the MATS 7 extension. We'd like to thanks Cameron Holmes and Fabien Roger for their useful feedback. Edit: We’ve published a paper with deeper insights and recommend reading it for a fuller understanding of the phenomenon. TL;DR Claim: Narrow finetunes leave clearly readable...
This post presents some motivation on why we work on model diffing, some of our first results using sparse dictionary methods and our next steps. This work was done as part of the MATS 7 extension. We'd like to thanks Cameron Holmes and Bart Bussman for their useful feedback. Could...
Clément Dumas, Walter Laurito, Robert Klassert, Kaarel Hänni Epistemic Status: Initial Exploration The following is a status update of a project started as part of the SPAR program. We explored some initial directions and there are still a lot of low-hanging fruits to pick up. We might continue to work...
