post-training steers models toward a particular region of persona space but only loosely tethers them to it

• How does different post-training data shift a model's position along persona dimensions?question0.864
  Future work direction: using persona space to study effects of training data on model character
• Post-training is key to eliciting strong introspective awareness; base pretrained models do not show above-chance detectionclaim0.795
  Finding that base models have high false positives and no net positive performance.
• Post-training is key to eliciting introspective awarenessfinding0.778
  Base pretrained models show high false positive rates and achieve no net task performance on concept injection detection; post-training essential for introspection.
• The Assistant Axis in instruct models mainly inherits from pre-existing helpful and harmless human personas in base models, later acquiring additional associations (such as being an AI) during post-trainingclaim0.777
  Key mechanistic claim about the developmental origin of the Assistant persona
• Training a model organism with known ground-truth deployment/evaluation behaviors allows validation that steering elicits deployment behavior rather than merely suppressing verbalizationsclaim0.776
  Methodological claim distinguishing this paper from prior work on verbalization suppression.
• Can off-the-rails model behavior be attributed to their persona drifting from the Assistant?question0.770
  Motivates the multi-turn conversation drift experiments in §4
• Post-training influences introspective capability expressionclaim0.769
  Different post-training strategies substantially influence introspection task performance; 'helpful-only' variants show higher false positives but some achieve strong net performance.
• Post-training strategies can strongly influence performance on introspective tasksclaim0.767
  Assertion about the role of post-training in eliciting introspection.
