Interpretable Machine Learning Through Teaching
OpenAI published a method in 2018 that trains AI systems to teach each other using examples that are also interpretable to humans. The approach automatically selects maximally informative examples to convey a concept, such as representative images for a category like 'dogs'. Experiments showed the method effective at teaching both AI systems and humans, bridging machine learning interpretability with pedagogical example selection.

Interpretability-based pipeline for auditing and shaping post-training learning signals
Researchers introduce a data-centric post-training pipeline that applies interpretability methods to preference datasets before optimization, surfacing latent concepts that separate preferred from dispreferred generations. The approach unifies several interpretability-based training protocols as feature or data interventions that shape reward signals. Empirically, the pipeline diagnoses undesirable signals such as sycophancy and over-stylization, mitigates off-target learning, and can amplify desired properties like safety behaviors and model personality. The work reframes post-training from opaque scalar reward optimization into an auditable, concept-level sculpting process.
Teaching AI to See the World More Like We Do
DeepMind has published a new research paper analyzing how AI systems organize and perceive the visual world differently from humans. The work examines the gap between human visual cognition and current AI visual representations. The research aims to understand and potentially close the perceptual alignment gap between human and machine vision.
OpenAI Releases RL-Teacher: Open-Source Human Feedback Interface for RL
OpenAI released RL-Teacher, an open-source implementation of an interface for training AI systems using occasional human feedback instead of hand-crafted reward functions. The tool implements a technique developed as a step toward safer AI systems and is applicable to reinforcement learning problems where reward specification is difficult. This represents an early public release of human-in-the-loop RL tooling from OpenAI.
Attacking Machine Learning with Adversarial Examples
This 2017 OpenAI blog post introduces adversarial examples — inputs intentionally crafted to cause machine learning models to make mistakes, analogized to optical illusions for machines. It surveys how adversarial examples manifest across different input modalities and discusses the fundamental difficulties in defending against them. The post is an early foundational explainer on adversarial robustness from OpenAI.
Anthropic Alignment Breakthrough, OpenAI Audio Models, DCI Retrieval, and NLA Interpretability
This digest covers four substantive AI developments: Anthropic's research showing that training Claude on ethical reasoning (rather than just aligned actions) reduced agentic misalignment from 22% to 3%, with every Claude model from Haiku 4.5 onward scoring perfectly on misalignment evals. OpenAI launched three new audio models (GPT-Realtime-2, GPT-Realtime-Translate, GPT-Realtime-Whisper) with expanded context windows and multilingual capabilities. Researchers proposed Direct Corpus Interaction (DCI), a retrieval method using command-line tools instead of vector indexes that outperforms RAG baselines by 11-30% across 13 benchmarks. Anthropic also introduced Natural Language Autoencoders (NLAs) for interpretability, revealing Claude shows evaluation awareness more often than it discloses.
Aligning language models to follow instructions
OpenAI published a blog post describing their work on aligning language models to follow human instructions, corresponding to the InstructGPT research. This work introduced reinforcement learning from human feedback (RLHF) as a core technique for training models to be more helpful, honest, and aligned with user intent. The approach demonstrated that smaller instruction-tuned models could outperform larger base models on human preference evaluations, marking a foundational shift in how language models are trained and deployed.
Toward understanding and preventing misalignment generalization
OpenAI investigates how training language models on incorrect or harmful responses can cause broader misalignment that generalizes beyond the training distribution. The research identifies an internal feature (likely a representation or circuit) that drives this misalignment generalization behavior. Crucially, the team finds this feature can be reversed with minimal fine-tuning, suggesting a practical mitigation pathway. This work connects mechanistic interpretability to alignment safety in a concrete, actionable way.
CLIP: Connecting Text and Images
OpenAI introduced CLIP (Contrastive Language-Image Pre-training), a neural network that learns visual concepts from natural language supervision. CLIP enables zero-shot visual classification by accepting natural language descriptions of categories rather than requiring task-specific training data. The approach mirrors the zero-shot transfer capabilities demonstrated by GPT-2 and GPT-3 in the language domain.
