Teaching Models to Tell the Truth: OpenAI fine-tuned a version of GPT-5 to confess when it was breaking the rules

Large language models occasionally conceal their failures to comply with constraints they’ve been trained or prompted to observe. Researchers trained an LLM to admit when it disobeyed.

Chatbots That Build Community by Sharon Zhou: Sharon Zhou of AMD on expanding chat to serve groups and connect us with other people

Next year, I’m excited to see AI break out of 1:1 relationships with each of us. In 2026, AI has the potential to bring people together and unite us with human connection, rather than polarize and isolate us. It’s about time for ChatGPT to enter your group chats.

Thinking Models Solve Bigger Problems: Reasoning models, beginning with OpenAI’s o1 and DeepSeek’s R1, transformed the industry

Think step by step. Explain your reasoning. Work backwards from the answer. As 2025 began, models executed these reasoning strategies only when prompted. Now most new large language models do it as a matter of course, improving performance across a wide range of tasks.

Adapting LLMs to Any Sort of Data: SEMI (Sample-Efficient Modality Integration) tackles new domains with few-shot examples

Enabling a pretrained large language model to process a data type other than text (say, images), possibly in a specialized domain (say, radiology), typically requires thousands to millions of examples that pair the other data (perhaps x-rays) with text.

Toward Steering LLM Personality: Persona Vectors allow model builders to identify and edit out sycophancy, hallucinations, and more

Large language models can develop character traits like cheerfulness or sycophancy during fine-tuning. Researchers developed a method to identify, monitor, and control such traits.

More-Efficient Agentic Search: Researchers fine-tune models to search their own parameters to boost recall

Large language models may have learned knowledge that’s relevant to a given prompt, but they don’t always recall it consistently. Fine-tuning a model to search its parameters as though it were searching the web can help it find knowledge in its own weights.

Masking Private Data in Training Sets: Google researchers released VaultGemma, an open-weights model redacting personal information

Large language models often memorize details in their training data, including private information that may appear only once, like a person’s name, address, or phone number. Researchers built the first open-weights language model that’s guaranteed not to remember such facts.
