Training For Engagement Can Degrade Alignment: Stanford Researchers coin “Moloch’s Bargain,” show fine-tuning can affect social values

Individuals and organizations increasingly use large language models to produce media that helps them compete for attention. Does fine-tuning LLMs to encourage engagement, purchases, or votes affect their alignment with social values? Researchers found that it does.

ChatGPT Shows Ads: OpenAI tests advertisements for U.S. chatbot users in free and lower-cost tiers

AI has a new revenue stream, and it looks a lot like old web banner ads.

Retrieval Faces Hard Limits: Google and Johns Hopkins researchers show embedding models can’t search unlimited documents

Can your retriever find all the relevant documents for any query your users might enter? Maybe not, research shows.

More Affordable Reasoning: Canadian researchers find capping context helps models better retrieve data

One way to improve a reasoning model’s performance is to let it produce a longer chain of thought. However, attending to ever-longer contexts can become expensive, and making that attention more efficient requires changes to a model’s architecture.

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.

Agents Write Code Faster, Cheaper: Software developers used more versatile AI-powered tools to write code

Coding apps moved beyond autofill-style code completion to agentic systems that manage a wide range of software development tasks.

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.

OpenAI’s Answer to Gemini 3: GPT-5.2 arrives, touting variable reasoning and coding performance

OpenAI launched GPT-5.2 only weeks after its CEO Sam Altman reportedly issued a “code red” alarm in response to Google's Gemini 3.

Claude Does More With Fewer Tokens: Claude Opus 4.5 retakes the coding crown at one-third the price of its predecessor

Claude Opus 4.5, the latest version of Anthropic’s flagship model, extends the earlier version’s strengths in coding, computer use, and agentic workflows while generating fewer tokens.

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.
