LearnLM is an experimental, task-specific model designed to align with learning science principles for teaching and learning applications. It is trained to respond to system instructions like "You are an expert tutor," and is capable of inspiring active learning by encouraging practice and providing timely feedback. The model effectively manages cognitive load by presenting relevant, well-structured information across multiple modalities, while dynamically adapting to the learner’s goals and needs, grounding responses in appropriate materials. LearnLM also stimulates curiosity, motivating learners throughout their educational journey, and supports metacognition by helping learners plan, monitor, and reflect on their progress. This innovative model is available for experimentation in AI Studio.

GPT-5.1 is the latest update in the GPT-5 series, designed to make ChatGPT dramatically smarter and more conversational. The release introduces two distinct model variants: GPT-5.1 Instant, which is described as the most-used model and is now warmer, better at following instructions, and more intelligent; and GPT-5.1 Thinking, which is the advanced reasoning engine that’s been tuned to be easier to understand, faster on straightforward tasks, and more persistent on complex ones. Users' queries are now routed automatically to the variant best-suited to the task. The update emphasizes not just improved raw intelligence but also enhanced communication style; the models are tuned to be more natural, enjoyable to talk to, and better aligned with user intents. The system card addendum notes that GPT-5.1 Instant uses “adaptive reasoning” that lets it decide when to think more deeply before responding, while GPT-5.1 Thinking adapts its thinking time accurately to the question at hand.
