While the world’s leading artificial intelligence companies race to build ever-larger models, betting billions that scale alone will unlock artificial general intelligence, a researcher at one of the industry’s most secretive and valuable startups delivered a pointed challenge to that orthodoxy this week: The path forward isn’t about training bigger — it’s about learning better.”I believe that the first superintelligence will be a superhuman learner,” Rafael Rafailov, a reinforcement learning researcher at Thinking Machines Lab, told an audience at TED AI San Francisco on Tuesday. “It will be able to very efficiently figure out and adapt, propose its own theories, propose experiments, use the environment to verify that, get information, and iterate that process.”This breaks sharply with the approach pursued by OpenAI, Anthropic, Google DeepMind, and other leading laboratories, which have bet billions on scaling up model size, data, and compute to achieve increasingly sophisticated reasoning capabilities. Rafailov argues these companies have the strategy backwards: what’s missing from today’s most advanced AI systems isn’t more scale — it’s the ability to actually learn from experience.”Learning is something an intelligent being does,” Rafailov said, citing a quote he described as recently compelling. “Training is something that’s being done to it.”The distinction cuts to the core of how AI systems improve — and whether the industry’s current trajectory can deliver on its most ambitious promises. Rafailov’s comments offer a rare window into the thinking at Thinking Machines Lab, the startup co-founded in February by former OpenAI chief technology officer Mira Murati that raised a record-breaking $2 billion in seed funding at a $12 billion valuation.Why today’s AI coding assistants forget everything they learned yesterdayTo illustrate the problem with current AI systems, Rafailov offered a scenario familiar to anyone who has worked with today’ …
