STORY: OpenAI has launched a new series of bots built to answer really tough questions. The AI models are designed to spend more time processing problems before spitting out an answer. First reported by Reuters, the new products are capable of reasoning through complex tasks. OpenAI says that makes them better able to solve challenging problems in science, coding and math. Known within the firm as ‘Strawberry’, they’ve officially been branded as o1 and o1-mini. The o1 version will be available in ChatGPT from Thursday. In a blog post, the firm said the new model scored 83% on the qualifying exam for the International Mathematics Olympiad. That compares with just 13% for a previous model. The new bot also exceeded human PhD-level accuracy on some scientific tests. An OpenAI researcher said the system was built on so-called “chain of thought” reasoning, which breaks complex problems down into small steps. The models have refined their abilities through training, and learning from their mistakes.
