OpenAI CEO Sam Altman outlined a three-step strategy at the company's developer conference in San Francisco on Tuesday: build the best AI models, make them easy for developers to use, and create a marketplace connecting business customers. The company announced GPT-6.1 Sol, an affordable alternative to its latest Astra model, alongside Ultrafast, a more expensive high-speed access option. OpenAI also added its Codex coding tool to the cloud and introduced APIs (software interfaces for building applications), including one for creating agents and another designed for rapid decision-making. With more than 1.2 billion people using ChatGPT each week, OpenAI is expanding its role as an intermediary by allowing businesses to apply existing commitments toward partner products and enabling users to sign in to other AI products with ChatGPT and use their token allotments. The strategy comes as Anthropic, Meta, Google, SpaceXAI and Chinese competitors challenge OpenAI on model capability and price.
