OpenAI has announced the release of GPT-4.5, its latest language model which they are calling their 'last non-chain-of-thought model.' According to OpenAI, GPT-4.5 offers substantial enhancements over its predecessors, particularly in advanced reasoning, problem-solving, and contextual understanding. Sam Altman, CEO of OpenAI, described it as the "first model that feels like talking to a thoughtful person," noting moments of astonishment at the quality of advice received from the AI.
However, the rollout is facing challenges due to GPU shortages. Altman stated they are "out of GPUs," leading to a staggered release, initially limited to ChatGPT Pro subscribers who pay $200 a month. While GPT-4.5 is available to developers across all paid API tiers, OpenAI plans to expand access to Plus and Team tiers next week, with tens of thousands of GPUs expected to arrive to alleviate the supply constraints. Despite not being a reasoning model, OpenAI estimates that GPT-4.5 is 30 times more expensive to run than GPT-4o.
