OpenAI Delays GPT-4.5 Rollout Due to GPU Shortage
OpenAI CEO Sam Altman announced that the rollout of the company's newest model, GPT-4.5, has been delayed due to a shortage of GPUs. Altman described the model as "giant" and "expensive," requiring "tens of thousands" more GPUs before wider access can be granted. GPT-4.5 will initially be available to ChatGPT Pro subscribers starting Thursday, followed by ChatGPT Plus users next week. The model's immense size contributes to its high cost: $75 per million input tokens and $150 per million output tokens, significantly more expensive than GPT-4. Altman attributed the GPU shortage to OpenAI's rapid growth, promising to add tens of thousands of GPUs next week to expand access. OpenAI plans to address future computing capacity limitations by developing its own AI chips and building a large network of data centers.
