OpenAI Unveils GPT-4.5: Friendliest Model Yet at 1300% the Price – BitRss

OpenAI released GPT-4.5 on Thursday, just one day after Anthropic launched Claude 3.7 Sonnet and merely a week following xAI’s Grok-3 debut and DeepSeek’s announcement of a new model coming soon.

And expensive is the operative word here. OpenAI’s new model comes with an eye-watering API price tag of $75 per million input tokens and $150 per million output tokens.

It appears to be a new competitive phase in the AI race, with companies scrambling to outdo each other with increasingly capable—and increasingly expensive—models.
