OpenAI rebuilt its inference stack with Astra to create GPT-6.1 Sol
Tibo said OpenAI gave Astra to its strongest engineers, who rewrote the inference stack to produce GPT-6.1 Sol, nearly as intelligent as Astra at a fifth of the price.
Here's what's actually wild about what's happening inside openai right now. Tibo explained how gpt-6.1 sol was even possible they gave their smartest engineers astra, and those engineers started doing things previously considered almost impossible. They used astra to rethink the entire inference stack. that's how 6.1 sol is almost as intelligent as astra at a fifth of the price. "we push the frontier and then we make things more affordable and more broadly available." but it's not just models. ultra fast has changed how openai itself ships.
