OpenAI pushes GPT-5.6 Sol to 750 tokens/sec

OpenAI has put GPT-5.6 Sol into a limited Ultrafast preview that runs up to 14× faster than standard processing and produces up to 750 output tokens per second. TechCrunch’s report on the launch says Cerebras powers the service tier and that access will expand as capacity grows. That makes latency—not just benchmark score—the new filing-away variable for teams deciding whether a frontier model can sit inside live support, incident response, or checkout flows; the archive’s case for rationing AI tokens remains the cost counterweight.
