Claims
- GPT-5.6 Sol will achieve 750 tokens per second when served on Cerebras hardware, arriving in July.
- This represents up to 15x the throughput of GPT-5.5 priority tier service, which guarantees 99% of requests at over 50 tokens per second.
- The speed gain comes from Cerebras's wafer-scale chip architecture, which reduces memory and networking latency compared to conventional multi-GPU inference setups.
Key quotes
750 token/sec coming to 5.6 sol in july!
Sol on Cerebras is claiming up to 15x that rate.
Cerebras, whose wafer-scale chip is designed to move model data with far less memory and networking delay than a normal multi-GPU setup.
