OpenAI’s latest model, GPT-5.6, reportedly demonstrates significant advancements in inference design, leading to enhanced performance in tasks requiring multi-step reasoning and tool use. The model utilizes more tokens at a lower cost, enabling higher throughput during inference, which has been beneficial for teams employing the system; one user noted a fivefold increase in token usage since adopting the new model. This improvement has been bolstered by specialized AI hardware, like Cerebras’ technology, which is pivotal in facilitating more efficient test-time computation.
