This model is deprecated. We only continue performance benchmarking for the default 10k input token workload. Results for other workloads are historical and no longer updated.

OpenAI has launched a newer model, GPT-5.6 Terra (xhigh). We suggest considering it instead.

For more information, see comparison of GPT-5.6 Terra (xhigh) to other models and API provider benchmarks for GPT-5.6 Terra (xhigh).
