GPT-5.4 (xhigh) generates output significantly faster at 77 tok/s compared to GPT-5.4 Pro (xhigh)'s 0 tok/s, making it Infinityx faster for streaming responses. Time to first token is 0.00s for GPT-5.4 Pro (xhigh) vs 181.82s for GPT-5.4 (xhigh), which affects perceived responsiveness in interactive applications.
GPT-5.4 (xhigh) is more affordable at $2.50/1M input tokens ($15/1M output), while GPT-5.4 Pro (xhigh) costs $30/1M input ($180/1M output). That makes GPT-5.4 Pro (xhigh) 12.0x more expensive per token, which can add up significantly at scale. For a typical workload of 100 requests per day at 2,000 tokens each, GPT-5.4 Pro (xhigh) would cost approximately $180.00/month vs $15.00/month for GPT-5.4 (xhigh) in input costs alone.
Choose GPT-5.4 (xhigh) when you need faster output (77 tok/s), lower cost.
GPT-5.4 (xhigh) is cheaper at $2.50/1M input tokens vs $30/1M for GPT-5.4 Pro (xhigh).
GPT-5.4 (xhigh) is faster, producing output at 77 tok/s compared to GPT-5.4 Pro (xhigh)'s 0 tok/s.
