GPT-5.4 (xhigh) outperforms o1 on the intelligence index with a score of 57.2 compared to 30.8. For coding tasks, GPT-5.4 (xhigh) has the edge with a coding score of 57.3 vs 20.5.
o1 generates output significantly faster at 96 tok/s compared to GPT-5.4 (xhigh)'s 77 tok/s, making it 1.2x faster for streaming responses. Time to first token is 21.19s for o1 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 o1 costs $15/1M input ($60/1M output). That makes o1 6.0x 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, o1 would cost approximately $90.00/month vs $15.00/month for GPT-5.4 (xhigh) in input costs alone.
Choose GPT-5.4 (xhigh) when you need higher intelligence (57.2), stronger coding performance (57.3), lower cost.
GPT-5.4 (xhigh) scores higher on coding benchmarks (57.3 vs 20.5), making it the better choice for programming tasks.
GPT-5.4 (xhigh) is cheaper at $2.50/1M input tokens vs $15/1M for o1.
o1 is faster, producing output at 96 tok/s compared to GPT-5.4 (xhigh)'s 77 tok/s.
