GPT-5 Image or o1: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GPT-5 Image for output tokens 6.0x cheaper ($10.00 vs $60.00 per million) and a larger context window (400K against 200K tokens).
No benchmark has tested both yet. GPT-5 Image has results on Design Arena: images, Design Arena: graphic design and Design Arena: logos; o1 on Aider polyglot, AA Coding Index and LiveCodeBench (Vals AI). Compare them on price and context instead.

Benchmark by benchmark
Every board either model has a result on, a category to a fold; bars are each result on a 0 to 100 scale. Only one model is measured on each, so no row names a leader.

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
Chat turn
1K input + 500 output tokens
GPT-5 Image costs less
Repository review
50K input + 3K output tokens
GPT-5 Image costs less
Agent loop
200K input + 10K output tokens
GPT-5 Image costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.

Questions
Is GPT-5 Image better than o1 for coding?
Neither model has a coding score yet, so the two cannot be ranked on coding. Pick GPT-5 Image for output tokens 6.0x cheaper ($10.00 vs $60.00 per million) and a larger context window (400K against 200K tokens).
Which is cheaper, GPT-5 Image or o1?
GPT-5 Image costs $10.00 per million input tokens and $10.00 per million output tokens; o1 costs $15.00 and $60.00. Cost per solved task is known for neither of them.
Which has the bigger context window, GPT-5 Image or o1?
GPT-5 Image, with 400K tokens against 200K.
Has any benchmark tested both GPT-5 Image and o1?
No benchmark has tested both yet. GPT-5 Image has results on Design Arena: images, Design Arena: graphic design and Design Arena: logos; o1 on Aider polyglot, AA Coding Index and LiveCodeBench (Vals AI). Compare them on price and context instead. Data as of October 21, 2026.
