Which should you choose?
Which is better: GPT-4o or Nova Pro?
Nova Pro is the better all-round choice, scoring 48/100 against GPT-4o (43). It leads on price and context window. GPT-4o wins on capability. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.
Which is cheaper, GPT-4o or Nova Pro?
Nova Pro is cheaper at $0.80 input / $3.20 output per million tokens (official Amazon Bedrock API price). GPT-4o costs $2.50 input / $10.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $1.40 per million tokens for Nova Pro versus $4.38 for GPT-4o (3.1× as much).
Which scores higher on benchmarks?
GPT-4o scores higher on the Capabilities Index (ECI): GPT-4o 129.0 (#129 of 148) and Nova Pro 123.8 (#137 of 148). The confidence ranges of the top two overlap (124.2–131.5 vs 108.8–126.6), so treat the gap as small.
Which is better for coding?
There are no published SWE-bench Verified results for GPT-4o and Nova Pro yet, so there is no like-for-like coding score. On overall capability, GPT-4o leads, which tends to carry over to coding, but test on your own codebase. Both support tool calling for agent workflows.
Which has the bigger context window?
Nova Pro has the largest context window at 300,000 tokens, against 128,000 for GPT-4o. Maximum output per response: GPT-4o up to 16,384, Nova Pro up to 10,000 tokens.
Which can read images, PDFs, audio or video?
GPT-4o accepts text, images and PDFs; Nova Pro accepts text, images, PDFs and video. Nova Pro handles the widest range of inputs.
Are any of these open source?
No. GPT-4o and Nova Pro are proprietary and only available through APIs and apps.
Which is newer?
Nova Pro is the newest, released Dec 3, 2024. GPT-4o came out May 13, 2024. Knowledge cutoff: GPT-4o Sep 2023, Nova Pro Oct 2024.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
