04 — Questions

Which should you choose?

Which is better: DeepSeek OCR 2 or GPT-5 Nano?

GPT-5 Nano is the better all-round choice, scoring 75/100 against DeepSeek OCR 2 (32). It leads on price, inputs & features and context window. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which is cheaper, DeepSeek OCR 2 or GPT-5 Nano?

GPT-5 Nano is cheaper at $0.05 input / $0.40 output per million tokens (official OpenAI API price). DeepSeek OCR 2 costs $0.89 input / $1.47 output per million tokens (median across 1 API provider). At a typical mix of three input tokens to one output token, that is $0.138 per million tokens for GPT-5 Nano versus $1.03 for DeepSeek OCR 2 (7.5× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers both models yet. DeepSeek OCR 2 has not been scored yet and GPT-5 Nano has an ECI of 139.4.

Which is better for coding?

There are no published SWE-bench Verified results for DeepSeek OCR 2 and GPT-5 Nano yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that DeepSeek OCR 2 does not support tool calling, which most coding agents need.

Which has the bigger context window?

GPT-5 Nano has the largest context window at 400,000 tokens, against 8,192 for DeepSeek OCR 2. Maximum output per response: DeepSeek OCR 2 up to 8,192, GPT-5 Nano up to 128,000 tokens.

Which can read images, PDFs, audio or video?

DeepSeek OCR 2 accepts text and images; GPT-5 Nano accepts text and images. They handle the same number of input types.

Are any of these open source?

DeepSeek OCR 2 publishes its weights and can be self-hosted; GPT-5 Nano is proprietary.

Which is newer?

DeepSeek OCR 2 is the newest, released Jan 27, 2026. GPT-5 Nano came out Aug 7, 2025. Knowledge cutoff: GPT-5 Nano May 30, 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.
