Too close to call
It is close. Our weighted score puts them within a point (Nemotron 3 Super 120B A12B 54/100, Mercury 2 53/100, DeepSeek OCR 2 32/100), so choose by what matters most for your work: Nemotron 3 Super 120B A12B on price and Nemotron 3 Super 120B A12B for long inputs. 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 should you choose?
Which is better: Nemotron 3 Super 120B A12B, DeepSeek OCR 2 or Mercury 2?
It is close. Our weighted score puts them within a point (Nemotron 3 Super 120B A12B 54/100, Mercury 2 53/100, DeepSeek OCR 2 32/100), so choose by what matters most for your work: Nemotron 3 Super 120B A12B on price and Nemotron 3 Super 120B A12B for long inputs. 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, Nemotron 3 Super 120B A12B, DeepSeek OCR 2 or Mercury 2?
Nemotron 3 Super 120B A12B is cheaper at $0.20 input / $0.80 output per million tokens (official Nvidia API price). Mercury 2 costs $0.25 input / $0.75 output per million tokens (official Inception 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 $0.35 per million tokens for Nemotron 3 Super 120B A12B versus $0.375 for Mercury 2 (1.1× as much) and $1.03 for DeepSeek OCR 2 (3× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Nemotron 3 Super 120B A12B has not been scored yet, DeepSeek OCR 2 has not been scored yet and Mercury 2 has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Nemotron 3 Super 120B A12B, DeepSeek OCR 2 and Mercury 2 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?
Nemotron 3 Super 120B A12B has the largest context window at 262,144 tokens, against 128,000 for Mercury 2 and 8,192 for DeepSeek OCR 2. Maximum output per response: Nemotron 3 Super 120B A12B up to 262,144, DeepSeek OCR 2 up to 8,192, Mercury 2 up to 50,000 tokens.
Which can read images, PDFs, audio or video?
Nemotron 3 Super 120B A12B accepts text; DeepSeek OCR 2 accepts text and images; Mercury 2 accepts text. DeepSeek OCR 2 handles the widest range of inputs.
Are any of these open source?
Nemotron 3 Super 120B A12B and DeepSeek OCR 2 publishes its weights and can be self-hosted; Mercury 2 is proprietary.
Which is newer?
Nemotron 3 Super 120B A12B is the newest, released Mar 11, 2026. Mercury 2 came out Feb 24, 2026; DeepSeek OCR 2 came out Jan 27, 2026. Knowledge cutoff: Mercury 2 Jan 1, 2025.
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.
