GPT-5.2 Instant vs DeepSeek LLM 2.0

Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.

GPT-5.2 Instant is clearly ahead on the aggregate, 85 to 62. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-5.2 Instant's sharpest advantage is in coding, where it averages 75.5 against 42.9. The single biggest benchmark swing on the page is LiveCodeBench, 74 to 39.

GPT-5.2 Instant is the reasoning model in the pair, while DeepSeek LLM 2.0 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use.

Quick Verdict

Pick GPT-5.2 Instant if you want the stronger benchmark profile. DeepSeek LLM 2.0 only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
