Build with GPT-5.4 freeGPT-5.4 vs Sora 2 for Research
Which AI model is better for research? We compare GPT-5.4 and Sora 2 on the criteria that matter most - with a clear verdict.
Why your research LLM choice matters
Research applications push LLMs to their limits - requiring synthesis across multiple long documents, careful reasoning about conflicting evidence, and structured output that meets academic standards. Context window size and factual accuracy are the two most critical factors: a model that summarises confidently but incorrectly is actively harmful in a research context.

Verdict: Best LLM for Research
For research tasks, GPT-5.4 edges ahead based on its performance profile and design priorities. It scores higher on depth and accuracy of scientific reasoning - the criterion that matters most for research workflows.
That said, Sora 2 remains a strong option. If structured output for reports and papers is a higher priority than raw performance, or if your team is already using OpenAI's tooling, Sora 2 can deliver strong results for research workloads.
