How Sora 2 and GPT-4o Audio differ
What the numbers mean in practice when choosing between Sora 2 and GPT-4o Audio.
-
Sora 2's 400K tokens context window is roughly 3.1x larger than GPT-4o Audio's 128K tokens, so it can work across bigger codebases, contracts, or archives in one pass.
-
These are different kinds of model: Sora 2 is a video model while GPT-4o Audio is an audio model, so they often complement each other in a workflow rather than compete.
Strengths side by side
Where each model shines, according to benchmarks and provider positioning.
Sora 2
1. Advanced Video Generation Capability
- Produces richly detailed, cinematic video clips from simple text or image prompts.
- Handles complex scenes, motion, lighting, environments, and multi-object interactions with high fidelity.
