How Sora 2 and Grok 4 differ
What the numbers mean in practice when choosing between Sora 2 and Grok 4.
-
Sora 2's 400K tokens context window is roughly 1.6x larger than Grok 4's 256K 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 Grok 4 is a text 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

FAQs
Pricing models differ: see the full Sora 2 and Grok 4 pages in the Appaca AI models directory for current pricing details.
Sora 2 has the larger context window at 400K tokens, compared to 256K tokens for Grok 4. A larger window means the model can consider more text at once - useful for long contracts, codebases, or months of records.
It depends on the job. Compare the pricing, context window, and strengths above against your workload - and remember the choice isn't permanent. In Appaca you can build a tool on Sora 2, test the same tool on Grok 4, and switch at any time without rebuilding anything.
