GPT-5.1 vs Sora 2

1. Configurable Reasoning for Agentic Tasks

• Built to excel in autonomous or semi-autonomous coding workflows, with adjustable reasoning effort for planning, refactoring and debugging.

2. Fast Multi-Modal Input with Large Output

• Accepts both text and image inputs while producing text outputs.
• Offers up to 128 k output tokens, allowing long responses and code generation across multiple files.

3. Large Context & Knowledge Cut-Off

• 400 k token context window supports processing large codebases or documents.
• Knowledge cut-off of Sep 30 2024 ensures familiarity with recent tools and frameworks.

4. Reasoning Token Support

• Provides explicit support for reasoning tokens, enabling developers to fine-tune the balance between reasoning depth and speed.

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.

2. Synced Audio Generation

• Generates audio that aligns with the timing, actions, and mood of the video.
• Useful for creating complete media outputs without requiring external sound design.

3. Multi-Modal Input, Multi-Media Output

• Accepts text and image inputs, enabling:
  • Storyboard-to-video workflows
  • Image-to-video transformations
  • Concept illustrations expanded into full scenes
