Parameter Normalization

How we handle parameters across different providers

Not every provider speaks the same language. When you send a parameter, we handle it in one of four ways depending on what the model supports:

Behavior What happens Example
passthrough Sent as-is to the provider style, quality
renamed Same value, mapped to the field name the provider expects prompt
converted Transformed to the provider's native format size
emulated Works even if the provider has no concept of it n, response_format

Parameters we don't recognize pass straight through to the upstream API, so provider-specific options still work.

Overview

Sora 2 is a high-fidelity video generation model developed by OpenAI that transforms text prompts or static images into cinematic video sequences. It represents an evolution in the Sora family, capable of producing content at 720p resolution with extended durations reaching up to 20 seconds. This model is distinguished by its ability to maintain temporal consistency and complex motion dynamics over longer spans than many first-generation video models.

Strengths

  • Temporal Consistency: Maintains the identity of characters, objects, and environmental details across the entire 20-second duration, minimizing the “morphing” or warping effects common in shorter-clip models.
  • Physical Simulation: Demonstrates a sophisticated understanding of physical interactions, such as fluid dynamics, lighting reflections, and gravity, leading to more realistic movement.
  • Multimodal Input Flexibility: Supports both text-to-video for purely generative tasks and image-to-video for animating existing assets or extending still photography into motion.
  • Enhanced Resolution: Outputs native 720p video, providing sufficient clarity for social media content, prototyping, and digital backgrounds without immediate need for upscaling.

Limitations

  • Causal Reasoning: While physically grounded, the model may still struggle with complex “cause and effect” sequences, such as a character taking a bite out of a cookie and the cookie not showing a bite mark.
  • Spatial Confusion: In high-action scenes involving multiple moving parts (e.g., a crowded street), the model can occasionally mix up left/right orientations or produce impossible limb movements.
  • Resolution Ceiling: At 720p, it lacks the native 4K or 1080p detail required for professional film production pipelines without significant post-processing.

Technical Background

Sora 2 utilizes a diffusion transformer (DiT) architecture, which combines the scaling properties of transformers with the generative capabilities of diffusion models. It operates on spacetime patches, treating video data as a three-dimensional collection of patches that allow the model to train on diverse aspect ratios and resolutions. This architecture enables the model to look ahead and behind in a sequence to ensure global coherence rather than generating frames in a strictly linear, autoregressive fashion.

Best For

Sora 2 is best suited for rapid prototyping in creative agencies, generating b-roll for digital marketing, and creating environmental backgrounds for web design. It excels at animating conceptual art where maintaining character consistency is a priority. This model is available for testing and integration through Lumenfall’s unified API and playground, allowing developers to compare its outputs directly against other video generation frameworks.
