OpenAI’s Sora AI video generator produced a surreal and technically flawed video of a gymnast performing impossible movements, including sprouting extra limbs and temporarily losing her head during what was meant to be an Olympic-style floor routine.

Technical breakdown of the issue: The video synthesis errors stem from Sora’s fundamental approach to generating content through statistical associations rather than true understanding of physics or human anatomy.

  • Sora creates videos by analyzing training data that pairs video footage with text descriptions
  • The system makes continuous next-frame predictions based on the previous frame
  • While Sora attempts to maintain coherency by looking ahead at multiple frames, it struggles with rapid movements and complex physics

Training data limitations: The model’s performance is directly tied to the quantity and quality of its training examples.

  • The system relies on AI-generated labels to describe training videos
  • Limited gymnastics footage in the training data leads to inconsistent predictions
  • Complex movements prove especially challenging due to insufficient examples of precise limb-level movements

Industry perspective: This phenomenon extends beyond just Sora to other AI video generators.

  • Runway’s Gen-3 and Hunyuan Video face similar challenges with complex movements
  • These issues emerge when prompts exceed the boundaries of the model’s training data
  • The problems highlight the imitative nature of transformer-based AI models

Technical terminology: Industry experts have begun referring to these AI-generated anomalies as “jabberwockies” – nonsensical outputs that fail to produce plausible results, distinct from mere hallucinations or confabulations.

  • The term derives from Lewis Carroll’s nonsense poetry
  • These errors represent complete failures in generating coherent output
  • Similar issues have appeared in various AI video applications, from commercials to celebrity deepfakes

Future developments: Improvement in AI video generation will require significant advances in several areas.

  • Massive amounts of well-labeled training data
  • Increased computational power for processing
  • Better understanding and implementation of physics rules
  • More sophisticated approaches to maintaining consistency across frames

Looking ahead: While current limitations in AI video generation are evident, the technology’s rapid evolution suggests significant improvements are likely, though true physics-based “world simulation” remains a distant goal. The progression may mirror the development of AI image generation, which advanced from abstract shapes to highly realistic imagery in a relatively short time.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment

The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
