Nex-AGI accuses Rio of copying weights in Rio 3.5 Open model
Is this a scandal?
No longer — the story has resolved. Noise 7/100, cooling down, across 0 sources.
The open-source community will likely demand that Rio release their training logs or dataset details to prove the model's originality. If Rio fails to cooperate, the model is highly likely to be flagged or delisted from prominent platforms like Hugging Face.
Noise 7/100 — louder than 97% of tracked AI controversies.
Why it matters
This controversy highlights the growing challenge of verifying "original" training claims in the open-source AI ecosystem. It underscores the need for robust verification standards to prevent plagiarism and preserve trust in independent developers.
Key points
- Nex-AGI filed a GitHub issue alleging that the Rio 3.5 Open 397B model is a 60/40 weight blend of Nex-N2 Pro and Qwen rather than an original creation.
- Technical evidence presented by Nex-AGI indicates that the model weights align precisely across all 60 layers.
- The model allegedly defaults to identifying as "Nex" when its top-level system prompt is removed.
- The controversy has sparked wider industry discussions about transparency, verification, and the ethics of model merging.
The story
AI developer Nex-AGI has formally accused the creators of the Rio 3.5 Open 397B model of passing off a model blend as an original, independently trained project. According to a GitHub issue filed by Nex-AGI, the newly released 397-billion-parameter model is a 60/40 blend of Nex-N2 Pro and Alibaba's Qwen model. Nex-AGI alleges that the model's weights align precisely across all 60 layers with their proprietary weights, and notes that the model still identifies itself as "Nex" when its default system prompt is removed. Representatives for Rio have not yet officially resolved the allegations, which have sparked intense debate within the machine learning community regarding model authorship, licensing, and transparency.
