The City of Rio de Janeiro's IT agency, IplanRIO, claimed to have developed an original 397-billion-parameter AI model named Rio-3.5-Open-397B. This model reportedly outperformed Alibaba's Qwen 3.7 Plus on several coding and reasoning benchmarks, generating significant public attention. However, an investigation by Nex-AGI revealed that Rio-3.5-Open-397B was not an original creation but rather a direct merge of Nex-AGI's Nex-N2-Pro model and Alibaba's Qwen3.5-397B-A17B base, with the model even identifying itself as Nex-AGI's creation when prompted.
