nekomata-14b is an AI model developed by rinna (Japan), first published in December 2023. It works in the language domain, on tasks such as language generation.
Training it took an estimated 2.6×10²³ FLOP of compute (estimation method: operation counting). The model has 14,200,000,000 parameters. It was trained on roughly 66B datapoints. Training ran on 256 Amazon Trainium1 for about 168 hours.
Access: Open weights (restricted use). Its weights are openly available. It is built on top of Qwen-14B. The reference paper has 35 citations. Epoch AI rates the confidence of this record as confident.
