Beyond the KV cache: Training and serving i14’s Laplace 3B linear attention model on AWS Trainium2 with native PyTorch
AWS Machine Learning blog showcases i14's training and serving of Laplace 3B, a linear attention model on AWS Trainium2 that maintains a constant recurrent state of 29.5 MB per sequence.
Why this signal matters
The AWS Machine Learning blog detailed the training and deployment of i14’s Laplace 3B linear attention model on AWS Trainium2 hardware using native PyTorch. In contrast to conventional transformer architectures that face memory scaling challenges due to expanding KV caches during long context generation, Laplace 3B maintains a constant recurrent state size of 29.5 MB per sequence regardless of context length, stabilizing serving memory requirements.
Actionable summary
i14 demonstrated training and serving Laplace 3B, a linear attention model on AWS Trainium2 via native PyTorch, eliminating KV-cache growth by keeping recurrent state fixed at 29.5 MB per sequence.
