What is MPT-7B-StoryWriter?
MPT-7B-StoryWriter is a specialized language model designed specifically for reading and writing fictional stories with exceptionally long context lengths. Developed by MosaicML, this model represents a significant advancement in long-form content generation, capable of handling contexts up to 65k tokens and even extrapolating beyond to 84k tokens during inference.
Implementation Details
The model employs several cutting-edge architectural innovations, including FlashAttention for efficient computation, ALiBi (Attention with Linear Biases) for position encoding, and operates without traditional positional embeddings or bias terms. Built on a modified decoder-only transformer architecture, it features 32 layers, 32 attention heads, and a model dimension of 4096.
- Utilizes FlashAttention for optimal performance
- Implements ALiBi for position-aware attention
- Supports dynamic context length extension
- Trained on 8 A100-80GB GPUs using FSDP and LION optimizer
Core Capabilities
- Long-form story generation and continuation
- Extended context understanding (65k+ tokens)
- Efficient processing with FlashAttention support
- Commercial usage permitted under Apache 2.0 license
