What is ChatDLM
ChatDLM is the world's fastest diffusion language model launched by Qafind Labs, with its core positioning being to break through the bottlenecks of traditional Transformer architectures in long-context processing and inference efficiency. The model integrates "Block Diffusion" and "Mixture-of-Experts (MoE)" technologies, has 7B parameters, achieves an inference speed of up to 2800 tokens/s, and supports an ultra-large context window of 131,072 tokens. In performance tests, ChatDLM achieved an accuracy of 92.0% on the Humaneval (0-shot) test and 84.2% on the Fill-in-the-Middle test, demonstrating outstanding performance.
Main features of ChatDLM
- Efficient text generation: ChatDLM has an extremely high inference speed, generating more than 2800 tokens per second, enabling real-time responses and making conversations more fluent and natural. It supports ultra-long context processing of up to 131,072 tokens, easily handling complex scenarios such as long document generation and dialogue history tracking.
- Controllable generation and local repair: ChatDLM can precisely control text generation to meet specific needs and customize output content. It can seamlessly edit specific parts of generated content without regenerating the entire text, greatly improving flexibility.
- Resource efficient: ChatDLM's optimized architecture reduces computing requirements, lowering operating costs by 30%, and is suitable for a variety of professional scenarios.
- Dynamic optimization and domain adaptation: Through a dynamic early-stopping mechanism and iteration step prediction, ChatDLM reduces ineffective computation while maintaining high accuracy. In vertical domains such as law and healthcare, ChatDLM can increase domain knowledge recall to 95.6% through expert weight fine-tuning.
Technical principles of ChatDLM
- Block Diffusion technology: ChatDLM adopts Block Diffusion technology, dividing input text into multiple blocks according to semantic units. Each block independently performs spatial diffusion computation, and global information interaction is achieved through cross-block attention mechanisms. This reduces complexity from the traditional O(n²) to O(n log n), significantly improving computational efficiency.
- Mixture-of-Experts (MoE) mechanism: ChatDLM is configured with 32 to 64 expert modules, and only 2 experts are activated for computation each time. Tasks are dynamically assigned through a Gating Network, allowing the model to reduce computation by 70% while maintaining accuracy. The Mixture-of-Experts mechanism supports domain-adaptive optimization, and through expert weight fine-tuning, domain knowledge recall can be increased to 95.6%.
- Long-context processing solution: To support ultra-long contexts, ChatDLM adopts Rotary Position Embedding (RoPE) optimization technology and a hierarchical caching strategy. RoPE enhances the model's ability to perceive positions in long sequences, and the hierarchical caching strategy can achieve a cache hit rate of 98.2% with 130,000-token input. The dynamic early-stopping mechanism reduces ineffective computation by 40% through iteration step prediction (converging in an average of 12-25 steps).
- Inference optimization: Through technologies such as dynamic early stopping, BF16 mixed precision, and ZeRO sharding, ChatDLM achieves seamless scaling across multiple GPUs. This further improves the model's operating efficiency and scalability.
- Parallel decoding and local repair: ChatDLM combines block diffusion and parallel decoding technology to simultaneously optimize multiple parts of text, unlike the sequential generation method of traditional models. This improves generation speed and supports local correction of specific parts of text without regenerating the entire content.
