Qwen 1.8B is a large language model developed by Alibaba Qwen (Qwenlm) with 1.8 billion parameters. It operates under the Tongyi Qianwen Research License Agreement (TQRLA), emphasizing improved human preference in chat models. The model is designed to enhance conversational interactions while adhering to specific research and usage guidelines.
Description of Qwen 1.8B
Qwen1.5 is the beta version of Qwen2, a transformer-based decoder-only language model pretrained on extensive data. It offers 8 model sizes including 0.5B, 1.8B, 4B, 7B, 14B, 32B, 72B dense models, and a 14B MoE model with 2.7B activated. Key features include improved chat models, multilingual support, and a stable 32K context length. The architecture employs Transformer with SwiGLU activation, attention QKV bias, and group query attention. Its tokenizer adapts to multiple natural languages and codes. However, the beta version lacks GQA (except for 32B) and the mixture of SWA and full attention.
Parameters & Context Length of Qwen 1.8B
Tags: 1.8b, 32k
Qwen 1.8B is a large language model with 1.8 billion parameters, placing it in the small model category, which ensures fast and resource-efficient performance for simple tasks. Its 32,000-token context length allows handling extended texts, though it requires more computational resources compared to shorter contexts. This combination makes it suitable for applications prioritizing efficiency while maintaining the ability to process lengthy inputs.
