Description

Chat Stream offers users the opportunity to tap into two robust language models developed by DeepSeek, showcasing their impressive capabilities. The models, DeepSeek V3 and R1, contain a staggering 671 billion parameters, with 37 billion activated per token, and consistently achieve remarkable benchmark performances, such as MMLU at 87.1% and BBH at 87.5%. With an extensive context window length of 128K, these models excel in tasks like code generation, complex mathematical computations, and processing multiple languages. Technically, they leverage an advanced Mixture-of-Experts (MoE) architecture, utilize Multi-head Latent Attention (MLA), feature auxiliary-loss-free load balancing, and implement a multi-token prediction objective to enhance performance. Deployment is versatile, providing a web-based chat interface for immediate access, easy integration into websites through iframes, and dedicated mobile applications for both iOS and Android devices. Furthermore, the models are compatible with various hardware, including NVIDIA, AMD GPUs, and Huawei Ascend NPUs, allowing for both local inference and cloud-based deployment. Users can benefit from different access methods, including free chat without the need for registration, website embedding options, mobile app usage, and a premium subscription that offers an ad-free experience, ensuring flexibility and accessibility for all.
