Oumi vs. Chat Stream

Oumi is a completely open-source platform designed to improve the entire lifecycle of foundation models, covering aspects from data preparation and training through to evaluation and deployment. It supports the training and fine-tuning of models with parameter sizes spanning from 10 million to an astounding 405 billion, employing advanced techniques such as SFT, LoRA, QLoRA, and DPO. Oumi accommodates both text-based and multimodal models, and is compatible with a variety of architectures, including Llama, DeepSeek, Qwen, and Phi. The platform also offers tools for data synthesis and curation, enabling users to effectively create and manage their training datasets. Furthermore, Oumi integrates smoothly with prominent inference engines like vLLM and SGLang, optimizing the model serving process. It includes comprehensive evaluation tools that assess model performance against standard benchmarks, ensuring accuracy in measurement. Designed with flexibility in mind, Oumi can function across a range of environments, from personal laptops to robust cloud platforms such as AWS, Azure, GCP, and Lambda, making it a highly adaptable option for developers. This versatility not only broadens its usability across various settings but also enhances the platform's attractiveness for a wide array of use cases, appealing to a diverse group of users in the field.

Chat Stream provides users with access to two powerful language models created by DeepSeek, highlighting their exceptional performance capabilities. These models, known as DeepSeek V3 and R1, boast an impressive total of 671 billion parameters, with 37 billion activated for each token, and consistently deliver outstanding results on benchmarks like MMLU at 87.1% and BBH at 87.5%. With a generous context window length of 128K, they excel in various applications, including code generation, intricate mathematical calculations, and multilingual processing. They are built on an advanced Mixture-of-Experts (MoE) framework, utilize Multi-head Latent Attention (MLA), and incorporate auxiliary-loss-free load balancing along with a multi-token prediction approach to boost their efficiency. The deployment options are highly adaptable, featuring a web-based chat interface for instant use, straightforward integration into websites via iframes, and dedicated mobile applications available for iOS and Android platforms. Moreover, the models can operate on diverse hardware setups, including NVIDIA and AMD GPUs, as well as Huawei Ascend NPUs, facilitating both local inference and cloud deployment. Users enjoy multiple access methods, such as free chat without registration, options for website embedding, mobile app functionality, and an upgraded subscription that provides an ad-free experience while ensuring flexibility and ease of access for everyone. In addition, the versatility of these models allows users to explore a wide range of functionalities tailored to meet varied needs.
