GigaChat 3 Ultra vs. Chat Stream

GigaChat 3 Ultra is a breakthrough open-source LLM, offering 702 billion parameters built on an advanced MoE architecture that keeps computation efficient while delivering frontier-level performance. Its design activates only 36 billion parameters per step, combining high intelligence with practical deployment speeds, even for research and enterprise workloads. The model is trained entirely from scratch on a 14-trillion-token dataset spanning ten+ languages, expansive natural corpora, technical literature, competitive programming problems, academic datasets, and more than 5.5 trillion synthetic tokens engineered to enhance reasoning depth. This approach enables the model to achieve exceptional Russian-language capabilities, strong multilingual performance, and competitive global benchmark scores across math (GSM8K, MATH-500), programming (HumanEval+), and domain-specific evaluations. GigaChat 3 Ultra is optimized for compatibility with modern open-source tooling, enabling fine-tuning, inference, and integration using standard frameworks without complex custom builds. Advanced engineering techniques—including MTP, MLA, expert balancing, and large-scale distributed training—ensure stable learning at enormous scale while preserving fast inference. Beyond raw intelligence, the model includes upgraded alignment, improved conversational behavior, and a refined chat template using TypeScript-based function definitions for cleaner, more efficient interactions. It also features a built-in code interpreter, enhanced search subsystem with query reformulation, long-term user memory capabilities, and improved Russian-language stylistic accuracy down to punctuation and orthography. With leading performance on Russian benchmarks and strong showings across international tests, GigaChat 3 Ultra stands among the top five largest and most advanced open-source LLMs in the world. It represents a major engineering milestone for the open community.

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.
