GigaChat 3 Ultra vs. GigaChat

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.

GigaChat excels in responding to user inquiries, engaging in interactive conversations, generating programming code, and crafting written content and images based on user-provided descriptions, all within a unified framework. Unlike other neural networks, GigaChat is intentionally built to support multimodal interactions and showcases exceptional skill in the Russian language. At its core, GigaChat is based on the NeONKA (NEural Omnimodal Network with Knowledge-Awareness) model, which integrates a wide range of neural network systems and utilizes methods like supervised fine-tuning and reinforcement learning that is augmented by human feedback. Consequently, Sber's pioneering neural network can effectively address a multitude of cognitive tasks, including engaging in stimulating dialogues, creating informative written content, and providing accurate answers to questions. Additionally, the incorporation of the Kandinsky 2.1 model within this framework significantly boosts its abilities, allowing it to generate detailed images in response to user prompts, which broadens the possible uses of the service. This diverse functionality not only enhances GigaChat’s versatility but also positions it as a leading tool in the field of artificial intelligence, making it a valuable asset for various applications.
