OpenEuroLLM vs. GigaChat 3 Ultra

OpenEuroLLM embodies a collaborative initiative among leading AI companies and research institutions throughout Europe, focused on developing a series of open-source foundational models to enhance transparency in artificial intelligence across the continent. This project emphasizes accessibility by providing open data, comprehensive documentation, code for training and testing, and evaluation metrics, which encourages active involvement from the community. It is structured to align with European Union regulations, aiming to produce effective large language models that fulfill Europe’s specific requirements. A key feature of this endeavor is its dedication to linguistic and cultural diversity, ensuring that multilingual capacities encompass all official EU languages and potentially even more. In addition, the initiative seeks to expand access to foundational models that can be tailored for various applications, improve evaluation results in multiple languages, and increase the availability of training datasets and benchmarks for researchers and developers. By distributing tools, methodologies, and preliminary findings, transparency is maintained throughout the entire training process, fostering an environment of trust and collaboration within the AI community. Ultimately, the vision of OpenEuroLLM is to create more inclusive and versatile AI solutions that truly represent the rich tapestry of European languages and cultures, while also setting a precedent for future collaborative AI projects.

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.
