RedPajama vs. GigaChat 3 Ultra

Foundation models, such as GPT-4, have propelled the field of artificial intelligence forward at an unprecedented pace; however, the most sophisticated models continue to be either restricted or only partially available to the public. To counteract this issue, the RedPajama initiative is focused on creating a suite of high-quality, completely open-source models. We are excited to share that we have successfully finished the first stage of this project: the recreation of the LLaMA training dataset, which encompasses over 1.2 trillion tokens. At present, a significant portion of leading foundation models is confined within commercial APIs, which limits opportunities for research and customization, especially when dealing with sensitive data. The pursuit of fully open-source models may offer a viable remedy to these constraints, on the condition that the open-source community can enhance the quality of these models to compete with their closed counterparts. Recent developments have indicated that there is encouraging progress in this domain, hinting that the AI sector may be on the brink of a revolutionary shift similar to what was seen with the introduction of Linux. The success of Stable Diffusion highlights that open-source alternatives can not only compete with high-end commercial products like DALL-E but also foster extraordinary creativity through the collaborative input of various communities. By nurturing a thriving open-source ecosystem, we can pave the way for new avenues of innovation and ensure that access to state-of-the-art AI technology is more widely available, ultimately democratizing the capabilities of artificial intelligence for all users.

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.
