YuLan Mini Severe amounts of pre-training huge data have to be done to develop world-level large language models (LLMs) using transformer architectures that predict sequential tokens. Such preparation is costlier and resource-hungry and the computational infrastructural requirements are not easy to come by with specific well-constructed data pipelines. Balancing performance with resource consumption has attracted more attention among researchers who have begun seeking those competitive research options without going all the way to industry-scale resources as it becomes evident there is an ever-increasing demand for having these big efficient mainstream LLMs.
Designing large language models is full of processes that have misfortunes ranging from computation to data efficiency. Build pre-trained models for billions of parameters that need cutting-edge techniques and involve huge infrastructure. Quality data and good training methods are a prerequisite, as models are prone to instability in gradients and degraded performance. Open-source models have not been able to cope with proprietary models because they lack access to great computational hardware and quality datasets. This brings us to the challenge of building efficient high-performing models that small research groups can leverage in pushing the frontier in AI technology. Such an interaction calls for new approaches to managing data, stabilizing training, and designing architectures.
Existing research in LLM training emphasizes structured data pipelines, using techniques like data cleaning, dynamic scheduling, and curriculum learning to improve learning outcomes. However, stability remains a persistent issue. Large-scale training is susceptible to gradient explosions, loss spikes, and other technical difficulties, requiring careful optimization. Training long-context models introduce additional complexity as attention mechanisms’ computational demands grow quadratically with sequence length. Existing approaches like advanced optimizers, initialization strategies, and synthetic data generation help alleviate these issues but often fall short when scaled to full-sized models. The need for scalable, stable, and efficient methods in LLM training is more urgent than ever.
The YuLan-Mini was built by scholars from the Gaoling School of Artificial Intelligence, Renmin University of China. The language model currently boasts 2.42 billion parameters; combining that with data-efficient techniques would result in a gain in computational efficiency and performance. Leveraging publicly available data, YuLan-Mini is evidence of being outdone by employing data-efficient training techniques; indeed, performance is impressive vis-a-vis those of larger industry models.
YuLan-Mini’s architecture has great promise with regard to boosting the efficiency of training. The model’s decoder-only transformer architecture reduces the number of parameters without sacrificing training stability through embedding tying. One of the outstanding innovations of the YuLan-Mini model is its use of Rotary Positional Embedding (ROPE), extending its context size to 28,672 tokens, surpassing all models currently in use as it takes into account very long contexts. Major innovations include SwiGLU activation functions for richer data representation and an annealing strategy that carefully optimizes the allowances and promotes stability with respect to training while learning maximally. Synthetic data were also vital in filling part of the training from the open web pages, code repositories, and mathematical datasets. In total, this is worked on 1.08 trillion tokens. These features enable YuLan Mini to promise strong performance under a very constraining computing budget.
The YuLan-Mini scored 64.00 in zero-shot scenarios on HumanEval, 37.80 on MATH-500 in a four-shot setup, and finally, 49.10 on MMLU in five-shot tasks. All these results point toward the edge it has in comparison with the other models since this performance is comparable to much larger and more resource-hogging counterparts. The innovative context length extension to 28K tokens allowed YuLan Mini to excel in long-text scenarios while maintaining the same high accuracy in short-text tasks. This is what makes it different from many existing models, which usually sacrifice one for the other.
