Recently, NVIDIA has made new strides in the field of artificial intelligence with the introduction of their Minitron series of small language models, which include 4B and 8B versions. These models have not only increased training speed by a full 40 times but also make it easier for developers to use them for various applications, such as translation, sentiment analysis, and conversational AI.
You might wonder, why are small language models so important? Traditional large language models, while powerful, have very high training and deployment costs, often requiring a vast amount of computational resources and data. To make these advanced technologies more accessible to a wider audience, NVIDIA's research team came up with an ingenious solution: combining "pruning" and "knowledge distillation" techniques to efficiently reduce the model's size.
Specifically, researchers start with an existing large model and prune it. They evaluate the importance of each neuron, layer, or attention head in the model and remove those that are less significant. This way, the model becomes much smaller, and the resources and time required for training are greatly reduced. Next, they use a small-scale dataset to train the pruned model through knowledge distillation to restore its accuracy. Surprisingly, this process not only saves money but also improves the model's performance!
In practical tests, NVIDIA's research team achieved great results on the Nemotron-4 model family. They successfully reduced the model size by 2 to 4 times while maintaining similar performance. More excitingly, the 8B model outperformed other well-known models such as Mistral7B and LLaMa-38B in multiple metrics, and it required 40 times less training data and 1.8 times lower computational costs during training. Imagine what this means? More developers can experience powerful AI capabilities with fewer resources and costs!
NVIDIA has open-sourced these optimized Minitron models on Huggingface for everyone to use freely.
