Rise of Smaller Language Models, Advantages and Limitations

Context: Recent advancements in Artificial Intelligence (AI) have seen a shift from scaling up massive models to focusing on smaller, more efficient models.

About Small Language Models (SLMs)

  • SLMs are artificial intelligence (AI) models that can process, understand and generate human language.
  • SLMs also work on a neural network-based architecture known as the transformer model.
  • SLMs are cheaper, faster to train and require fewer computational resources compared to LLMs.

Advantages of SLMs

  • Accuracy: SLMs can provide higher quality and more accurate results than LLMs.
  • Privacy: SLMs can perform tasks locally, such as text prediction, voice commands, and translation without sending data to the cloud.
  • Specialization: SLMs are designed for specific use cases rather than the broad general intelligence goals of LLMs.
  • Sustainability: SLMs have lower energy consumption, which contributes to improved sustainability.
  • On-Device Functionality: Apple Intelligence integrates SLMs into iPhones and iPads, balancing performance with device constraints.

Limitations of SLMs

  • Inferior Performance on Complex Tasks:
    • SLMs struggle with benchmarks like coding, logical reasoning and solving intricate problems.
    • They cannot yet match LLMs in addressing challenges requiring broad general intelligence.
  • Factual accuracy: SLMs may not be able to store much factual knowledge, which can lead to factual inaccuracies

Industry Adoption

  • Google DeepMind released Gemini Ultra, Nano, and Flash models.
  • OpenAI launched the GPT-4o mini, and Meta introduced Llama 3 models.
  • Amazon-backed Anthropic AI released Claude 3 and Haiku.
  • Indian initiatives: Visvam (IIIT Hyderabad) and Sarvam AI.
