Efficient model
- Definition
- A model designed to deliver strong performance at a fraction of the compute cost of frontier models, through architectural innovations, aggressive distillation, or better training data curation. Efficient models prioritize the performance-per-dollar ratio.
- Why it matters
- Not every AI use case needs a frontier model. For the vast majority of production workloads, classification, extraction, summarization, and simple Q&A, an efficient model delivers equivalent quality at 10-100x lower cost. The efficient model segment is where most of the real-world AI deployment happens, even though frontier models get the headlines. For engineering leaders, choosing the right model size for each use case is one of the highest-ROI decisions you can make. Over-specifying model capability wastes money; under-specifying degrades user experience. The art is in matching model capability to task complexity.
- In practice
- Microsoft's Phi-3 family achieved GPT-3.5-level performance with only 3.8B parameters, primarily through superior data curation. Google's Gemma 2B and 7B models target edge deployment with strong performance per parameter. Anthropic's Claude 3 Haiku was specifically designed as an efficient model for high-volume, latency-sensitive use cases. Mistral's 7B model punched far above its weight when it launched in 2023. The efficient model market is now the fastest-growing segment: companies running thousands of AI calls per minute are choosing 7-14B parameter models over frontier models, saving 90%+ on inference costs while meeting quality requirements.

Distillation
The process of training a smaller, cheaper model to mimic the behavior of a larger, more capable one. Distillation is how companies ship AI to edge devices and reduce inference costs without sacrificing too much quality.
Quantization
Reducing the numerical precision of a model's weights (e.g., from 32-bit to 4-bit) to shrink its memory footprint and speed up inference. Quantization makes it possible to run large models on consumer hardware.
Inference cost
The expense of running an AI model in production, typically measured per million tokens. Inference costs have dropped 10-100x in the past two years, enabling new business models and use cases.
Frontier model
The most capable AI model available at any given time, representing the current state of the art. Frontier models push the boundaries of what AI can do and are typically the most expensive to train and run.
