TinyLlama Performance & Benchmarks
TinyLlama, a state-of-the-art machine learning model, stands out for its remarkable efficiency and speed, particularly in training and inference processes. Our latest benchmarks reveal the exceptional performance of TinyLlama, especially when compared to other models in the industry.
Training Speed and Efficiency
The core achievement of TinyLlama lies in its training speed. Thanks to a series of advanced optimizations, TinyLlama achieves a throughput of 24k tokens per second per A100-40G GPU. This impressive figure translates to 56% model flops utilization without activation checkpointing, and we anticipate even better performance on A100-80G GPUs. This high throughput means that training a model like TinyLlama, which has 1.1 billion parameters and requires processing 22 billion tokens, can be completed in just 32 hours using 8 A100 GPUs.
The table below highlights the GPU hours taken for training 300 billion tokens compared to other models:
| Model | A100 GPU Hours (300B Tokens) |
|---|---|
| TinyLlama-1.1B | 3456 |
| Pythia-1.0B | 4830 |
| MPT-1.3B | 7920 |
Inference Throughput
TinyLlama not only excels in training but also demonstrates significant efficiency during inference. The model's design, featuring grouped query attention, contributes to its high speed in this phase. The following table presents some throughputs measured under different frameworks and settings:
| Framework | Device | Settings | Throughput (tokens/sec) |
|---|---|---|---|
| Llama.cpp | Mac M2 16GB RAM | batch_size=1; 4-bit inference | 71.8 |
| vLLM | A40 GPU | batch_size=100, n=10 | 7094.5 |
These benchmarks clearly indicate that TinyLlama is not only a robust model for large-scale machine learning tasks but also a highly efficient option in terms of resource utilization and speed, setting new standards in the field of machine learning and artificial intelligence.
