Gemma 3 QAT Insane Speed Boost vs FP16?! Google AI's KILLER 27b

The video discusses the advancements in Google AI’s Gemma 3 model, particularly its Quantization Aware Training (QAT) version, which significantly reduces model size and improves speed compared to the FP16 version. While both models perform well in various tasks, the QAT model demonstrates impressive efficiency and potential for general-purpose applications, making it a strong candidate for users with limited hardware resources.

In the video, the presenter explores the latest advancements in the Gemma 3 model, specifically focusing on the Google AI’s Quantization Aware Training (QAT) version. This model significantly reduces the size from 54 GB in the previous BF16 format to just 14 GB in the QAT format, allowing it to run efficiently on smaller GPUs. The presenter conducts informal tests comparing the QAT version with the FP16 version, highlighting the impressive speed and performance differences between the two models.

During the testing, the presenter notes that the QAT model achieves a higher tokens-per-second rate compared to the FP16 model, with 36 response tokens per second and 174 prompt tokens for QAT, versus 14 response tokens and 97 prompt tokens for FP16. Both models are set up with the same parameters, ensuring a fair comparison. The presenter emphasizes the potential of QAT to perform comparably to BF16 models, which raises interest in its practical applications for users with limited hardware resources.

The presenter then tests the models’ ability to follow instructions and generate responses. For example, when asked to write a sentence about a cat and analyze specific details, both models perform well, but the QAT model provides a more detailed justification. However, when tasked with recalling the first 100 decimals of pi, the FP16 model falters while the QAT model succeeds. This inconsistency highlights the strengths and weaknesses of each model in different scenarios.

Further tests involve analyzing images and interpreting emotions displayed in photographs. The QAT model struggles to accurately describe the emotions in one image, while the FP16 model performs better in another instance. Despite some misses in the QAT’s responses, the presenter notes that the overall performance is impressive for a model that requires significantly less computational power, making it a strong candidate for general-purpose tasks.

In conclusion, the presenter expresses enthusiasm for the advancements made with the QAT model, suggesting it could serve as an excellent generalist AI assistant. While it may not excel in specialized tasks, its efficiency and performance make it a valuable tool for everyday applications. The video encourages viewers to engage with the content, share their thoughts, and explore the potential of QAT in the evolving landscape of AI technology.
