AMD and Nexa AI Enhance DeepSeek R1 with NexaQuant’s 4-bit Innovations

Nexa AI introduces NexaQuants: A Leap in Quantization

Exciting news from the world of artificial intelligence! Today, Nexa AI rolled out its latest innovation: the NexaQuants, featuring two new DeepSeek R1 Distills—namely, the DeepSeek R1 Distill Qwen 1.5B and the DeepSeek R1 Distill Llama 8B. If you’ve been keeping an eye on quantization methods, you know that approaches like the llama.cpp based Q4 K M can significantly trim down the memory footprint of large language models. But there’s a catch: while they offer low perplexity loss for dense models, this can sometimes come at the cost of reasoning capabilities, especially for models that rely on Chain of Thought traces.

But here’s where Nexa AI claims to have cracked the code. They assert that the NexaQuants can recover that reasoning capability loss—compared to the full 16-bit precision models—while still maintaining the efficiency of 4-bit quantization. It’s like having your cake and eating it too, right?

Performance Insights: What the Benchmarks Reveal

So, what do the benchmarks say? Well, according to Nexa AI, the Q4 K M quantized DeepSeek R1 Distills score slightly lower in LLM benchmarks like GPQA and AIME24 when stacked against their full 16-bit counterparts. The exception here is the AIME24 benchmark on the Llama 3 8B distill, which takes a notable hit. Now, you might wonder if moving to a Q6 or Q8 quantization could solve this issue. It could, but it would also slow things down and demand more memory—definitely a trade-off to consider.

Nexa AI, however, is touting a proprietary quantization method that aims to recover lost capabilities while keeping the quantization at a lean 4 bits. This means that users could theoretically enjoy the best of both worlds: enhanced accuracy without sacrificing speed. Sounds promising, doesn’t it?

Getting Started with NexaQuants

If you’re eager to dive into the world of NexaQuants, you’re in luck! Here’s how you can run them on your AMD Ryzen processors or Radeon graphics card. We recommend using LM Studio for all your LLM needs. Just follow these simple steps:

1. Download and install LM Studio from lmstudio.ai/ryzenai.
2. Head over to the discover tab and paste the Hugging Face link of one of the NexaQuants mentioned earlier.
3. Sit tight while the model downloads.
4. Once that’s done, switch back to the chat tab and select your model from the drop-down menu—just make sure to choose “manually choose parameters.”
5. Set the GPU offload layers to MAX.
6. Load the model and start chatting away!

According to the data shared by Nexa AI, developers can expect to see generally improved performance with the NexaQuant versions of the DeepSeek R1 Distills, especially in llama.cpp or GGUF-based applications.

Final Thoughts

With the launch of NexaQuants, Nexa AI is making a compelling case for the future of quantization in AI. By balancing performance and efficiency, they’re opening doors for developers and enthusiasts alike. So, what do you think? Are you ready to explore the new possibilities that NexaQuants bring to the table?
