Another milestone release of GPULlama3 from our group with significant performance and productivity enhancements! #Java #AI
🚀 gpullama3.java v0.3.0 is out!
Faster FP16 & Q8 inference on NVIDIA GPUs, smoother setup with the new TornadoVM SDKs and seamless Quarkus integration.
Also, here is a demo of @quarkus.io + @langchain4j.dev running GPU inference on NVIDIA through @tornadovm.org fully in Java, no native deps!
