For the first time, quantized checkpoints are available in FP8, Q4 GGUF, and NVFP4 formats, enabling fully local and private execution on consumer hardware including Apple Silicon and DGX Spark. NVFP4 W4A16 delivers 1.74× the token throughput of BF16 with minimal accuracy loss, and combined harness optimizations cut average agent step time from 6.8s to 3.3s. The release also adds native function-calling protocol support for easier integration into third-party agent frameworks. ## Full article daily.dev links to this article rather than hosting it.
