NVIDIA (Oct 16) details RTX Spark as a single-machine coding-agent workstation: decision models in llama.cpp/Unsloth choose next actions up to ~200x faster than long reasoning loops; HydraFusion prompt router escalates only when local models aren’t enough; GitHub Copilot gains Windows ML + llama.cpp local backend; Junie Local and Pi optimized. Pair with open Nemotron Bolt 74B-A9B 24GB for on-device agents via Ollama/vLLM/LM Studio.
Open-weight 27B decision model answers many choice/noul/score questions about one state in a single noncausal joint request (Decision Index ~68; vision ~77), with a calibrated readout head and optional fast packing path—pattern for cheap agent routing/tool selection.
