Vibe Coding With A NVIDIA DGX Spark
I hooked up a NVIDIA DGX Spark to test exactly how running open-source AI models LOCALLY stacks up against frontier models like Claude Opus 4.6. We aren't trying to see if they can compete yet—we want to know exactly where the baseline is today. Today, we are putting local hardware to the ultimate test.
In this video, I take you behind the scenes of my new DGX Spark setup, connecting via SSH and Nvidia Sync to run massive models right here in my office. We benchmark Qwen 3.5 (122B), Gemma 4 (31B), and GPT-OSS (120B) using Ollama, pushing them to the absolute limit in a real vibe coding workflow inside BridgeSpace. I reveal the brutal truth about local model speeds, the massive difference between 8B and 120B parameter models, and officially launch the new DGX Spark Bench on BridgeBench.ai. Are local open-source models ready to replace your cloud IDE stack? Let's find out.

What is BridgeMind?
BridgeMind is the operating system for the agentic future. We are building a fully integrated suite of vibe coding tools designed to orchestrate complex AI workflows, all powered by a highly optimized PostgreSQL database architecture:
BridgeMCP: Our Model Context Protocol server that acts as the central nervous system for agentic memory and context.
BridgeSpace: The AI-native Agent Development Environment (ADE) and cloud IDE for managing swarms.
BridgeVoice: High-velocity voice-to-text engineered specifically for coding at the speed of thought.
BridgeCode: The core agentic engine powering our autonomous coding workflows.
