Local agents hit power tier with Qwen3-Coder-Next

The 128GB RAM upgrade is the 2026 milestone that finally makes local agentic loops reliable by providing the headroom required for massive 256K+ context windows. Hardware synergy between 48GB of VRAM and 128GB of system RAM keeps active parameters of models like Qwen3-Coder-Next entirely on-GPU while system RAM acts as a buffer for AST-aware codebase indexing. Moving from dense models to sparse Mixture-of-Experts eliminates the looping failures seen in earlier local setups by providing superior tool-calling logic and error recovery. OpenCode paired with the Oh-My-OpenAgent plugin's Sisyphus orchestrator is the current gold standard, coordinating specialized sub-agents like Librarian for search and Oracle for code review. This hardware tier crosses the utility threshold where local agents match cloud performance for complex, multi-file refactors without the latency or privacy concerns of hosted APIs.
