Open backends are shaking up LLM access, challenging CUDA's grip and NVIDIA's hardware moat. The debate isn't just about speed—it's about openness, cost, and who can build the future of local AI [1].
On the software side, OpenRouter is a local server-router that auto-configures the best LLM engine on any PC. Born from a push to support AMD NPUs, it now wraps more devices, engines, and OSes [2].
• FastFlowLM — an inference engine fully integrated with Lemonade for Windows Ryzen AI 300-series PCs; switch between ONNX, GGUF, and FastFlowLM models with one click [2]. • ONNX — one of the backends you can pick in Lemonade [2]. • GGUF — another backend offered by the Lemonade ecosystem [2]. • llama.cpp’s Metal backend on macOS / Apple Silicon gives local compute a familiar route [2].
For the road ahead, more engines and backends are on the roadmap, with Lemonade aiming to integrate others and expand OS support across the board [2].
Bottom line: the hardware debate—open backends vs CUDA monopoly—will shape LLM performance, cost, and access in 2025 and beyond [1][2].

CUDA needs to die ASAP and be replaced by an open-source alternative. NVIDIA's monopoly needs to be toppled by the Chinese producers with these new high vram GPU's and only then will we see serious improvements into both speed & price of the open-weight LLM world.
