ReleasePort's take
Light signalv0.5.6 fixes memory calculation for Windows iGPUs and adds GPU detection for Ryzen AI and Radeon 890M systems. Speed estimates now include confidence metadata with tok/s ranges.
Why it matters: Windows users with Ryzen AI or Radeon 890M iGPUs should test in dev to confirm accurate GPU memory detection. Speed estimate confidence metadata enables precise tok/s planning for inference workloads.
Summary
AI summaryAdded speed estimate confidence metadata, improved MoE estimates, and enhanced Windows GPU detection.
