v1.0.22 — x64 installer (.exe or .msi)
| OS | Windows 10 (64-bit) or newer — Windows 11 recommended |
| Architecture | x86_64 (64-bit) |
| RAM | 4 GB minimum — 8 GB recommended |
| Disk space | 300 MB free |
| USB | USB port for serial communication; driver depends on adapter (e.g. CH340, CP2102, FTDI) |
| WebView2 Runtime | Preinstalled on Windows 11; automatically installed on Windows 10 if missing |
The serial terminal, macros, triggers, scripting, and programmer work without any GPU. Local AI models that are powerful enough for ComIO.Studio (code generation, log analysis, MCU debugging) require a high-VRAM GPU. Smaller models (under ~13B parameters) are too weak for reliable assistance — we do not recommend them.
| GPU | NVIDIA (CUDA) or any Vulkan-compatible GPU (AMD recent, Intel Arc) |
| Minimum (usable assistant) |
16 GB VRAM — runs gpt-oss 20B (Q4 quantization), Gemma 4 26B (low quant) |
| Recommended | 24 GB VRAM (e.g. RTX 3090 / 4090) — runs Gemma 4 31B comfortably (Q4-Q5) |
| High-end | 48 GB+ VRAM (RTX 6000 Ada, dual 24GB) — 70B-class models, large context |
| Drivers | NVIDIA: GeForce driver 520+ (CUDA 12 included) AMD/Intel: Vulkan-compatible driver |
CPU-only is technically possible but extremely slow for 20B+ models — dedicated GPU is strongly recommended.
