PORTABLEMIND
Legacy build

Firmware 1.2

Switched to quantized model formats to halve boot time and reduce RAM footprint on 8 GB machines.

// Highlights

Quantized Models

Models swapped to quantized variants — comparable quality, half the RAM, faster first-token latency.

// What changed
  • Quantized model pipeline (Q4/Q5 variants).
  • Cold-boot time reduced by ~50% on typical hardware.
  • 8 GB RAM machines now run comfortably with the standard preset.
// Hardening
  • Memory pressure handling for sustained chat sessions.
  • Cleaner shutdown when USB is ejected unexpectedly.
