Measured on M1 Max 64GB: weight-only INT8 runs 41% slower than fp16, a hand-written Metal int8 GEMM 15.6x slower, MPSMatrix int8 3x, and MLX 8-bit 9% slower.
Tested on M1 Max 64GB ComfyUI: v0.24.1 fails to load int8_tensorwise, v0.30.1 hits the missing aten::_int_mm MPS kernel, and a dequantize patch runs slower than bf16.
Tested on M1 Max 64GB: AnimaLoraToolkit + Anima-Base crashes on torch 2.6.0 (MPS SDPA bug) but runs 300 steps clean on 2.7.1, at ~21 s/step, roughly 9x slower than an RTX 5090.
15 formats renamed to .png, then Rails 8.1.3 vs 8.1.3.1 on one attachment: SVG logged 123x45 on the vulnerable build, nothing on the patched one. Plus the matload entry point and the libvips 8.13 floor that stops boot.
M4 Mac mini postmortem: cron auth silently dead, a recall-0.19 model passing every promotion gate, 258 poisoned negatives, and a 5-config sweep to a usable trade-off.
Qwen3.8 restored 625k chars of mangled PDF text; 5 Irodori-TTS workers on one RTX 4090 gave 38h of audio at 13x realtime. Plus an 18x reasoning_effort win and the cuInit 999 check for dead RunPod hosts.
Tested Qwen3.7/3.8 web search via the OpenAI SDK: enable_search returns no URLs, Responses API web_search does, and reasoning_tokens jump 10x on search turns.
CoreS3 voice chat rebuilt on action=async: filler on job_id, 0.7s polls, gapless sentence chunks, 8.3s to first reply, plus a Key unit (U144) talk button with port auto-detect.
Tested on a CoreS3: talk into the mic, get a spoken reply. 44-byte RIFF header on the PCM buffer, HTTPClient multipart POST built in PSRAM, 12.4–13.8s sync round trips.
Tap-to-record 5s at 48kHz into PSRAM, instant playback on CoreS3. The mic/speaker swap on the shared I2S bus worked with 200ms waits; the freeze was the serial monitor's DTR/RTS reset.
3 face PNGs embedded in flash decode to sprites in 87ms. CoreS3 touch stops at y=239 so Core2-style BtnA/B/C never fire; tap, hold and flick gestures instead.
ESP32 can't join Tailscale, so a VPS PHP relay feeds the CoreS3. Chunked WAV via writeToStream, SD mounts broken by any pre-mount LCD draw, NVS volume.
