Qwen-Image-2.1 on a 32GB Mac: The Biggest GGUF Is the Fastest
Qwen-Image-2.1 cut its image generator from 20.4B to 7B parameters. Measured at four quantizations on an Apple M5 32GB: Q8_0 is the fastest and the most faithful, native transparency works only at enough steps, and the license restricts the model but says nothing plain about your images.


Quantizing the KV Cache Made It Faster, Not Just Smaller
The usual framing is memory for quality. Measured across three configurations on one Apple M5 32GB, an 8-bit KV cache cut memory 36% at 64K and raised generation speed 52% — and across every output compared, it did not change what the models wrote.


Long Context on a 32GB Mac: Four Local LLMs, Measured to 128K
Four local models measured at 4K to 128K context on one Apple M5 32GB. Two of them are the same size; at 64K one runs 3.3x faster on half the memory. At 128K a 12B model holds the window in the same memory as a 3B one, and faster. The difference is sliding-window attention.
Running TRELLIS.2 on a Mac (3/3): The Optimizations That Actually Won
The optimizations that survived measurement: load time cut 5x, mesh extraction 67x, and a sixth twist that overturned my own conclusion about MPS attention.
Running TRELLIS.2 on a Mac (2/3): Five Bottlenecks I Guessed Wrong
Five confident guesses about where the Apple Silicon port was slow — and how honest measurement killed every one, plus the profiling methodology that made the numbers trustworthy.
Running TRELLIS.2 on a Mac (1/3): Porting a CUDA-Only Image-to-3D Model to Apple Silicon
How I got Microsoft's CUDA-only image-to-3D model (TRELLIS.2) to run on Apple Silicon: an idempotent patcher, swapping the CUDA kernels out one by one, and the first generation.


One Session with Claude Fable 5 Un-Stuck My Abandoned Three.js Game
My son-inspired Three.js endless runner sat abandoned for nine months: no physics, horror-movie visuals, no real gameplay. One session with Claude Fable 5 produced 48 commits and solved exactly the systems that had me stuck — then export controls took the model offline that same day.
