Qwen3.8-27B at 144 tok/s on an M5 Max MacBook Pro

r/LocalLLaMAscore unavailable via RSSu//u/ResearchCrafty1804comments →

Meet Inco Splash, open-source inference engine, built around the model and around Apple silicon. Up to 3× the decode speed of Ollama, 2× oMLX, and almost 4× when an agent fans out into sub-agents. Requirements: M3 or newer, macOS 26.4+, 36 GB Get started with

WHY IT MATTERS
The MacBook result is a useful real-world signal for local inference rather than a lab-only benchmark.

Qwen Image 2.1 - Pre-release comparison by Sandlers.

r/StableDiffusionscore unavailable via RSSu//u/Crazy-Repeat-2006comments →

Sandlers here. Hey everyone. I was one of the lucky ones to get early access to Qwen Image 2.1, and I’m sharing a quick comparison here against other popular open-source models. The model is incredible, better than anything else on the open-source side so far.

WHY IT MATTERS
Early comparisons can reveal capability direction, but pre-release results should be treated cautiously.
