I used Claude Code and Opus 4.7 to design and implement an LLM-first programming language named Tacit that takes advantage of what LLMs are good at and strips away unnecessary human conveniences. The Tacit toolchain provides a "primer" tha…

Thank you to the people at ik_llama and llama.cpp. It's amazing how far you've all pushed mtp and other tech so that I can run 27B and 35B Qwen3.6 models on an old gaming laptop with a RTX2060 mobile at 6GB VRAM and 32GB RAM.

I’m sharing the mistakes and failures before the wins, for two reasons: so others can avoid them, and so I learn faster. I started on the frontend and it’s now in a good place.

tl;dr - For software development, Qwen3.6 27B, 5090 gives you ~3x speed over M5 Max, letting you plow through code, while M5 Max gives you ~4x memory, letting you use higher quantization and bigger context. Which would you choose and why?

Each new model seems to surface a few recurring Tells/Tics not seen in past models. I'm curious what little things you guys are noticing while working with 4.7.
