After lots of more testing using GLM Air I've also found that the bf16 version actually performs much better for tool calling over long context (e.g. beyond 64k). There are way more issues with quantized models, even at 8-bit. Anyone seeing similar results?

So far GLM 4.5 (Air) is my favorite local model for code auditing tasks. It's really good at instruction following and handling long context prompts. gpt-oss 120b is good too, but reasoning effort has to be set to Medium (e.g. @lmstudio sets it to Low by default).

Friday was my last day at Trenchant/Azimuth. It has been an epic journey (when eta Netflix series) where I’ve had the opportunity to work with some incredibly talented people. A very special thanks goes out to @hzon and @mdowd who decided to give this Norwegian guy a chance.
