Key Points

A Reddit user reports strong real-world performance from Qwen 3.6 27B on a local 5090 Laptop with 24GB VRAM, claiming it passes their tool-calling and data-science benchmarks.
They say the model is particularly effective for PySpark/Python workflows and data transformation debugging, to the point that they plan to cancel cloud subscriptions.
The user is running the model via llama.cpp using a quantized q4_k_m at q4_0, while still exploring further optimization options.
The post frames the result as highly use-case-dependent, noting it may not generalize to other professions or tasks.
Overall, the article functions as an early user validation signal for local deployment of a 27B-class model on relatively modest VRAM.

I have a 5090 Laptop from work, 24GB VRAM.

I have been testing every model that comes out, and I can confidently say I’ll be cancelling my cloud subscriptions.

All my tool call and data science benchmarks that prove a model is reliably good for my use case, passed.

It might not be the case for other professions, but for pyspark/python and data transformation debugging it’s basically perfect.

Using llama.cpp, q4_k_m at q4_0, still looking at options for optimising.
