5 Best Uncensored Qwen Models You Can Run Locally on a Mac in 2026.
A benchmark of five abliterated Qwen3.5-9B models on Mac hardware shows inconsistent performance, with one model still refusing 71% of prompts despite being marketed as uncensored. This highlights the gap between model file naming conventi…
Builder angle: Builders relying on local uncensored models for research or creative workflows need to know that abliteration is not a guaranteed removal of safety filters, requiring rigorous behavioral testing before deployment.

Knowledgator Releases GLiFormer: A 575M-Parameter Encoder That Hits 91.10 F1 on Nested JSON Extraction Without Generating Tokens
Knowledgator released GLiFormer, a 575M-parameter encoder model achieving 91.10 F1 on nested JSON extraction, nearly matching GPT-5.6-luna's 91.96. Unlike generative models, GLiFormer grounds every extracted value directly in source spans…
Builder angle: Builders can achieve near-frontier performance on structured extraction with significantly lower inference costs and higher grounding reliability using encoder-only architectures.
