Local 2-bit quantized model catches a logic trap that frontier DeepSeek V4-Flash fell for
HolidayBit143 · reddit · 2026-09-30
A Redditor ran a 10-point diagnostic (reasoning traps, Python semantics, SQL, instruction following) on a local Q2K quantization of Nex-N2.5-mini, a fine-tuned Qwen3.5-MoE. On item #4, DeepSeek V4-Flash wrongly assumed a statement was false, while the 2-bit local model recognized the statement set was logically consistent and refused the leading question — scoring 10/10. The author stresses this is anecdotal: it shows heavy quantization can preserve 'reasoning circuits', not that Q2 models beat frontier models generally.
