2-bit quantized versions of Qwopus3.6-27B-Coder, calibrated on real agentic coding logs, achieve a 63% pass rate on SWE-rebench. The IQ2_M quant outperforms non-calibrated versions and rivals Q5_K_M in pass rate despite being half the size, with improved robustness to loops and faster decoding due to a bundled MTP.
