Qwen3.8-Flash-Next under fire: strong at coding, falls apart on follow-up questions in research use
rm-rf-rm · reddit · 2026-11-01
Reddit user rm-rf-rm reports disappointment with Qwen3.8-Flash-Next: solid on coding and adjacent tasks (evaluating OSS repos, downloading and running models), but weak at general research — the model "gets lost in its own maze" on a simple question about human sleep patterns. Main complaints: overly verbose, dense answers ("feels like Opus 5 distillation"), and on basic follow-ups like "are there logical inconsistencies?" or "how do we fix this?" it produces massive essays that keep "uncovering more," eroding trust. Setup: llama.cpp with UDQ4KM + MTP, sampling params copied from Qwen3.8 27B (temp 1 / top-p 0.95 / top-k 20), minimal AGENTS.md; full chat log shared publicly.
