Reddit user: Qwen Flash Next wins benchmarks but loses to Qwen3.8 27B on long agent tasks

A user reports that Qwen Flash Next at iq4xs quantization excels at one-shots and benchmarks, but degrades on long-running agentic assistant work versus Qwen3.8 27B — more instruction drift and hallucination, though with lower token usage. On Strata, Flash Next never hit loops, which the author counts as a win. They ask for others' experiences across agent flavors like claw/hermes.
