Qwen3.8 125B (6B active) Flash-Next

User reports running Qwen3.8 Flash-Next IQ3_XXS at a 700K context window on an RTX 5090 32GB with 64GB system RAM, completing a project in one continuous session without context compaction. Generation speed is given as approximately 100-120 tokens/sec, with vision disabled. The model ran with CPU offload given the 125B size on a single 32GB card. User notes possible quality degradation at extreme context lengths and estimates 1M context might be possible at around 80 tokens/sec, though untested.
