Qwen3.8-Flash-Next benchmarked: Swift 1.5 fine-tune shows efficiency gains

A user benchmarked the Qwen3.8-Flash-Next model using various engines and quantization methods on a Strix Halo device. The comparison focused on efficiency, particularly with the Swift 1.5 fine-tune, which claims reduced token usage with minimal accuracy loss. Results indicated that the Gufo engine with Swift 1.5 quantization achieved the fastest overall time and best performance on coding tasks, though other configurations showed strengths in different areas.
