User reports Qwen3.8 27B at around 20 t/s sustained on an M5 Pro 64GB, with about 30 t/s in the first 2-4k tokens. User finds it unbearably slow, possibly because the model thinks so much. User also tried antirez's DS4 with DeepSeek V4 Flash and gets around 8 t/s sustained, which they call slow and basically unusable.

User reports 10-17 t/s in SSD streaming mode. Setup keeps routed experts partly in RAM cache and pulls them from the GGUF on cache misses. Experts and output head are Q8_0, while router, embeddings and V4 auxiliary blocks are FP16.

User asks which model to use for agentic coding. User reports DeepSeek V4 Flash at 10-11 t/s with 1M context, and Qwen3.8 27B at 15-16 t/s with FP8 quants.

User reports 2.04 t/s with an 8 GB expert cache and 1.23 t/s with a 32 GB expert cache, streaming from SSD. Speculative decoding and prefetch both decreased throughput. Codebook 2-bit quantization failed the quality gate.
