Yeah, I would appreciate if someone could make sense of the pricing differences between these models. How can a provider run DSv4F at lower cost than a 27B dense or 35B A3B model?

Does it come down to utilization and/or specific model tricks and efficiencies (attention, kv cache, etc.)?

DeepInfra prices:

Qwen 3.6 27B: $0.32 in / $3.20 out

Gemma 3 27B: $0.08 in / $0.16 out

DeepSeek V4 Flash 0731: $0.08 in / $0.18 out

Qwen 3.6 35B A3B: $0.10 in / $0.95 out

DeepSeek V4 Flash is natively FP4 MoE with very compact KV cache. Say 8 GB/s. Qwen 27B is about 60 GB/s at full FP16 precision.
