Can Desktop PC · GeForce RTX 5070 Ti · 32 GB RAM run Step 5 Preview 600B-A27B?
16 GB VRAM + 32 GB RAM · 896 GB/s memory bandwidth · Step 5 Preview 600B-A27B has 600B parameters (27B active per token).
Short answer
No. This combination isn't supported.
Step 5 Preview 600B-A27B is not published in a format llama.cpp (llama-server) can load (GGUF).
The same applies to every workload we rate (chat, coding questions, coding in a repository, agentic coding and long documents): they all need at least as much memory as chat.
