Public-source support evidence
Yi-1.5-9B-Chat is listed for local download in Ollama. A separately observed community Q4_K_M GGUF gives an estimated memory budget of about 8 GB; actual use depends on runtime and context settings.

MEMORY ESTIMATES
Which file should I grab?
Q8_0 · 9.4 GB observed ↗Observed artifact size plus 20% headroom and 1.5 GB runtime allowance. Fit is an estimate; compatibility, speed, context length and hardware have not been tested.

Which file should I grab?
Q8_0 · 9.4 GB observed ↗Observed artifact size plus 20% headroom and 1.5 GB runtime allowance. Fit is an estimate; compatibility, speed, context length and hardware have not been tested.
Memory estimates are the observed file size plus fixed headroom (20% plus 1.5 GB runtime allowance); real needs also depend on context length, KV cache and runtime settings. Fit is an estimate; it does not establish runtime compatibility, speed, context length, or hardware performance. Text-weights-only estimates do not include a projector or total vision memory where unknown.
Terms: a quant is a lower-precision version of the weights; GGUF is a file format used by llama.cpp and compatible apps; MLX targets Apple silicon; vLLM is a model-serving engine for NVIDIA GPUs; the KV cache is stored attention state that grows with context length. Terms explained ↗
