How much RAM does Solar-Open2-250B need?

Solar-Open2-250B needs about 155 GB of memory at Q4_K_M quantization with 4K context. The download itself is 151 GB; the extra covers the context cache and runtime overhead.

Can I run Solar-Open2-250B on a laptop?

Not on typical consumer hardware. Solar-Open2-250B needs 155 GB, which is beyond a normal laptop or desktop.

Solar-Open2-250B: hardware requirements

Solar-Open2-250B needs about 155 GB of memory at Q4 quantization — a 151 GB download plus room for context and overhead. That is beyond consumer hardware; use it through an API instead.

Download sizes by quantization

Lower quantization means a smaller file and less memory, at some cost to quality. Q4_K_M is the usual starting point. What is this?

Quant	Download	RAM @ 4K	RAM @ 32K	Source
Q4_K_Mrecommended	151 GB	155 GB	161 GB	estimated
Q5_K_M	177 GB	181 GB	187 GB	estimated
Q6_K	205 GB	209 GB	215 GB	estimated
Q8_0	266 GB	270 GB	276 GB	estimated

“Measured” sizes are read from published GGUF files. “Estimated” sizes are derived from the parameter count and are typically within a few percent. The RAM columns add the context cache and runtime overhead to the download size.
