Will it run?

MamiLens uses 112 GB as a conservative planning floor for this profile and its listed quantization. This is not measured speed. Processor, backend support, context length, memory bandwidth and other applications still affect the result.

Suggested Ollama artifact

Confirm the tag on the official page before downloading, then run:

ollama run devstral-2:123b

Start with a representative non-sensitive task. Record the exact runtime, quantization, context, load time, generation speed, memory use and answer quality.

Evidence and limits

Published context: 256K published max. The source establishes specifications; it does not guarantee that maximum context fits at the MamiLens minimum RAM floor.
