Try other context lengths

Run it with Ollama

With Ollama installed, one command downloads and starts Devstral Small 24B:

ollama run devstral:24b

Ollama's default download is Q4_K_M (about 16.2 GB here). You have room for Q8_0, which is near-lossless: pick that GGUF in LM Studio or from Hugging Face.
