=== Find a suitable model that fit in RAM ===
https://ollama.com/search list model size on disk, not on VRAM.

Also find a model that can think and run tools ( this may help https://www.canirun.ai/ )

Model take VRAM size, but context size also. As stated here, we may have to increase context size to 16k-32k.

https://opencode.ai/docs/fr/providers/#ollama

==== Increase model's context size ====
<syntaxhighlight lang="bash">
ollama run qwen3.5:2b

>>> /set parameter num_ctx 32768

Set parameter 'num_ctx' to '32768'

>>> /save qwen3.5:2b-32k

Created new model 'qwen3.5:2b-32k'
</syntaxhighlight>

==== Check if it fits in VRAM ====
Run the model:<syntaxhighlight lang="bash">
ollama run qwen3.5:2b-32k
</syntaxhighlight>Then check CPU vs GPU usage. It should be 100% GPU to stay fast<syntaxhighlight lang="bash">
ollama ps
NAME ID SIZE PROCESSOR CONTEXT UNTIL
qwen3.5:2b-32k 094e78c5fe51 5.1 GB 100% GPU 32768 4 minutes from now
