Models reference

All official models on ollama.com start with a max context size of 2048 tokens with some exceptions. To increase that to 12345 tokens you would create a modelfile like this:

FROM sourcemodel
PARAMETER num_ctx 12345

Then create the new model and optionally publish it.

model name	parameters	default context size	max context size	Mem for full context	Full Context Model
gemma 2	9 billion	4096	8192	?	m/gemma2
gemma 2	27 billion	4096	8192		m/gemma2 27b
llama3	7 billion	2048	8192	?	m/llama3
qwen2	7 billion	2048	32768		m/qwen2
