Quality is the published perplexity delta against f16 weights. Max context assumes an f16 KV cache; q8_0 roughly doubles it. This model interleaves sliding-window layers (1024 tokens, 1 global in 6), which is why its cache barely grows with context.
How to run it
$ ollama pull gemma3:12b $ OLLAMA_CONTEXT_LENGTH=8192 \ ollama run gemma3:12b
The default. One binary, a model registry, an OpenAI-compatible port. More on Ollama.
