I use it actively with deepseek and vscode continue extension. For integrated graphics your memory speed and number of channels will greatly affect your inference speed. 06 ms / 665 runs ( 33. Vulkan Scoreboard for Llama 2 7B, Q4_0 (no FA) I got the latest llama. 4. cpp has no ui so I'd wait until there's something you need from it before getting into the weeds of working with it manually. The costs to have a machine of running big models would be significantly lower. All the Llama models are comparable because they're pretrained on the same data, but Falcon (and presubaly Galactica) are trained on different datasets. Try classification. 1, and llama. cpp: Improve cpu prompt eval speed (#6414) Mar 28, 2023 · For llama. But I have not tested it yet. cpp go 30 token per second, which is pretty snappy, 13gb model at Q5 quantization go 18tps with a small context but if you need a larger context you need to kick some of the model out of vram and they drop to 11-15 tps range, for a chat is fast enough but for large automated task may get boring.
