 ```bash
 llama-embedding -hf jinaai/jina-embeddings-v4-text-matching-GGUF:F16 --pooling mean -p "jina is awesome"  2>/dev/null
 ```

+Note, v4 is trained with Matryoshka embeddings, and converting to GGUF doesn't break the Matryoshka feature. Let's say you get embeddings with shape `NxD` - you can simply use `embeddings[:, :truncate_dim]` to get smaller truncated embeddings. Note that not every dimension is trained though. For v4, you can set `truncate_dim` to any of these values: `[128, 256, 512, 1024, 2048]`.
