Lizzy-7B GGUF Quants

🚨 Update: Flower Labs has officially released their native GGUF quants. I highly recommend transitioning to their repository for the most stable inference and the corrected 32k context window: flwrlabs/Lizzy-7B-GGUF.

Note: During testing, I came across a bug with rope/context length issue, which has been patched in the official release. Thanks to the 250+ community members who tested this early build!

About This Repo

This repository provides llama.cpp-compatible GGUF quants of Lizzy-7B, a UK-centric 7B language model built by Flower Labs. Refer to the original model card for more details on the model.

Available Quants

File	Quant	Size	Use Case
`Lizzy-7B-f16.gguf`	F16	~14.6 GB	needs 20GB+ VRAM or CPU offload.
`Lizzy-7B-Q8_0.gguf`	Q8_0	~7.7 GB	Recommended fits 12GB VRAM with excellent context headroom.
`Lizzy-7B-Q6_K.gguf`	Q6_K	~5.9 GB	for 10GB–12GB GPUs looking to maximize context size.
`Lizzy-7B-Q5_K_M.gguf`	Q5_K_M	~5.1 GB	8GB VRAM
`Lizzy-7B-Q4_K_M.gguf`	Q4_K_M	~4.1 GB	6GB–8GB GPUs.
`Lizzy-7B-Q3_K_M.gguf`	Q3_K_M	~3.5 GB	edge devices, 4GB GPUs, or older laptops.

Hardware Tested

Hardware	Quant	n_ctx	Speed

RTX 3060 12GB	F16	4096	Slower (VRAM overflow to RAM)

Conversion Notes

1. Architecture: OLMo 2 Post-Norm Tensor Mapping

Lizzy-7B uses a Post-Norm variant of OLMo 2. The standard convert_hf_to_gguf.py script does not recognise Flower Labs tensor naming conventions (post_attn_norm, post_mlp_norm) and will fail or silently produce a broken file. The fix was to register a LizzyForCausalLM model class in the llama.cpp conversion script, subclassing Olmo2Model and overriding modify_tensors() to remap the four divergent tensor names:

python@ModelBase.register("LizzyForCausalLM")
class LizzyModel(Olmo2Model):
    def modify_tensors(self, data_torch: Tensor, name: str, bid: int | None) -> Iterable[tuple[str, Tensor]]:

        # 1. Lizzy: post_attn_norm -> llama.cpp: post_attention_norm
        if name.endswith(".post_attn_norm.weight"):
            yield (f"blk.{bid}.post_attention_norm.weight", data_torch)
            return

        # 2. Lizzy: post_mlp_norm -> llama.cpp: post_ffw_norm
        if name.endswith(".post_mlp_norm.weight"):
            yield (f"blk.{bid}.post_ffw_norm.weight", data_torch)
            return

        # 3. QK-Norms these mapped correctly via standard paths
        if name.endswith(".q_norm.weight"):
            yield (self.format_tensor_name(gguf.MODEL_TENSOR.ATTN_Q_NORM, bid), data_torch)
            return

        if name.endswith(".k_norm.weight"):
            yield (self.format_tensor_name(gguf.MODEL_TENSOR.ATTN_K_NORM, bid), data_torch)
            return

        # 4. All other tensors — pass through normally
        yield from super().modify_tensors(data_torch, name, bid)

No weights were altered. Only the tensor name metadata was remapped.

2. RoPE Scaling Factor Correction

During conversion, the script raised this warning:

The explicitly set RoPE scaling factor (config.rope_parameters['factor'] = 8.0)
does not match the ratio implicitly set by other parameters
(implicit factor = max_position_embeddings / original_max_position_embeddings = 4.0).
Using the explicit factor (8.0) in YaRN. This may cause unexpected behaviour.

The implicit factor (4.0) is mathematically derived from the model's own position embedding settings. The explicit 8.0 in the upstream config appears to be an authoring error. To produce a consistent and correctly-behaving GGUF, the factor was corrected from 8.0 to 4.0 in config.json before conversion.

This means the effective context window for these GGUFs reflects the 4.0× YaRN scaling, not 8.0×. If Flower Labs corrects the upstream config, a re-conversion would be straightforward.
