Laguna XS.2 - GGUF Quantizations

First-ever GGUF conversion of poolside/Laguna-XS.2, produced as part of the Poolside Research Hackathon.

Laguna XS.2 is a 33.4B total parameter (3B activated) Mixture-of-Experts model built for long-horizon agentic coding. These GGUF files enable local deployment via llama.cpp and compatible inference engines.

⚠️ Inference status: Full CPU/GPU inference requires 6 C++ patches to llama-model.cpp (documented below). All benchmarks were run using vLLM on the original BF16 checkpoint.

Available Files

Filename	Quant	Size	Notes
Laguna-XS.2-F16.gguf	F16	63 GB	Fixed source (experts F16, attention F16)
Laguna-XS.2-Q4_K_M.gguf	Q4_K_M	~60 GB	Attention Q4, experts F16

Note on quantization sizes: llama.cpp does not quantize 3D MoE expert tensors. Attention/embedding weights are fully quantized; expert weights remain F16. This is a known llama.cpp limitation for large MoE models. Proper small quants (~18GB Q4_K_M) require upstream llama.cpp changes.

Benchmark Visualizations

Architecture - Key Differences from Mixtral

Feature	Laguna XS.2	Mixtral
Routing	Sigmoid	Softmax
Shared expert	Yes (always runs)	No
Routed scaling	2.5×	1.0×
Attention	Interleaved SWA/GA 3:1	Global only
RoPE θ	500k (GA) / 10k (SWA)	Single value
Per-head gating	Softplus g_proj	None
Expert count	256, top-8	8, top-2
Q-heads per layer	48 (GA) / 64 (SWA)	Uniform

Custom GGUF Metadata Keys

Key	Value
`laguna.attention.layer_types`	`[0,1,1,1,0,...]` — GA=0, SWA=1
`laguna.attention.heads_per_layer`	`[48,64,64,64,48,...]`
`laguna.rope.theta_swa`	`10000.0`
`laguna.rope.partial_rotary_factor`	`0.5`
`laguna.moe.routed_scaling_factor`	`2.5`
`laguna.moe.sigmoid_routing`	`true`
`laguna.attention.softplus_gating`	`true`

C++ Patches for llama.cpp Inference

Sigmoid routing: ggml_soft_max → ggml_sigmoid in MoE router
Routed scaling: multiply routed output by laguna.moe.routed_scaling_factor (2.5)
e_score_correction_bias: add to router scores before top-k
Dual RoPE θ: use laguna.rope.theta_swa for SWA layers
Partial RoPE: rotate only 50% of head_dim on GA layers
Softplus g_proj gating: softplus(g_proj(x)) per head after attention, before o_proj

Conversion

Registration in conversion/__init__.py:

"LagunaForCausalLM": "laguna"

The conversion script (conversion/laguna.py) handles:

Stacking 256 individual expert weights → 3D tensors [256, dim_in, dim_out]
Per-layer variable Q-heads (48 GA / 64 SWA)
Sigmoid router, shared expert, g_proj, e_score_correction_bias
All Laguna metadata as custom GGUF keys
