TurboLaguna-XS

Canonical artifact: Laguna-XS-2.1-TQ3_4S

TurboLaguna-XS is the TurboQuant GGUF build of Poolside's Laguna XS 2.1 — a sigmoid-routed mixture-of-experts coding model with 256 experts per layer, a shared expert, QK-norm, and hybrid YaRN/sliding-window RoPE.

The exact file and runtime artifact name is:

Laguna-XS-2.1-TQ3_4S.gguf

Required Runtime

This model uses the custom TQ3_4S tensor type. Stock llama.cpp builds cannot load it. You must use the TurboQuant runtime fork:

turbo-tan/llama.cpp-tq3

This is a standard (non-MTP) model — no draft-MTP flags are needed.

Parent Model

Upstream parent: poolside/Laguna-XS-2.1-GGUF
Source quant: Laguna-XS-2.1-BF16.gguf (63.8 GB, 16.01 bpw)
Format conversion and TurboQuant packaging: turbo-tan/llama.cpp-tq3

Files

File	Size	Notes
`Laguna-XS-2.1-TQ3_4S.gguf`	16 GB (4.05 bpw)	Main model — 678 tensors, 40 layers × 256 routed experts
`thumbnail.png`	—	Model card image
`benchmark.png`	—	Benchmark summary

Quantization Recipe

Quantized from the official BF16 GGUF using the standard TQ3_4S recipe:

./build/bin/llama-quantize --allow-requantize \
  --output-tensor-type q6_K \
  --token-embedding-type q6_K \
  Laguna-XS-2.1-BF16.gguf \
  Laguna-XS-2.1-TQ3_4S.gguf \
  TQ3_4S

Tensor policy:

Routed experts, attention projections, shared experts → tq3_4s (4.0 bpw)
Token embeddings, output head → q6_K
Norms, gates, biases → f32 (untouched)

Result: 63.8 GB → 16 GB (3.98× compression), 42% smaller than Poolside's own Q4_K_M (20 GB).

Recommended Runtime

./build/bin/llama-server \
  -m Laguna-XS-2.1-TQ3_4S.gguf \
  --host 127.0.0.1 --port 8080 \
  -c 8192 -np 1 -ngl 99 -fa on \
  --reasoning off --jinja

Build note:

-fa on is the runtime flash-attention flag, not the CMake GGML_CUDA_FA_ALL_QUANTS build flag.
