Instella-MoE-16B-A3B-Think GGUF

GGUF quantizations of AMD's Instella-MoE-16B-A3B-Think, converted and optimized for local inference with llama.cpp-compatible runtimes that support the Instella-MoE architecture.

Overview

This repository provides a full collection of GGUF quantizations for [amd/Instella-MoE-16B-A3B-Think](la-MoE-16B-A3B-Think.

Instella-MoE-16B-A3B-Think is a Mixture-of-Experts reasoning model featuring approximately 16B total parameters with ~3B active parameters per token, designed for efficient high-quality inference while maintaining strong reasoning, coding, and instruction-following capabilities.

These GGUF files were generated to enable:

  • Local inference
  • CPU deployment
  • GPU-accelerated llama.cpp inference
  • Edge and workstation deployments
  • Quantized execution with reduced memory requirements
  • Reasoning-focused workloads

⚠️ Important Compatibility Notice

Instella-MoE is not currently supported by upstream llama.cpp at the time these GGUFs were produced.

The model introduces architecture components beyond standard DeepSeek-V3 implementations, including:

  • Gated Attention
  • FarSkip dual-residual connections

These quantizations were generated using the community fork:

https://github.com/csabakecskemeti/llama.cpp

Branch:

instella-moe

This fork implements:

  • InstellaMoEForCausalLM
  • Gated attention runtime support
  • FarSkip support
  • GGUF export support for Instella-MoE

As a result, these files currently require:

llama.cpp (instella-moe branch)

or any future upstream release that merges full Instella-MoE support.

BF16 Conversion

The original model weights were converted directly into GGUF BF16 format using the Instella-MoE-enabled llama.cpp conversion tools.

Importance Matrix Generation

Importance matrix calibration was generated using:

Salesforce/wikitext
wikitext-2-raw-v1

A lightweight calibration dataset was used to optimize IQ quantization quality while remaining practical on constrained hardware.

IQ Quantization

IQ quant variants were produced using llama.cpp's importance-matrix-aware quantization pipeline.

Build Environment

These GGUFs were generated on a resource-constrained environment designed to maximize reproducibility.

System Constraints

  • ~15 GB RAM
  • No swap
  • ~109 GB temporary storage
  • 4 CPU cores

Because the BF16 GGUF is approximately:

~32 GB

the importance matrix was computed from a smaller intermediate quantization to avoid memory exhaustion while still producing high-quality IQ variants.

Repository Notes

Generation workflow includes:

  • Automatic resume support
  • Upload tracking
  • Incremental quant generation
  • Disk-space-aware cleanup
  • Fault-tolerant upload recovery

Each quant is generated, uploaded, and safely removed locally before proceeding to the next file.

Prompt Format

Instella-MoE-16B-A3B-Think is an instruction-tuned reasoning model.

Typical usage:

User: Explain the difference between MoE and dense transformers.

Assistant:

For best results:

  • Use clear instructions
  • Allow sufficient context length
  • Enable model reasoning when your frontend supports it
  • Use lower temperatures for factual tasks
  • Use higher temperatures for creative tasks

Performance Expectations

General guidance:

Quant Quality Memory Usage
Q2_K Lowest Minimal
Q3_K_M Good Low
Q4_K_M Very Good Moderate
IQ4_XS Excellent Moderate
Q5_K_M Excellent Higher
Q6_K Near BF16 High
Q8_0 Maximum Very High
BF16 Reference Highest

Actual results depend on:

  • Prompt complexity
  • Context length
  • Hardware
  • Backend implementation
  • Future Instella-MoE runtime optimizations
