GPT-OSS 20B F16 GGUF

This is a high-quality F16 GGUF conversion of the GPT-OSS 20B model, optimized for llama.cpp inference.

Model Details

• Model Type: GPT-OSS (Mixture of Experts)
• Parameters: 20.91B total, 1.8B active
• Precision: F16 (16-bit floating point)
• File Size: 12.83 GiB
• Context Length: 131,072 tokens
• Experts: 32 total, 4 active per token
• Architecture: Sliding window attention with expert routing

Key Features

• ✅ Fully Functional: All 459 tensors intact, including mxfp4 expert weights
• ✅ High Quality: F16 precision maintains model performance
• ✅ Complete MoE Support: Expert routing and gating fully preserved
• ✅ Extended Context: 131K token context window with YARN scaling

Usage with llama.cpp

# Download the model
huggingface-cli download davidfred/gpt-oss-20b-f16-gguf gpt-oss-20B-F16.gguf


## Hardware Requirements

- **Minimum RAM**: 16 GB (recommended: 24 GB+)
- **CPU**: Multi-core recommended (tested on 8 vCPU)
- **Storage**: ~13 GB free space
- **OS**: Compatible with llama.cpp (Linux, Windows, macOS)

## Performance Notes

- Efficiently runs on CPU-only setups
- Utilizes mixture of experts for optimal parameter efficiency
- Supports both interactive and batch inference modes
- Compatible with llama.cpp server mode for API access

## Model Origin

Converted from the original GPT-OSS 20B model using llama.cpp conversion tools. This F16 GGUF preserves all model capabilities while providing efficient inference performance.

## License

Apache 2.0 - Same as the original GPT-OSS model.
