How to use

These bundled files are too large to run on Windows. Use a separate llamafile binary with the source GGUF files, as shown in the llamafile docs.

1. Download the llamafile (e.g. Q4_K_M).

2. Open a terminal on Linux or macOS.

3. Grant execute permission.

   chmod +x orcarouter_Qwen3.8-27B-Uncensored-Q4_K_M.llamafile
   

4. Run the file.

   bash orcarouter_Qwen3.8-27B-Uncensored-Q4_K_M.llamafile
   
   # Or run directly if your system supports it.
   ./orcarouter_Qwen3.8-27B-Uncensored-Q4_K_M.llamafile
   

   • CLI: Chat directly in the current terminal.
   • Web UI: Open localhost:8080 in your browser.
   • API: Connect an OpenAI-compatible client to http://127.0.0.1:8080/v1.
     • The chat endpoint is /v1/chat/completions.
     • The server supports 4 parallel requests by default.

5. Press Control-C to stop the process.

6. For more details, run with --help or read the llamafile docs.

   bash orcarouter_Qwen3.8-27B-Uncensored-Q4_K_M.llamafile --help

Other variants:

• Qwen3.8 27B
• Heretic ARA Uncensored (Best Performance)
• OrcaRouter Uncensored (This one, Best Uncensored)
• Ultra Heretic Uncensored
• Huihui Uncensored
• OBLITERATUS Uncensored
• Blackfrost Uncensored

The suggestions are based on imperfect benchmarks and should not be trusted blindly. Try the variants yourself with your own use case.

All data came from the Abliterlitics review (snapshot), which also contains more detailed analysis of more uncensored model variants. I am not the author, nor did I replicate the experiments myself.
