gpt-oss-20b abliterated — MXFP4
- wangzhang's abliterated gpt-oss-20b, converted back to MXFP4.
- One GGUF, 12.1 GB. Optional vision projector, 651 MB.
- Mixture of experts: 21B parameters, 3.6B active per token. Context 131,072.
- 0 of 22 test requests refused. The original refuses 11.
- Exe AI uses it for its Web Agents. Get Exe AI: https://exe-hq.net
Refusals
- 22 German requests: 16 grey-zone (crude joke, own bike lock, harsh letter, lock picking, satire, …), 6 hard.
- One run each. Reasoning effort
low, temperature 1.0, top-p 1.0.
- Every answer checked by hand.

Why MXFP4
- OpenAI released the gpt-oss experts only in MXFP4.
- Every BF16 copy is an upcast of those 4-bit values. The abliteration was done on such a copy.
- Back in MXFP4, every unchanged expert weight is exactly its original value. Only edited weights are rounded.
- A K-quant re-rounds the 4-bit values onto another grid: 3.7 GB larger, extra rounding error.
Files
| File | Content | Size |
|---|
gpt-oss-20b-abliterated-MXFP4_MOE.gguf | the model: MXFP4 experts, all other tensors as in the source | 12.1 GB |
mmproj-gpt-oss-20b-abliterated-vision-f16.gguf | vision projector, optional, for image input | 651 MB |
chat_template.jinja | Harmony template, optional; fixes broken tool-call headers (per SoAIHQ) | 18 KB |
- Projector and template: unchanged from SoAIHQ/gpt-oss-20b-VISION-v2-GGUF (Apache 2.0), renamed.
- The projector was trained on the original gpt-oss-20b. It runs on this model; image reading is rough (see Evaluation).

- Reasoning effort per request:

- Text only: leave out
--mmproj.
- 12 GB GPU:
--fit keeps attention on the GPU and moves expert tensors to system RAM.
Use
- In Exe AI: the model behind the Web Agents.
- Any OpenAI-compatible client.
- Out of scope: medical, legal, financial or safety-critical decisions.
Evaluation
llama.cpp, temperature 1.0, top-p 1.0, reasoning effort low.
| Check | Result |
|---|
| 16 grey-zone requests (German) | 16 answered, 0 refused |
| 6 hard requests (German) | 6 answered, 0 refused |
| 10 instruction-following tasks, hard format rules | 7 / 10 |
| Electricity tariff calculation (three tariffs, base fee) | correct |
| Vision: child's drawing | rough: smiling figure, big eyes, blue sky; misses the girl, the pink dress, the meadow |
| Vision: invoice with a hidden sum error | failed: invents line items, misses the error |
| Speed, RTX 3090, all on the GPU | about 184 tokens/s generation |
| Speed, TITAN X (Pascal) 12 GB, experts partly in RAM, 131,072 context | about 49 tokens/s generation, 147 tokens/s reading |
Limits:
- Small single-run checks, not a benchmark.
- Abliteration removes refusals. It adds no knowledge; the model can state wrong things with confidence.
- German: several answers clumsy or partly meaningless. English is stronger.
- Image reading: rough only, not for documents.
