Qwen3.8-Unleashed is an open-weight language model from outsourc-e, listed in the AxForge catalogue. AxForge can bring it up on EU-owned hardware for you on request — with the licence handled where one is required.
About
Qwen 3.8 27B UNLEASHED — GGUF ### ✅ All 9 tiers verified and live (2026-08-21) UD-IQ1M and UD-IQ2S were briefly published broken, then withdrawn, and are now rebuilt, load-tested, and back. If you downloaded either before 2026-08-21 22:00 UTC, re-download. No other tier was ever affected. If you are quantizing this model yourself, this is the part worth reading. Upstream builds low-bit tiers with a different architecture, not just different bit widths: | | Q3KXL and above | IQ1M / IQ2S | |---|---|---| | tensors | 506 | 498 | | highest block | 64 (MTP head at q6k) | 63 (MTP pruned) | | blockcount | 65 | 64 | | nextnpredictlayers | 1 | 0 | Their imatrix has 496 entries because it matches that pruned topology. Quantizing a 65-block f16 against it fails with Missing importance matrix for tensor blk.64.attnk.weight. --prune-layers 64 alone is not enough — it removes the tensors but leaves the model declaring an MTP head, so loading dies on blk.63.nextn.ehproj.weight not found: a structurally valid file containing an unloadable model. You also have to rewrite the metadata: bash llama-quantize --imatrix <imatrix --tensor-type-file IQ1M.txt \ --prune-layers 64 \ --override-kv qwen35.blockcount=int:64 \ --override-kv qwen35.nextnpredictlayers=int:0 \ model-f16.gguf out.gguf IQ1M 12 Every file here is now gated on exit code → magic bytes → an actual load test before upload. Header checks alone let two broken builds through; only loading the model catches it. Uncensored Qwen3.8-27B, quantized with per-tensor dynamic bit allocation. Most uncensored GGUFs are uniform quants — every layer gets the same treatment. These use a per-tensor type map, so sensitive tensors keep precision while tolerant ones compress hard. The result: a Q3 that outperforms a Q4 3.3 GB larger, with full 250k-token retrieval. Provenance, stated plainly. The per-tensor quant map was extracted from unsloth/Qwen3.8-27B-GGUF (Unsloth Dynamic 3.0) by reading the tensor-type table from their published files, then applied to JonathanColetti/Qwen3.8-27B-Uncensored weights with that repo's imatrix. The recipe is Unsloth's work, not ours — we did not independently derive it. All upstream projects are Apache 2.0.

Using it via the API
Once AxForge deploys qwen3-8-unleashed for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (qwen3-8-unleashed below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/chat/completions \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"qwen3-8-unleashed","messages":[{"role":"user","content":"Hello"}]}'
