By Bouka, published under apache-2.0, revision 39351255a19c.

Laura is the tutor in an offline German course app for adult beginners (A1–A2). This model talks to the learner in English and teaches German with German examples. It runs on the phone, CPU only. This is a modified version of Qwen/Qwen3-4B-Instruct-2507. Changes made: a LoRA adapter (rank 16, all linear layers, 2 epochs) was trained on ~2,500–3,300 short tutoring conversations in English, merged into the weights, and the result converted to GGUF and quantised to Q4KM with llama.cpp. Distributed under the base model's Apache-2.0 licence.

Laura — German tutor in English (Qwen3 4B Instruct 2507, GGUF)

Laura is the tutor in an offline German course app for adult beginners (A1–A2). This model talks to the learner in English and teaches German with German examples. It runs on the phone, CPU only.

This is a modified version of Qwen/Qwen3-4B-Instruct-2507. Changes made: a LoRA adapter (rank 16, all linear layers, 2 epochs) was trained on ~2,500–3,300 short tutoring conversations in English, merged into the weights, and the result converted to GGUF and quantised to Q4_K_M with llama.cpp. Distributed under the base model's Apache-2.0 licence.

How the app uses it

The app does not trust the model to judge German on its own. It checks the learner's sentence with its own dictionary first and adds the verdict to the message — (Check: → „corrected sentence“ · reason) or (Check: …) — plus dictionary meanings and the chapter's rule card. The model was trained with exactly those notes and explains them; without them it is a much weaker teacher.

Evaluation

Round 5 (2 Oct 2026): Qwen3-4B-Instruct-2507 with a LoRA on 3,974 English tutor conversations (2 epochs), then a DPO step on 278 preference pairs (the earlier model's own replies that failed the app's checks, against the correct ones). Blind-graded through the full app on 40 fresh held-out conversations (154 replies): 18.2% of replies with a mistake, against 22.7% for round 3 on the same set; mistakes in the model's own text 9 against 16.

OPT was first introduced in Open Pre-trained Transformer Language Models and first released in metaseq's repository on May 3rd 2022 by Meta AI. Disclaimer: The team releasing OPT wrote an official model card, which is available in Appendix D of the paper. Content from this model card has been written by the Hugging Face team. To quote the first two paragraphs of the official paper OPT was predominantly pretrained with English text, but a small amount of non-English data is still present within the training corpus via CommonCrawl. The model was pretrained using a causal language modeling (CLM) objective. OPT belongs to the same family of decoder-only models like GPT-3. As such, it was…

Ornith

Chirp Chirp! We are introducing Ornith-1.5, a major step toward building foundation models through end-to-end self-improvement. Ornith-1.5 extends Ornith-1.0 (which was developed on top of Qwen3.5 and Gemma4 with additional continued pretraining, mid-training, and post-training) by expanding the self-improvement loop from scaffold and rollout optimization to jointly optimizing task generation, scaffold construction, and solution rollouts. Rather than relying on a fixed set of human-curated tasks and manually designed harnesses, Ornith-1.5 continuously generates new training tasks, discovers effective strategies for solving them, and improves the policy through reinforcement learning.

Full 27B-class reasoning in ternary transformer weights, for llama.cpp (CUDA, Metal, CPU) - \~5.9 GB language model (down from \~54 GB FP16) — full 27B-class reasoning on a standard laptop or a single GPU - 98.2% of FP16 intelligence retained: 84.78 average across 14 thinking-mode benchmarks — far above the conventional IQ2XXS build (72.59) at about 82% of its footprint, and within 0.4 points of UD-Q4KXL at three times the footprint - Retains thinking, reasoning, and agentic behavior deep in the sub-4-bit regime, where conventional low-bit representations collapse: math within half a point of full precision (96.57), coding level with the baseline (89.42), agentic tool calling at 74.92…

Uncensored Qwen3.8-27B, published as GGUF quantizations with the multi token prediction (MTP) head retained and verified. Refusal behaviour has been substantially reduced, not eliminated. See Measured behaviour for the numbers. Capabilities, training data, and architecture are otherwise unchanged. - Refusal directions removed with Heretic, which co minimizes refusal count against KL divergence from the base model. No handwritten refusal removal code, no finetuning, no additional training data. - Abliteration runs at bf16 (no 4 bit quantization). the resulting LoRA is merged into the bf16 base, so the published weights are not a quantized round trip. - mtp. tensors are copied verbatim from…

Ornith-1.0-9B-GGUF

Ornith

Aloha! Today, we are releasing Ornith-1.0, a self-improving family of open-source models for agentic coding. This model card documents Ornith-1.0-9B, the most lightweight member of the Ornith family, designed for efficient single-GPU deployment. Ornith-1.0-9B is a dense ~9B model (≈19 GB in bf16), so it serves comfortably on a single 80GB GPU. The recipes below stand up an OpenAI-compatible server; add --tensor-parallel-size / --tp if you want to shard across more GPUs. For a quick local test (or to script offline generation), load the model directly with Transformers. Make sure you have a recent release installed — see the Transformers installation guide; Ornith-1.0-9B requires…
