+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the

+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,

+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# Astrea R8 Chat 9B — GGUF
+
+Official text-only GGUF builds of
+[Altworld/Astrea-R8-Chat-9B](https://huggingface.co/Altworld/Astrea-R8-Chat-9B),
+a compact conversational and creative-writing model built on Qwen3.5-9B.
+
+**[Try Astrea](https://chat.altworld.io)** ·
+**[API](https://altworld.io/developer)** ·
+**[Documentation](https://astrea.altworld.io/docs/)**
+
+## Files
+
+| Quant | Size | Use case |
+|---|---:|---|
+| **Q5_K_M** | 6.02 GiB | Recommended balance of quality and size |
+| Q4_K_M | 5.24 GiB | Smaller and faster; passed the same chat-routing smoke tests |
+| Q6_K | 6.85 GiB | Higher fidelity |
+| Q8_0 | 8.87 GiB | Highest-fidelity quant in this repository |
+
+These are single-file, text-only models. The inherited vision components are
+not included because Astrea's visual behavior was not part of the release
+evaluation.
+
+## Run with llama.cpp
+
+Use a current build of
+[llama.cpp](https://github.com/ggml-org/llama.cpp); Qwen3.5 support is recent.
+
+```bash
+llama-cli \
+  -hf Altworld/Astrea-R8-Chat-9B-GGUF:Q5_K_M \
+  -cnv \
+  --reasoning off \
+  --temp 0.8 \
+  --min-p 0.025 \
+  --repeat-penalty 1.08
+```
+
+For an OpenAI-compatible local server:
+
+```bash
+llama-server \
+  -hf Altworld/Astrea-R8-Chat-9B-GGUF:Q5_K_M \
+  --reasoning off \
+  --temp 0.8 \
+  --min-p 0.025 \
+  --repeat-penalty 1.08
+```
+
+Use `--temp 0.2` for factual chat. The model carries its official chat
+template inside the GGUF and does not require a system prompt. Reasoning is
+disabled in the examples because Astrea's release behavior is direct response
+without a visible thinking block.
+
+## Validation
+
+Each file was loaded and generated from with llama.cpp. The checks covered:
+
+- bare greeting with no system prompt;
+- native Astrea/Altworld identity;
+- ordinary factual chat;
+- supportive conversation;
+- creative-writing routing from a plain request with no scene card;
+- multi-turn recall using the embedded chat template.
+
+Q4_K_M, the most aggressive quant here, correctly answered `Good afternoon.`
+as normal chat and produced a coherent story from `Write a short story about a
+dragon who collects spoons.` Q5_K_M correctly recalled a name across turns.
+
+The GGUFs declare the base architecture's 262,144-token context. Actual usable
+context depends on your hardware, llama.cpp build, and runtime settings.
+
+## Conversion details
+
+Converted from the official merged BF16 release with llama.cpp commit
+[`76f46ad`](https://github.com/ggml-org/llama.cpp/commit/76f46ad29d61fd8c1401e8221842934bf62a6064).
+The source checkpoint contains no MTP tensors, so conversion used `--no-mtp`.
+Quantization used llama.cpp's `Q4_K_M`, `Q5_K_M`, `Q6_K`, and `Q8_0` presets.
+
+## About Astrea
+
+Astrea was trained on top of Qwen3.5-9B using multi-round LoRA supervised
+fine-tuning, alternating conversational and narrative rounds and checking each
+round against Altworldbench. See the
+[BF16 model card](https://huggingface.co/Altworld/Astrea-R8-Chat-9B) for
+benchmarks, methodology, examples, limitations, and the evaluation protocol.
+
+Astrea is English-first and can still hallucinate. Verify high-stakes claims
+independently. Engine and quantization differences can affect output, so test
+your own prompts and settings.
