+
+   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

+      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.

+      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.

+# Astrea R8 Chat 9B — Q8_0 GGUF
+
+This is an unofficial community Q8_0 GGUF conversion of
+[Altworld/Astrea-R8-Chat-9B](https://huggingface.co/Altworld/Astrea-R8-Chat-9B)
+for llama.cpp, with an explicit non-reasoning chat template.
+
+## File
+
+| File | Quantization | Size |
+|---|---:|---:|
+| `Astrea-R8-Chat-9B-Q8_0.gguf` | Q8_0 | 9,527,501,280 bytes (8.87 GiB) |
+
+## Embedded non-reasoning template
+
+The GGUF contains a hard non-reasoning Jinja template in
+`tokenizer.chat_template`; no external template file is required.
+
+Astrea's optional thinking mode was not reliable in local llama.cpp testing:
+simple prompts could consume hundreds of tokens before emitting `</think>`, and often did not end reasoning at all, and simply responded as if reasoning was not enabled.
+The bundled template therefore always places a closed, empty thinking block in
+the prompt and does not expose an `enable_thinking` template variable. It also
+omits hidden reasoning when replaying assistant messages into conversation
+history. A standalone copy is included as `chat_template.jinja` for inspection.
+
+## llama.cpp
+
+```powershell
+llama-server.exe `
+  --model Astrea-R8-Chat-9B-Q8_0.gguf `
+  --jinja `
+  --reasoning off `
+  --reasoning-format none `
+  --ctx-size 32768 `
+  --n-gpu-layers all `
+  --temp 0.8 `
+  --top-p 1.0 `
+  --top-k 0 `
+  --min-p 0.025 `
+  --repeat-penalty 1.08
+```
+
+The model metadata advertises a 262,144-token context window. Choose a context
+size appropriate for your available VRAM/RAM. The command above starts at a
+more conservative 32,768 tokens. I was able to easily run a much more ambitous setup with `-ngl all --fit off -c 147456 -np 4 --kv-unified` on a 16GB VRAM card (5070 Ti).
+
+## Conversion notes
+
+1. The original safetensors were converted to BF16 GGUF with llama.cpp's
+   `convert_hf_to_gguf.py` using `--no-mtp`. The downloaded checkpoint did not
+   contain the extra MTP-layer tensors declared by its configuration.
+2. BF16 was quantized with `llama-quantize` using `Q8_0`.
+3. llama.cpp's `gguf_new_metadata.py` embedded the hard non-reasoning template;
+   this metadata-only copy did not requantize tensors.
+
+The tensor-only SHA-256 reported by `llama-gguf-hash` was identical before and
+after the metadata rewrite:
+
+```text
+20d213a0c5ee663ef6d02ffcff8d0b28cbff18b559c67aca5250cd5e6a22d624
+```
+
+The final whole-file checksums are in `SHA256SUMS`.
+
+## Validation
+
+The final GGUF was loaded directly by `llama-server` without
+`--chat-template-file`. Its exposed template matched the bundled standalone
+Jinja, and a request that explicitly supplied `enable_thinking=true` still
+returned normal content with no `reasoning_content`.
+
+## License and attribution
+
+The source model is released under Apache-2.0. See `LICENSE` and `NOTICE`, and
+refer to the [source model card](https://huggingface.co/Altworld/Astrea-R8-Chat-9B)
+for its intended use, evaluation results, and limitations.
