Ornith-1.5-9B-GGUF

Model Card for aquaduck/Ornith-1.5-9B-GGUF

Pinned Q4_K_M GGUF of Ornith-1.5-9B (ornith-ai/ornith-1.5-9b), plus midpoint layer shards for staged / multi-node loading (Aquaduck Arc layer-package-v1). The shard files are not a new quantization. They are contiguous midpoint packages cut from the full Q4_K_M GGUF in this repo.

Model Details

Model Description

• Hosted by: Aquaduck (hosting and layer packaging only; base model by ornith-ai; GGUF quant by Unsloth / llama.cpp ecosystem)
• Shared by: Aquaduck AI
• Model type: Causal language model (Ornith-1.5-9B), GGUF Q4_K_M
• Language(s): Multilingual (same as base)
• License: other (inherits from ornith-ai/ornith-1.5-9b)
• Finetuned from model: N/A — not a fine-tune
• Derived from: ornith-ai/Ornith-1.5-9B-GGUF ← ornith-ai/ornith-1.5-9b

Model Sources

• Base model card: https://huggingface.co/ornith-ai/ornith-1.5-9b
• Quantized GGUF source: https://huggingface.co/ornith-ai/Ornith-1.5-9B-GGUF

Files

• Total layers: 32
• Valid split boundaries: 16 Filenames use exclusive end indices (layers-{start}-{endExclusive}).

Uses

Direct Use

• Full Ornith-1.5-9B-Q4_K_M.gguf: standard single-file Q4_K_M GGUF (llama.cpp-compatible). Use this for single-node / local runs.
• *-layers-*.gguf: Aquaduck / Arc staged loading only. These are not drop-in complete models for stock llama.cpp. Use the base model’s chat template (including thinking / instruct modes as documented on the base model card); other formats will not work correctly.

Out-of-Scope Use

• Expecting any one shard to run as a complete model
• Treating this repo as a new training run or re-quant
• Uses prohibited by the other license or the base model’s model card guidance

Bias, Risks, and Limitations

Same capabilities, biases, and risks as ornith-ai/ornith-1.5-9b. Q4_K_M quantization can degrade quality vs. the original higher-precision releases. Layer sharding does not change weights beyond packaging.

Recommendations

Follow the base model’s docs for chat template, thinking vs instruct modes, and sampling. Prefer Ornith-1.5-9B-Q4_K_M.gguf in this repo when you do not need staged loading.

How to Get Started

These files are meant to be loaded automatically by the Aquaduck desktop app.

1. Download the Aquaduck desktop app and sign in.
2. Devices connected to the internet will receive a model assignment from the model catalog (ornith-ai/ornith-1.5-9b).
3. Download the model from the Home view. The app will:
   • download only the assigned file from this repo (full Ornith-1.5-9B-Q4_K_M.gguf or one midpoint half)
   • keep that stage ready for serving You do not need to pick files by hand, but you may for local serving. Assignment and download are driven by model catalog metadata. The full Ornith-1.5-9B-Q4_K_M.gguf is a standard Q4_K_M GGUF. The *-layers-*.gguf files are not.

Training Details

No training. Weights come from ornith-ai; Q4_K_M GGUF from ornith-ai/Ornith-1.5-9B-GGUF; this repo hosts that GGUF and (when split) packages it into midpoint layer shards.

Evaluation

No separate evals for the hosted GGUF or shards. See ornith-ai/ornith-1.5-9b.
