Yes — with 4.5 GB to spare
Ornith 1.5 9B at Q4_K_M fits your Radeon RX 7700 XT entirely on the GPU at 8K context, at an estimated 49 tokens per second. Past 150K the KV cache pushes it over — quantise the cache to q8_0, or step down a quantisation, to go longer.
The small Ornith: a coding-agent reasoning build on the Qwen3.5 9B architecture. Same VRAM as its base, thinks before every answer.
The VRAM budget
Quantisation ladder
| Quant | Weights | Total @ 8K | Max context | Tok/s | Quality | Fit |
|---|---|---|---|---|---|---|
| F16 | 17.5 GB | 18.4 GB | — | ~4.0 | Reference | 7.8 GB over |
| Q8_0 | 9.3 GB | 10.2 GB | 22K | 28 | −0.1% ppl | Long context |
| Q6_K | 7.2 GB | 8.0 GB | 90K | 36 | −0.4% ppl | Long context |
| Q5_K_M | 6.2 GB | 7.1 GB | 121K | 42 | −0.8% ppl | Long context |
| Q4_K_M | 5.3 GB | 6.1 GB | 150K | 49 | −1.9% ppl | Recommended |
| Q3_K_M | 4.3 GB | 5.1 GB | 182K | 61 | −5.4% ppl | Long context |
| Q2_K | 3.7 GB | 4.5 GB | 202K | 71 | −15% ppl | Long context |
Quality is the published perplexity delta against f16 weights. Max context assumes an f16 KV cache; q8_0 roughly doubles it. Only 8 of its 32 blocks keep a per-token KV cache; the rest are linear-attention, Mamba or convolution blocks with a fixed-size state.
How to run it
$ ollama pull ornith-1.5:9b $ OLLAMA_CONTEXT_LENGTH=8192 \ ollama run ornith-1.5:9b
The default. One binary, a model registry, an OpenAI-compatible port. More on Ollama.
