Ornith-1.5-9B
Ornith·
Overview
Smallest member of the Ornith-1.5 family: a dense 9B under MIT with a 262K native context and a quantised mobile build for iPhone and Android. GGUF checkpoints range from about 2.8 GB to 17.9 GB, so an 8 GB card runs a Q4/Q5 build and 24 GB runs BF16; on Apple Silicon the same builds run through Metal via MLX. Vendor-reported at launch: Terminal-Bench 2.1 47.0 (Harbor/Terminus-2, 128K context) and SWE-bench Verified 70.6 (OpenHands harness, 256K context). Ornith's size-comparison claims are size-adjusted — the 35B MoE of the same family still scores higher on both figures.
Post-trained from Qwen3.5 (Alibaba, family-level attribution). Ornith-1.0 was built on Qwen3.5 and Gemma 4 with continued pretraining, mid-training and post-training. Third-party reporting maps the 1.0 9B onto Qwen3.5 9B and puts the Gemma 4 lineage in the 31B, which Ornith-1.5 does not continue; Ornith publishes no per-variant mapping of its own, so the lineage is recorded at family level.
Capabilities and innovations
Benchmarks
| Benchmark | Score | Source |
|---|---|---|
| SWE-bench Verified | 70.6% | vendor SWE-bench Verified 70.6 under the OpenHands harness (temp 1.0, top_p 0.95, 256K context). Era-1 benchmark, recorded only because Ornith reports it. Same transcription caveat. |
| Terminal-Bench 2.x | 47% | vendor Terminal-Bench 2.1 47.0 (Harbor/Terminus-2, 128K context) from the model card. Card not fetchable from this environment; value taken from consistent secondary transcriptions and not independently reproduced. |
- SWE-bench Pro: independent evaluation pending — Reported in the launch table under the OpenHands harness but not transcribed in accessible coverage.
- GPQA Diamond: not reported by the vendor — Coding- and agent-focused launch table only.
- Humanity’s Last Exam (no tools): not reported by the vendor — Coding- and agent-focused launch table only.
- MMLU-Pro: not reported by the vendor — Coding- and agent-focused launch table only.
