The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
Ornith-1.5-35B-A3B ranks #156 of 212 on the public leaderboard with a score of 32.61/100. It does not yet have enough sourced coverage for a verified position.
Ornith-1.5-35B-A3B is a open weight model with a 262K context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
Ornith publishes the MIT-licensed 35B MoE, with 3B active parameters, for self-hosted use. Its official Hugging Face configuration specifies a 262,144-token context window; no first-party hosted API or token rate is published for this exact model.
Official exact-value snapshot from Ornith's August 2026 Ornith-1.5 launch page. BenchLM maps the directly comparable provider-reported rows, including the versioned Terminal-Bench 2.1, DeepSWE, and Terminal-Bench 3.0 results as distinct display evidence; the source says all Ornith-1.5 results are averaged over five runs. SWE Atlas QnA and Terminal-Bench Claude Code remain outside the current schema. The family remains unranked while independent benchmark-native coverage is unavailable.
Ornith-1.5-35B-A3B sits in the Ornith 1.5 family with Ornith-1.5-397B, Ornith-1.5-9B. Its explicit predecessor is Ornith-1.0-35B. 18 of 645 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Its strongest eligible category is Agentic at #95, while its lowest eligible position is Knowledge at #119. particularly useful for coding agents, browser research, and computer-use workflows.
Last updated October 2, 2026. Runtime fields remain blank until a sourced snapshot exists.
Deployment options
Self-host and provider-specific paths stay separate from benchmark evidence so operating constraints are visible before a score becomes the whole decision.
Published weights are available, but BenchLM does not yet have a sourced parameter and VRAM profile for this exact model. Hardware cost estimates stay unavailable until that sizing record is complete.

How does Ornith-1.5-35B-A3B perform overall in AI benchmarks?
Ornith-1.5-35B-A3B ranks #156 out of 212 models on the public BenchAlign leaderboard, with a score of 32.61/100. Its evidence status is Estimated, and this profile shows 18 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.
Is Ornith-1.5-35B-A3B good for knowledge and understanding?
Ornith-1.5-35B-A3B ranks #119 out of 171 eligible models for knowledge and understanding, with a public category score of 34.5/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Ornith-1.5-35B-A3B good for coding and programming?
Ornith-1.5-35B-A3B ranks #110 out of 144 eligible models for coding and programming, with a public category score of 24/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Ornith-1.5-35B-A3B good for agentic tool use and computer tasks?
Ornith-1.5-35B-A3B ranks #95 out of 119 eligible models for agentic tool use and computer tasks, with a public category score of 23.5/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Ornith-1.5-35B-A3B open source?
Ornith-1.5-35B-A3B is an open-weight model from Ornith AI. Its weights can be downloaded for local or hosted deployment, subject to the published license. Open weight does not automatically mean open source: training data and training code may remain private, and commercial restrictions can still apply.
Which sibling models are related to Ornith-1.5-35B-A3B?
Ornith-1.5-35B-A3B belongs to the Ornith 1.5 family. Related tracked variants include Ornith-1.5-397B, Ornith-1.5-9B. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does Ornith-1.5-35B-A3B have full benchmark coverage on BenchLM?
No. Ornith-1.5-35B-A3B currently has 18 source-displayable rows across 645 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of Ornith-1.5-35B-A3B?
Ornith-1.5-35B-A3B has a documented context window of 262K. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
