Category score record
Scores and ranks appear only where published evidence can be displayed. The table keeps the score, weight, cohort, and evidence state together.

Coverage detailsHow much of this is verified
Coverage is split by category so a strong number never hides a thin evidence base. Verified means the row is tied to a published source; provisional rows remain visible but separate.

Benchmark ledger
Reasoning opens by default. The marker compares each value with the best source-verified result in the catalog; provisional leaders do not set the reference. Expand the remaining categories for every published row.

All 2 rowsLineage
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.
We track 1-bit Bonsai 8B, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
1-bit Bonsai 8B is a open weight model with a 64K context window. No explicit reasoning mode is documented in this profile.
Official exact-value snapshot from Prism ML's March 31, 2026 whitepaper and matching Bonsai-8B model card. BenchLM maps only directly comparable fields from the paper: GPQA Diamond, MuSR, IFEval, and MATH-500. MMLU-Redux, GSM8K, HumanEval+, MBPP+, BFCLv3, and IFBench remain out-of-schema or non-equivalent to current core ranking keys.
1-bit Bonsai 8B sits in the 1-bit Bonsai family with 1-bit Bonsai 27B, 1-bit Bonsai 1.7B, 1-bit Bonsai 4B. 2 of 782 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Last updated October 29, 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.
Estimate VRAM from known parametersQuestions
How does 1-bit Bonsai 8B perform overall in AI benchmarks?
1-bit Bonsai 8B has 2 source-displayable benchmark rows, but it does not qualify for a public overall rank. The available rows remain visible by category without being converted into a site-wide score. Missing evidence stays blank instead of being estimated from an earlier model.
Is 1-bit Bonsai 8B good for reasoning and logic?
1-bit Bonsai 8B has source-displayable benchmark coverage for reasoning and logic, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Is 1-bit Bonsai 8B good for instruction following?
1-bit Bonsai 8B has source-displayable benchmark coverage for instruction following, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Is 1-bit Bonsai 8B open source?
1-bit Bonsai 8B is an open-weight model from Prism ML. 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 1-bit Bonsai 8B?
1-bit Bonsai 8B belongs to the 1-bit Bonsai family. Related tracked variants include 1-bit Bonsai 27B, 1-bit Bonsai 1.7B, 1-bit Bonsai 4B. 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 1-bit Bonsai 8B have full benchmark coverage on BenchLM?
No. 1-bit Bonsai 8B currently has 2 source-displayable rows. 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 1-bit Bonsai 8B?
1-bit Bonsai 8B has a reported context window of 64K in the exact-model catalog record. The value stays visible, but the profile marks its source link as unavailable instead of presenting it as directly documented. Maximum output length remains separate because providers often publish a different limit.
