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.

All 7 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 ZAYA1-74B-Preview, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
ZAYA1-74B-Preview is a open weight model with a 256K context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
Official chart snapshot from Zyphra's May 7, 2026 ZAYA1-74B-Preview launch post and matching Hugging Face model card. Zyphra describes this as a pre-RL reasoning-base checkpoint with 74B total and 4B active parameters, not a chat-tuned or RL-post-trained model. BenchLM maps Zyphra's avg@1 chart values to comparable rows and leaves pass@4 rows out of ranking/display until BenchLM has explicit pass@k lanes.
ZAYA1-74B-Preview sits in the ZAYA1 family with ZAYA1-8B, ZAYA1-VL-8B. 7 of 482 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Last updated September 23, 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 ZAYA1-74B-Preview perform overall in AI benchmarks?
ZAYA1-74B-Preview has 7 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 ZAYA1-74B-Preview good for knowledge and understanding?
ZAYA1-74B-Preview has source-displayable benchmark coverage for knowledge and understanding, 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 ZAYA1-74B-Preview good for coding and programming?
ZAYA1-74B-Preview has source-displayable benchmark coverage for coding and programming, 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 ZAYA1-74B-Preview good for mathematics?
ZAYA1-74B-Preview has source-displayable benchmark coverage for mathematics, 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 ZAYA1-74B-Preview good for agentic tool use and computer tasks?
ZAYA1-74B-Preview has source-displayable benchmark coverage for agentic tool use and computer tasks, 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 ZAYA1-74B-Preview open source?
ZAYA1-74B-Preview is an open-weight model from Zyphra. 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 ZAYA1-74B-Preview?
ZAYA1-74B-Preview belongs to the ZAYA1 family. Related tracked variants include ZAYA1-8B, ZAYA1-VL-8B. 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 ZAYA1-74B-Preview have full benchmark coverage on BenchLM?
No. ZAYA1-74B-Preview currently has 7 source-displayable rows across 482 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 ZAYA1-74B-Preview?
ZAYA1-74B-Preview has a reported context window of 256K 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.
