All 12 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 Perplexity Decider v1 27B, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
Perplexity Decider v1 27B is a open weight model with a 262144 tokens context window. No explicit reasoning mode is documented in this profile.
Perplexity released this Qwen3.8-27B fine-tune under Apache 2.0 on October 1, 2026. The published 11-task decision panel reports 85.71% accuracy over 7,210 rows, measured through the Perplexity API. Those provider-reported results have separate display-only keys and do not establish a general model rank. The released config specifies 262,144 positions; API requests must stay below 262,144 input tokens across state, images, and questions. The model card describes approximately 49 GiB of weights plus working memory for local CUDA inference.
12 of 645 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Last updated October 1, 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 Perplexity Decider v1 27B perform overall in AI benchmarks?
Perplexity Decider v1 27B has 12 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 Perplexity Decider v1 27B open source?
Perplexity Decider v1 27B is an open-weight model from Perplexity. 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.
Does Perplexity Decider v1 27B have full benchmark coverage on BenchLM?
No. Perplexity Decider v1 27B currently has 12 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 Perplexity Decider v1 27B?
Perplexity Decider v1 27B has a documented context window of 262144 tokens. 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.
