Coverage details

How 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.

What it costs to get this score

Published API price against the public score. The x-axis uses a log scale; the dashed path marks models that are not beaten by a cheaper, higher-scoring option. Price uses average of published input and output rates.

Lineage

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.

Qwen3.5 Plus ranks #87 of 201 on the public leaderboard with a score of 48.77/100. It does not yet have enough sourced coverage for a verified position.

Qwen3.5 Plus is a proprietary model with a 1M context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.

Official first-party benchmark snapshot from the Qwen Agent DeepPlanning v1.1 leaderboard. BenchLM now tracks the published DeepPlanning score for the hosted Qwen3.5 Plus API tier while broader benchmark coverage remains sparse.

4 of 486 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.

Last updated September 28, 2026. Runtime fields remain blank until a sourced snapshot exists.

Questions

How does Qwen3.5 Plus perform overall in AI benchmarks?

Qwen3.5 Plus ranks #87 out of 201 models on the public BenchAlign leaderboard, with a score of 48.77/100. Its evidence status is Estimated, and this profile shows 4 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.

Is Qwen3.5 Plus good for coding and programming?

Qwen3.5 Plus 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 Qwen3.5 Plus good for mathematics?

Qwen3.5 Plus 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 Qwen3.5 Plus good for agentic tool use and computer tasks?

Qwen3.5 Plus 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.

Does Qwen3.5 Plus have full benchmark coverage on BenchLM?

No. Qwen3.5 Plus currently has 4 source-displayable rows across 486 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 Qwen3.5 Plus?

Qwen3.5 Plus has a reported context window of 1M 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.
