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.

DeepSeek V3.1 (Reasoning) ranks #144 of 224 on the public leaderboard with a score of 39.18/100. It does not yet have enough sourced coverage for a verified position.

DeepSeek V3.1 (Reasoning) is a open weight model with a 128K context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.

DeepSeek V3.1 (Reasoning) sits in the DeepSeek V3.1 family with DeepSeek V3.1. 6 of 681 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.

Its strongest eligible category is Knowledge at #116. particularly effective for knowledge-intensive tasks like research, analysis, and factual Q&A.

Last updated October 17, 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.

Questions

How does DeepSeek V3.1 (Reasoning) perform overall in AI benchmarks?

DeepSeek V3.1 (Reasoning) ranks #144 out of 224 models on the public BenchAlign leaderboard, with a score of 39.18/100. Its evidence status is Estimated, and this profile shows 6 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.

Is DeepSeek V3.1 (Reasoning) good for knowledge and understanding?

DeepSeek V3.1 (Reasoning) ranks #116 out of 184 eligible models for knowledge and understanding, with a public category score of 40.7/100. 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 DeepSeek V3.1 (Reasoning) good for coding and programming?

DeepSeek V3.1 (Reasoning) 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 DeepSeek V3.1 (Reasoning) good for mathematics?

DeepSeek V3.1 (Reasoning) 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 DeepSeek V3.1 (Reasoning) open source?

DeepSeek V3.1 (Reasoning) is an open-weight model from DeepSeek. 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 DeepSeek V3.1 (Reasoning)?

DeepSeek V3.1 (Reasoning) belongs to the DeepSeek V3.1 family. Related tracked variants include DeepSeek V3.1. 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 DeepSeek V3.1 (Reasoning) have full benchmark coverage on BenchLM?

No. DeepSeek V3.1 (Reasoning) currently has 17 source-displayable rows across 681 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 DeepSeek V3.1 (Reasoning)?

DeepSeek V3.1 (Reasoning) has a reported context window of 128K 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.
