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 parametersLineage
The sequence follows explicit supersedes links. A successor's displayed score stays at least 0.1 points above its predecessor; raw benchmark rows do not move. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

Reasoning
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 DeepSeek V3.1 (Reasoning), but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.
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. The profile has no source-displayable benchmark row yet.
Frequently asked questions
How does DeepSeek V3.1 (Reasoning) perform overall in AI benchmarks?
DeepSeek V3.1 (Reasoning) does not have any source-displayable benchmark rows yet, so this profile does not assign a public score or rank. Documented specifications remain visible, while score-led charts and claims stay unavailable until a published evaluation can be attached to the exact model.
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 12 source-displayable rows across 416 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.
