DeepSeek V3.2 vs GLM-5.1

Updated August 7, 2026. Public scores include evidence status and uncertainty. They are not guarantees for a specific workload.

DeepSeek V3.2

DeepSeek

54.4/100

Supported · Public rank #91

90% interval 37.8–71.1

GLM-5.1

Z.AI

66.9/100

Supported · Public rank #22

90% interval 57.1–76.7

GLM-5.1 has the higher public score estimate, 66.9 versus 54.44, but the 90% score intervals overlap. Treat that as a lead, not a settled winner.

5 results are shared. Category rows based on different benchmark sets are marked directional and do not name a winner.

Which one for your work

Recommendations appear only when a shared evidence basis or an explicit operating constraint supports the call. Secondary and unsupported use cases stay disclosed below the initial list.

  • Long documents

    Prompts that approach the documented context limit

    GLM-5.1

    GLM-5.1 has the larger documented context window.

    Confidence: documented

  • Chat turn cost

    1K fresh input + 500 output tokens

    DeepSeek V3.2

    DeepSeek V3.2 has the lower estimated token cost for this stated workload. Costs use the listed standard API rates.

  • Repository review cost

    50K fresh input + 3K output tokens

    DeepSeek V3.2

    DeepSeek V3.2 has the lower estimated token cost for this stated workload. Costs use the listed standard API rates.

    Confidence: listed-rates

  • Coding work

    Code generation, repair, and software-engineering tasks

    Not enough matched evidence

    The category averages use different weighted benchmark sets, so they are directional rather than like-for-like.

    Confidence: limited

  • Agentic work

    Tool use, computer use, and multi-step task completion

    Not enough matched evidence

    No shared weighted benchmark basis supports a winner.

    Confidence: limited

  • Cache-heavy agent loop cost

    200K cached + 20K fresh input + 10K output tokens

    Not enough matched evidence

    The page does not recommend a cost winner because at least one model cannot fit the stated workload in one request. DeepSeek V3.2 does not fit this workload in one request. GLM-5.1 does not fit this workload in one request. GLM-5.1 has no published cached-input rate, so cached tokens use its listed input rate.

    Confidence: rate-fallback

What is actually comparable

Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.

Shape of the matched evidence

Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.

Too few matched category axes support a radar. The ruled list below shows only shared benchmark results; positions use each benchmark’s normalized display scale when available.

What each workload costs

Three fixed token mixes turn per-token rates into comparable decisions. Each scenario states context fit and whether cached input had to fall back to the published list-input rate.

Cached input priced at the published list-input rate

DeepSeek V3.2 does not fit this workload in one request. GLM-5.1 does not fit this workload in one request. GLM-5.1 has no published cached-input rate, so cached tokens use its listed input rate.

Specification differences

Sourced differences are shown directly. Missing facts stay explicit instead of being inferred from a model name or family.

Deployment change
The models list different providers, so authentication, endpoint behavior, limits, and feature support may change.
Quality signal
GLM-5.1 has the higher public score estimate, 66.9 versus 54.44, but the 90% score intervals overlap.
Workload cost
Repository review: $0.01526 vs $0.0832. Cache-heavy agent loop: $0.0154 vs $0.352.
Context tradeoff
GLM-5.1 has the larger documented window (203K).

Run the same representative tasks against both endpoints before changing production traffic.

Frequently asked questions

Which is better, DeepSeek V3.2 or GLM-5.1?

GLM-5.1 has the higher public score estimate, 66.9 versus 54.44, but the 90% score intervals overlap. The higher estimate is not a decisive winner because the uncertainty ranges overlap.

Which is better for coding, DeepSeek V3.2 or GLM-5.1?

The current coding averages use different weighted benchmark sets, so BenchLM does not name a winner from them. Read the shared benchmark rows directly and test the models on the same task set.

Which is better for agentic tasks, DeepSeek V3.2 or GLM-5.1?

The published evidence does not provide a shared weighted agentic tasks basis for both models, so BenchLM does not name a agentic tasks winner.

Which costs less, DeepSeek V3.2 or GLM-5.1?

For the stated presets, chat costs $0.00049 on DeepSeek V3.2 and $0.0036 on GLM-5.1; repository review costs $0.01526 and $0.0832; the cache-heavy agent loop costs $0.0154 and $0.352. DeepSeek V3.2 does not fit this workload in one request. GLM-5.1 does not fit this workload in one request. GLM-5.1 has no published cached-input rate, so cached tokens use its listed input rate.

Which has the larger context window, DeepSeek V3.2 or GLM-5.1?

GLM-5.1 has the larger documented context window: 203K, compared with 128K.
