DeepSeek V3.2 vs GLM 5

DeepSeek · China  |  Z.ai · China · Updated June 2026

Quick verdict

Pick DeepSeek V3.2 for long-context efficiency via deepseek sparse attention (dsa) or agentic tool-use with thinking integrated into tool calls (thinking/non-thinking modes). Pick GLM 5 for agentic planning and long-horizon coding workflows or complex systems design and backend reasoning. On a tight budget at scale, DeepSeek V3.2 is the value pick.

DeepSeek V3.2 (DeepSeek) and GLM 5 (Z.ai) are two of the models people most often weigh against each other in 2026. DeepSeek V3.2 is a cost-efficient, open-weight (MIT) 685B-parameter MoE model whose DeepSeek Sparse Attention delivers GPT-5-comparable reasoning with far cheaper long-context inference. GLM 5 is z.ai's flagship open-weight (MIT) MoE foundation model, engineered for complex systems design and long-horizon agentic coding. They diverge most on price, context window and coding benchmarks — each quantified below from the models' real specs.

Who wins what

Long-context efficiency via DeepSeek Sparse Attention (DSA)

DeepSeek V3.2

GLM 5 is comparatively weak here — 200K context trails 1M-context rivals

Agentic tool-use with thinking integrated into tool calls (thinking/non-thinking modes)

DeepSeek V3.2

A cost-efficient, open-weight (MIT) 685B-parameter MoE model whose DeepSeek Sparse Attention delivers GPT-5-comparable reasoning with far cheaper long-context inference — and it runs cheaper at $0.28/$0.42 per 1M tokens.

Elite competition math and reasoning (AIME 2025 93.1, Codeforces 2386)

DeepSeek V3.2

DeepSeek V3.2 lists elite competition math and reasoning (AIME 2025 93.1, Codeforces 2386) among its strengths; GLM 5 does not.

Agentic planning and long-horizon coding workflows

GLM 5

It scores 77.8% on SWE-Bench Verified against DeepSeek V3.2's 73.1% — a 4.7-point edge on real repository work.

Complex systems design and backend reasoning

GLM 5

Z.ai's flagship open-weight (MIT) MoE foundation model, engineered for complex systems design and long-horizon agentic coding — and it leads SWE-Bench Verified 77.8% to 73.1%.

Iterative self-correction on autonomous tasks

GLM 5

Z.ai's flagship open-weight (MIT) MoE foundation model, engineered for complex systems design and long-horizon agentic coding — and it carries the larger 200K context.

Lowest cost at scale

DeepSeek V3.2

At $0.28/$0.42 per 1M tokens, it is the cheaper of the two — the gap dominates the bill on high-volume workloads.

Largest single-prompt input

GLM 5

Its 200K window is about 1.5× larger than DeepSeek V3.2's 131K, fitting roughly 300 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

DeepSeek V3.2

At $0.28/$0.42 per 1M tokens it undercuts GLM 5, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

GLM 5

Larger 200K window fits more in one prompt.

Anyone whose priority is long-context efficiency via deepseek sparse attention (dsa)

DeepSeek V3.2

It is specifically built for that.

Anyone whose priority is agentic planning and long-horizon coding workflows

GLM 5

That is its strongest area.

DeepSeek V3.2: where it fits

A cost-efficient, open-weight (MIT) 685B-parameter MoE model whose DeepSeek Sparse Attention delivers GPT-5-comparable reasoning with far cheaper long-context inference. Released December 1, 2025 by DeepSeek, it is built for long-context efficiency via DeepSeek Sparse Attention (DSA), agentic tool-use with thinking integrated into tool calls (thinking/non-thinking modes), elite competition math and reasoning (AIME 2025 93.1, Codeforces 2386), and low-cost, open-weight (MIT) self-hosting.

Its trade-offs are real: text-only — no image, audio, or video input, and sWE-Bench Verified (73.1) trails the top closed coding models (Claude 4.5 Sonnet 77.2, Gemini 3 Pro 76.2). At $0.28 in / $0.42 out per million tokens, it sits in the budget price band.

GLM 5: where it fits

Z.ai's flagship open-weight (MIT) MoE foundation model, engineered for complex systems design and long-horizon agentic coding. Released February 11, 2026 by Z.ai, it is built for agentic planning and long-horizon coding workflows, complex systems design and backend reasoning, iterative self-correction on autonomous tasks, and open weights under the permissive MIT license.

Its trade-offs: 200K context trails 1M-context rivals, and quickly superseded by GLM-5.1 and GLM-5.2. At $1 in / $3.2 out per million tokens, it sits in the budget price band.

The bottom line for this matchup

DeepSeek V3.2 and GLM 5 overlap enough that the right pick depends on your specific job. DeepSeek V3.2 costs less per token; GLM 5 holds the larger context; and each leads in its own area — DeepSeek V3.2 for long-context efficiency via deepseek sparse attention (dsa), GLM 5 for agentic planning and long-horizon coding workflows. Rather than crowning one, run the same hard task through both once and let the results decide.
