Model comparison

GLM-5.3 vs DeepSeek V4

This page compares GLM-5.3 max with the official DeepSeek V4 Pro 0813 max release—not the older preview or the Flash tier. GLM-5.3 leads the independent intelligence index by 7 points and generated about 23% faster. DeepSeek used about 24% fewer output tokens, cost roughly 60% less per evaluated task, supports non-thinking mode, and already publishes MIT-licensed weights. Choose by workload quality, total task economics, and deployment control rather than the family name alone.

How we keep this comparison honest

  • Pin the exact DeepSeek checkpoint: “DeepSeek V4” here means DeepSeek V4 Pro 0813, not V4 Pro Preview, V4 Flash, or V4 Flash 0731.
  • Match max reasoning effort and Artificial Analysis Intelligence Index v4.1.1 for the independent performance table.
  • Keep independent results separate from Z.ai's vendor-reported coding and agent benchmark matrix.
  • Do not blend price bases: DeepSeek's public endpoint list price and Artificial Analysis' tested exact-checkpoint price snapshot are shown as separate evidence.
  • Treat downloadable weights as a deployment option, not an automatic cost win; DeepSeek V4 Pro is a 1.6T-parameter MoE checkpoint with 49B active parameters.

Independent performance and efficiency

Artificial Analysis measured GLM-5.3 max and DeepSeek V4 Pro 0813 max with Intelligence Index v4.1.1. The values below are a dated snapshot of the tested APIs and configurations.

What the independent results mean

  • GLM-5.3 leads the composite intelligence score by 7 points, the strongest quality signal in this matched evaluation.
  • GLM-5.3 generated output about 23% faster on the tested first-party APIs.
  • DeepSeek V4 Pro 0813 cost about 60% less per evaluated task and used about 24% fewer output tokens.
  • The result favors GLM for measured capability and decode speed, and DeepSeek for evaluated task economics and concision.

Matched coding and agent benchmarks reported by Z.ai

Z.ai reports both exact models in the same GLM-5.3 release matrix. These rows use named shared harnesses, but remain vendor-reported evidence and should be reproduced on a private test set.

Pricing needs two separate views

DeepSeek lists deepseek-v4-pro at $0.003625 per million cached-input tokens, $0.435 per million cache-miss input tokens, and $0.87 per million output tokens. Artificial Analysis reports a different tested exact-checkpoint snapshot of $1.32 input and $3.96 output per million tokens for DeepSeek V4 Pro 0813. Provider route, checkpoint mapping, and observation time can explain material differences, so record the returned model version and live billable rates when testing. GLM-5.3 is listed at $0.26 cached input, $1.40 input, and $4.40 output per million tokens.

Self-hosting changes the operational tradeoff

DeepSeek V4 Pro 0813 is already downloadable under MIT and DeepSeek documents vLLM and SGLang deployment, including a 4×GB300 example. The repository is roughly 893 GB and the model has 1.6T total parameters with 49B active, so production serving still requires substantial accelerator memory, interconnect, storage, and operations work. Z.ai had announced but not yet published GLM-5.3 weights at this page's verification point; recheck the official repository before planning GLM self-hosting.

Frequently asked questions

Can I try GLM-5.3 before integrating it?

Use the OneInfer GLM-5.3 launcher to open a prepared prompt in the authenticated playground. Availability is checked against the current model catalog.

How should I treat benchmark claims?

Check the provenance label and harness version. Vendor-reported and independently verified results are deliberately shown as different evidence classes.

Which DeepSeek V4 model is compared here?

DeepSeek V4 Pro 0813 at max reasoning effort. It is the official Pro release that superseded the preview. The results do not describe the smaller V4 Flash or V4 Flash 0731 models.

Which model scored higher independently?

Artificial Analysis Intelligence Index v4.1.1 reports GLM-5.3 max at 60 and DeepSeek V4 Pro 0813 max at 53.

Which model is cheaper?

DeepSeek V4 Pro 0813 had the lower independent cost per task, and DeepSeek's public endpoint list rates are lower than GLM-5.3's. Because the independently observed DeepSeek token rates differ from its public list price, verify the exact route, model version, cache behavior, and invoice rate.

Can both models process images?

No. Both the base GLM-5.3 model and DeepSeek V4 Pro 0813 are text-input models.

Can I self-host DeepSeek V4 Pro 0813?

Yes, its MIT-licensed weights and vLLM/SGLang recipes are published. It is still a very large 1.6T-parameter MoE model, and DeepSeek's example uses a 4×GB300 node, so hardware and operating cost require careful sizing.
