DeepSeek V3 vs GLM-5

DeepSeek V3 (2024) and GLM-5 (2026) are frontier reasoning models from DeepSeek and Zhipu AI. DeepSeek V3 ships a 64k-token context window, while GLM-5 ships a 200k-token context window. On MMLU PRO, GLM-5 leads by 10.1 pts. On pricing, DeepSeek V3 costs $0.10/1M input tokens versus $0.60/1M for the alternative. This comparison covers specs, pricing, API access, capabilities, benchmarks, input and output token costs, and production fit for coding and agent workloads.

DeepSeek V3 is ~500% cheaper at $0.10/1M; pay for GLM-5 only for reasoning depth.

Switch friction

DeepSeek V3 -> GLM-5
  • Provider overlap exists on Fireworks AI, OpenRouter, and Together AI; start route-level A/B tests there.
  • GLM-5 is $1.78/1M tokens higher on cheapest tracked output pricing, so quality gains need to justify the spend.
  • GLM-5 adds Reasoning in local capability data.
GLM-5 -> DeepSeek V3
  • Provider overlap exists on Fireworks AI, OpenRouter, and NVIDIA NIM; start route-level A/B tests there.
  • DeepSeek V3 is $1.78/1M tokens lower on cheapest tracked output pricing before cache, batch, or negotiated discounts.
  • Check replacement coverage for Reasoning before moving production traffic.
