DeepSeek R1 vs GLM-5

DeepSeek R1 (2025) and GLM-5 (2026) are frontier-tier reasoning models from DeepSeek and Zhipu AI. DeepSeek R1 ships a 128k-token context window, while GLM-5 ships a 200k-token context window. On SWE-bench Verified, GLM-5 leads by 28.6 pts. On pricing, DeepSeek R1 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 R1 is ~500% cheaper at $0.10/1M; pay for GLM-5 only for long-context analysis.

Switch friction

DeepSeek R1 -> 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.
  • Check replacement coverage for Code execution before moving production traffic.
  • GLM-5 adds JSON / Tool use in local capability data.
