DeepSeek R1 vs DeepSeek V3

DeepSeek R1 (2025) and DeepSeek V3 (2024) are frontier reasoning models from DeepSeek. DeepSeek R1 ships a 128k-token context window, while DeepSeek V3 ships a 64k-token context window. On HumanEval, DeepSeek R1 leads by 4.4 pts. On pricing, both list $0.10/1M input and $0.30/1M output tokens on the cheapest tracked route. This comparison covers specs, pricing, API access, capabilities, benchmarks, input and output token costs, and production fit for coding and agent workloads.

Pick DeepSeek R1 for coding; token pricing is tied, so keep DeepSeek V3 only for already-validated prompts or route constraints.

Switch friction

DeepSeek R1 -> DeepSeek V3
  • Provider overlap exists on DeepInfra, Fireworks AI, and DeepSeek Platform; start route-level A/B tests there.
  • Cheapest tracked output pricing is tied, so migration risk shifts to quality, latency, and provider packaging.
  • Check replacement coverage for Reasoning and Code execution before moving production traffic.
  • DeepSeek V3 adds JSON / Tool use in local capability data.
