DeepSeek R1 vs GPT-5 — Benchmarks, Pricing & Coding Compari…
DeepSeek R1 vs GPT-5: side-by-side benchmarks, pricing, context windows, coding ability and deployment. Pick the right model for your stack.
Overview
DeepSeek R1: DeepSeek R1 is DeepSeek's open-source reasoning model, trained with reinforcement learning to produce chain-of-thought reasoning before answering. Released in January 2025 under the MIT license, it matched or exceeded closed reasoning models on several math and coding benchmarks.
GPT-5: GPT-5 is OpenAI's August 2025 reasoning model for coding, reasoning, and agentic tasks. The API model supports text input and output, image input, configurable reasoning effort, and an immutable gpt-5-2025-08-07 snapshot; OpenAI now classifies it as a previous-generation model.
Context window: DeepSeek R1 accepts up to 128,000 tokens, GPT-5 up to 400,000. Confirm the limit for your specific deployment channel before relying on it.
