Posts on X — and TechCrunch’s own tests — show that DeepSeek V3 identifies itself as ChatGPT, OpenAI’s AI-powered chatbot platform. Asked to elaborate, DeepSeek V3 insists it is a version of OpenAI’s GPT-4 model released in 2023.

DeepSeek put its algorithm to the test by comparing it with three other open-source LLMs: the previous-generation DeepSeek-V2, Llama 3.1 405B and Qwen2.5 72B. DeepSeek-V3 achieved higher scores across all nine of the coding and math benchmarks that were used in the evaluation. It also proved better at a range of text processing tasks.
