Is Deepseek Using OpenAI? API Response Suggests So

Discussion
1

I used OpenRouter AI API with the deepseek-chat model, but when I asked “Who are you?” it responded, “I’m an AI language model created by OpenAI, called ChatGPT.”
Does this mean Deepseek is actually using OpenAI? Or is OpenRouter misleading us? Has anyone else experienced this?

Deepseek was highly trained on synthetic data of openAI. Thats what many people are guessing. Sam cant blame DeepSeek for that because if he say this Investors could argue that OpenAI dont need that much money to make a better model.

It could mean anything, including it is hallucinating. Most models are not self aware, and have no internal “identity” to reference in their training data.

But accusations are flying that DeepSeek is a distilled version of one of the OpenAI models.

Model distillation is very common these days. DeepSeek, in their paper, starts with a pure reasoning model, that reasons in multiple languages, and is incoherent.

Then they flow coherent model responses through the model to train it to speak coherently. So reasoning first, then language. Quite interesting.

OpenAI claims that DS-R1 was trained on OpenAI output. So yes its known that it outputs that. If someone is not aware of this it may confuse you.

There is a lot of confusion about distillation as sometimes you do not use DeepSeek R1 but a further ‘distilled’ version that has been trained for reasoning with DeepSeek R1 output into an LLAMA model. (if the model is 687B parameters or so then its not actual DeepSeek R1 , any model of 70B or smaller is actually the LLAMA distilled version.

DeepSeek R1 was primarily trained using reinforcement learning techniques, focusing on enhancing reasoning capabilities without a prior step of supervised fine-tuning. This method allowed it to achieve reasoning abilities comparable to leading models like OpenAI’s o1. Language training was integrated subsequently to refine its language processing skills
