In this world, it is difficult to be a good person. DeepSeek is the world's first company to publicly disclose CoT, or Chain of Thought, for RL. Before that, only OAI clearly knew how to apply CoT-RL, but OAI treated it as a trade secret and did not disclose the reasoning. There is no evidence that Company A applied CoT-RL prior to this. However, today Company A accuses DS of plagiarizing its reasoning chain. There is no greater deception than this.
