The source confirms that Lilian Weng works at OpenAI (she refers to 'my team at OpenAI'), but the excerpt does not explicitly state her title as 'VP of Research' or provide a start date of 2018. The blog itself started in 2017, which is consistent with her being at OpenAI by 2018, but this is not directly confirmed. The role and exact start date cannot be verified from this source material alone.
