OpenAI is providing access to its ChatGPT product to US federal agencies at a nominal cost of $1 a year as part of a push to get its AI chatbot more widely adopted.

In a major shift, the company is “open sourcing” two A.I. systems, freely sharing the technology with outside researchers and businesses.

OpenAI says it has tweaked ChatGPT to ensure the model responds appropriately when a user shows distress.
