print("Assistant: ", response)

You can see, we are having initial conversation with assistant, where it is not aware of context (check next output also)-

Assistant:  Narendra Modi is the Prime Minister of India, having been in office since May 2014. He is a member of the Bharatiya Janata Party (BJP) and the Rashtriya Swayamsevak Sangh (RSS), a Hindu nationalist volunteer organization. Modi was born on September 17, 1950, in Vadnagar, Gujarat.

Before becoming Prime Minister, he served as the Chief Minister of Gujarat from 2001 to 2014. His tenure as Prime Minister has been marked by significant economic reforms, such as the Goods and Services Tax (GST), the Make in India initiative, and efforts to improve infrastructure and digital connectivity.

Modi's government has also been known for its focus on national security, and he has taken a strong stance on issues concerning terrorism and cross-border relations, especially with Pakistan. He has been a polarizing figure in Indian politics, with both supporters praising his leadership and critics raising concerns about religious tensions and democratic backsliding.

Modi's foreign policy emphasizes strengthening India's global standing and relationships, particularly in the Indo-Pacific region. His leadership style is characterized by a strong central authority and a focus on development and progress.

For the latest developments or specific policies, it is recommended to consult current and authoritative sources.
