At one time the whole island was covered with forests, and there are still many cedar (Cedrela odorata), chechem (Metopium brownei), mahogany (Swietenia mahagoni), and other valuable trees. Cuba makes maritime claims that include a territorial sea of 12 nautical miles (22.2 km; 13.8 mi) and an exclusive economic zone of 350,751 km2 (135,426 mi2) with 200 nautical miles (370.4 km; 230.2 mi). The largest natural water mirror is Laguna de Leche at 67.2 km2 (25.9 sq mi), while the man-made Zaza Reservoir, at 113.5 km2 (43.8 sq mi), is the largest inland water surface by area in the country. Its main island is the 17th-largest island in the world by land area. The largest island outside the main island is the Isla de la Juventud is (Isle of Youth) in the southwest, with an area of 2,204 km2 (851 sq mi).

Cuba has historically—before and during communist rule—performed better than other countries in Latin America and the Caribbean on several socioeconomic indicators, such as literacy, infant mortality, and life expectancy. Raúl retired as president of the Council of State in 2018, and Miguel Díaz-Canel was elected president by the National Assembly following parliamentary elections. Following the dissolution of the Soviet Union, Cuba faced a severe economic downturn in the 1990s, known as the Special Period. During the 1970s through the late 1980s, Cuba intervened in numerous conflicts in support of anti-colonial and Marxist governments or movements across Africa, Latin America, and the Middle East. The country under Castro was a point of contention during the Cold War between the Soviet Union and the United States, and the Cuban Missile Crisis of 1962 is widely considered the closest the Cold War came to escalating into nuclear war.

I didn’t realize ChatGPT could do this — 10 best hidden features to try now

In March 2023, a bug allowed some users to see the titles of other users’ conversations. Despite this, users may jailbreak ChatGPT with prompt engineering techniques to bypass these restrictions. A 2023 analysis estimated that ChatGPT hallucinates around 3% of the time.

• The most rugged range is the Sierra Maestra, which stretches approximately 150 miles (240 km) along the southeastern coast and reaches the island’s highest elevations—6,476 feet (1,974 metres) at Turquino Peak and 5,676 feet (1,730 metres) at Bayamesa Peak.
• ChatGPT has never been publicly available in China because OpenAI prevented Chinese users from accessing their site.
• The rapid growth of tourism during the Special Period had widespread social and economic repercussions in Cuba, and led to speculation about the emergence of a two-tier economy.
• Cuba is the third-most populous country in the Caribbean after Haiti and Dominican Republic, with about 10 million inhabitants.
• Sand and clay plains cover parts of the north, a gravel bed takes up most of the southern part of the island, and bogs dominate the coasts and sparsely inhabited interior.

Cuba’s “Special Period” saw the country relying heavily on foreign tourism and the earnings of nationals working abroad. This signifies a 13% loss of population since 2012, when the Cuban population peaked at 11.2 million. On 9 September 1994, the U.S. and Cuban governments agreed that the U.S. would grant at least 20,000 visas annually in exchange for Cuba’s pledge to prevent further unlawful departures on boats. Those who left the country typically did so by sea, in small boats and fragile rafts. As of 2015, the foreign-born population in Cuba was 13,336 inhabitants per the World Bank data.

In September 2025, following the suicide of a 16-year-old, OpenAI said it planned to add restrictions for users under 18, including the blocking of graphic sexual content and the prevention of flirtatious talk. These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. The reward model of ChatGPT, designed around human oversight, can be over-optimized and thus hinder performance, in an example of an optimization pathology known as Goodhart’s law. In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations. The importance of the sugar harvest has declined, with tourism, tobacco, nickel, and pharmaceuticals surpassing sugar in economic importance. Cuba ranks as the fifth-largest producer of refined cobalt in the world.
In September 2024, OpenAI introduced o1-preview and a faster, cheaper model named o1-mini. OpenAI has not revealed technical details and statistics about GPT-4, such as the precise size of the model. Generative Pre-trained Transformer 4 (GPT-4) is a large language model developed by OpenAI and the fourth in its series of GPT foundation models. In August 2024, OpenAI announced it had created a text watermarking method but did not release it for public use, saying that users would go to a competitor without watermarking if it publicly released its watermarking tool. Shortly after the bug was fixed, users could not see their conversation history. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.
Grau further corroded the base of the already teetering legitimacy of the political system, particularly by undermining the Congress and Supreme Court. He is, as of 2004, the only non-white Cuban to win the nation’s highest political office. Grau resigned in 1934, leaving the way clear https://www.betybets.nl/ for Batista, who dominated Cuban politics for the next 25 years, at first through a series of puppet presidents. A five-member executive committee (the Pentarchy of 1933) was chosen to head a provisional government.

In August 2024, the FTC voted unanimously to ban marketers from using fake user reviews created by generative AI chatbots (including ChatGPT) and influencers paying for bots to increase follower counts. The FTC asked OpenAI for comprehensive information about its technology and privacy safeguards, as well as any steps taken to prevent the recurrence of situations in which its chatbot generated false and derogatory content about people. In October 2025, OpenAI banned accounts suspected to be linked to the Chinese government for violating the company’s national security policy. OpenAI said it has taken steps to effectively clarify and address the issues raised; an age verification tool was implemented to ensure users are at least 13 years old. A shadow market has emerged for Chinese users to get access to foreign software tools.

Political readjustments (1991–present)

Several well-known Cuban religious figures have operated outside the island, including the humanitarian and author Jorge Armando Pérez.

The chatbot can assist patients seeking clarification about their health. The uses and potential of ChatGPT in health care has been the topic of scientific publications and experts have shared many opinions. The Guardian questioned whether any content found on the Internet after ChatGPT’s release “can be truly trusted” and called for government regulation. The ChatGPT-generated avatar told the people, “Dear friends, it is an honor for me to stand here and preach to you as the first artificial intelligence at this year’s convention of Protestants in Germany”. In June 2023, hundreds of people attended a “ChatGPT-powered church service” at St. Paul’s Church in Fürth, Germany. In an industry survey, cybersecurity professionals argued that it was attributable to cybercriminals’ increased use of generative artificial intelligence (including ChatGPT).

This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT. In the 2020s, the rapid advancement of deep learning-based generative artificial intelligence models raised questions about the copyright status of AI-generated works, and about whether copyright infringement occurs when such are trained or used. Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence.
