The largest is the Zapata Swamp, with over 4,520 km2 (1,750 sq mi). Other mountain ranges are Sierra Cristal in the southeast, Escambray Mountains in the center of the island, and Sierra del Rosario in the northwest. The lowest point is the Caribbean Sea at 0 m (sea level) and the highest point is Pico Turquino at 1,974 m (6,476 ft), part of the Sierra Maestra mountain range, located in the southeast of the island. The northeastern shore is lined by the Sabana-Camagüey Archipelago, which includes Jardines del Rey and is composed of approximately 2,517 cays and islands.
In November 2023, OpenAI released GPT Builder a tool for users to customize ChatGPT’s behavior for a specific use case. However, no machine translation services match human expert performance. In December 2023, the Albanian government decided to use ChatGPT for the rapid translation of European Union documents and the analysis of required changes needed for Albania’s accession to the EU. According to the company, Plus provided access during peak periods, no downtime, priority access to new features, and faster response speeds. In December 2024, OpenAI launched a new feature allowing users to call ChatGPT with a telephone for up to 15 minutes per month for free. GPT-based moderation classifiers are used to reduce the risk of harmful outputs being presented to users.

ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history. In The Atlantic magazine’s “Breakthroughs of the Year” for 2022, Derek Thompson included ChatGPT as part of “the generative-AI eruption” that “may change our https://www.betybets.nl/ mind about how we work, how we think, and what human creativity is”. Samantha Lock of The Guardian noted that it was able to generate “impressively detailed” and “human-like” text. Released in February 2025, GPT-4.5 was described by Altman as a “giant, expensive model”. O1 is designed to solve more complex problems by spending more time “thinking” before it answers, enabling it to analyze its answers and explore different strategies.

When compared to similar chatbots at the time, the GPT-4 version of ChatGPT was the most accurate at coding. In January 2023, the International Conference on Machine Learning banned any undocumented use of ChatGPT or other large language models to generate any text in submitted papers. In January 2023, Science “completely banned” LLM-generated text in all its journals; however, this policy was just to give the community time to decide what acceptable use looks like. Additionally, using a model’s outputs might violate copyright, and the model creator could be accused of vicarious liability and held responsible for that copyright infringement. Popular deep learning models are trained on mass amounts of media scraped from the Internet, often utilizing copyrighted material. As of 2023, there were several pending U.S. lawsuits challenging the use of copyrighted data to train AI models, with defendants arguing that this falls under fair use.
Emigration has continued into the 2020s, with the national population dipping below 10 million for the first time since 1980 in 2025. Internal migration has led to overpopulation in Havana, resulting in people living in makeshift shelters or overcrowded buildings, some of which are on the brink of collapse.

If you want ChatGPT to think longer to improve the accuracy of its answers then you can select Thinking or Thinking mini from the model picker. OpenAI’s, ChatGPT-5 model can work across any combination of text, audio and images meaning many more applications for AI are now possible. OpenAI’s ChatGPT is leading the way in the generative AI revolution, quickly attracting millions of users, and promising to change the way we create and work. In the UK, a judge expressed concern about self-representing litigants wasting time by submitting documents containing significant hallucinations. In November 2025, OpenAI acknowledged that there have been “instances where our 4o model fell short in recognizing signs of delusion or emotional dependency”, and reported that it is working to improve safety.
Near the centre of the island are the Santa Clara Highlands, the Sierra de Escambray (Guamuhaya), and the Sierra de Trinidad. 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. In general, the island runs from northwest to southeast and is long and narrow—777 miles (1,250 km) long and 119 miles (191 km) across at its widest and 19 miles (31 km) at its narrowest point.

It has been described as a crisis that is “threatening the stability” of Cuba, which “already has one of the hemisphere’s oldest populations”. According to Carmelo Mesa-Lago, there is widespread consensus that the policies of the revolutionary government decreased poverty until the end of the Cold War.
