Gemini is a family of multimodal large language models developed by Google DeepMind, designed to be a successor to LaMDA and PaLM 2. It was announced on 10 May 2023 and launched on 6 December 2023. Key aspects of Gemini include:

• Multimodality: Gemini is designed to process various data types simultaneously, including text, images, audio, video, and computer code. It can handle these different modes in any order, allowing for flexible input and output.
• Model Variants: The first generation of Gemini ("Gemini 1") includes three models: Gemini Ultra (for complex tasks), Gemini Pro (for a wide range of tasks), and Gemini Nano (for on-device tasks). The second generation ("Gemini 1.5") includes Gemini 1.5 Pro and Gemini 1.5 Flash.
• Performance: Gemini Ultra has been reported to outperform other models, including GPT-4, on various industry benchmarks and was the first language model to surpass human experts on the Massive Multitask Language Understanding (MMLU) test. Gemini Pro has been said to outperform GPT-3.5. Gemini 2.0 Flash has outperformed 1.5 Pro on key benchmarks, while also being faster.
• Updates and Evolution:
• Gemma, a family of free and open-source LLMs serving as a lightweight version of Gemini, was released in February 2024.
• Gemini 2.0 Flash Experimental was released in December 2024, with improved speed and performance.
• Gemini 2.0 Flash became the default model in January 2025, with Gemini 1.5 Flash still available.
• Technical Details:
• Agentic Capabilities:
• Training Data: Gemini's dataset is multimodal and multilingual, including web documents, books, code, images, audio, and video data. It was also trained using transcripts of YouTube videos, with lawyers filtering out potentially copyrighted material.
• Reception: Gemini's launch was highly anticipated, with some predicting it would surpass GPT-4. However, some experts have cautioned about interpreting benchmark scores without full insight into the training data. Google has also faced criticism for a demonstrative video of Gemini that was not conducted in real time.
• Safety and Responsibility: Google has emphasised that it is committed to building AI responsibly, with safety and security as key priorities.

Google DeepMind is also developing other related technologies, including Veo for video generation, Imagen for text-to-image generation, and AlphaFold for protein structure prediction.

Schizophrenia is a severe psychiatric condition that affects a person's mental and physical well-being by disrupting how their brain works, impacting thoughts, memory, senses and behaviours. It is characterised by a disconnection from reality that can include hallucinations and delusions. Schizophrenia is now viewed as a spectrum of conditions. Key aspects of schizophrenia include:

• Symptoms: Symptoms are categorised as positive, negative and cognitive. Positive symptoms include hallucinations and delusions. Negative symptoms are deficits of normal emotional responses, or of other thought processes, such as a flat affect, poverty of speech, inability to feel pleasure, lack of desire to form relationships and a lack of motivation. Cognitive symptoms affect memory, attention, and the ability to organise thoughts.
• Causes: The exact causes of schizophrenia are not fully known, but it is believed that a mix of genetics, brain chemistry and environmental factors play a part. Changes in certain brain chemicals, like dopamine and glutamate, may contribute to the condition. Neuroimaging studies show changes in the brain structure and central nervous systems of people with schizophrenia, which indicate that it is a brain disease.
• Risk factors: Several factors can increase the risk of developing schizophrenia, including genetic factors, such as a family history of the condition . Environmental risk factors include substance use, maternal obesity , and childhood adversity .
• Diagnosis: Diagnosis typically involves assessing symptoms over a period of time and ruling out other conditions. The criteria for diagnosis can vary, with the ICD criteria typically used in European countries and the DSM criteria used predominantly in the United States and Canada.
• Treatment: The primary treatment for schizophrenia is antipsychotic medication, often combined with psychosocial interventions and social support. Community support services, such as drop-in centers, mental health teams, and support groups are also common. Early diagnosis and treatment are important for better management of the condition. The time between the onset of psychotic symptoms and treatment is associated with a poorer outcome.
• Management: Management of schizophrenia involves a combination of medication, psychosocial interventions and community support. Assertive community treatment (ACT) and intensive care management (ICM) are approaches that provide support in the community, outside of the hospital setting, including assistance with routine matters.
• Stigma: There is considerable stigma associated with schizophrenia. Efforts have been made in some countries to reduce this stigma by changing the name of the condition.

It is important to note that proper treatment of schizophrenia can reduce the risk of suicide.

• Real-time Flight Map: The service displays aircraft moving on a detailed map. Users can view flight details by tapping on an aircraft, including route, estimated time of arrival, aircraft type, speed, and altitude.
• Historical Flight Data: Users can view historical data and watch playbacks of past flights.
• App Features: Flightradar24 offers mobile apps for iOS and Android devices. These apps allow users to identify flights overhead by pointing their device at the sky. They also offer 3D views, search functionality, filters, and more.
• Subscription Options: While the basic app is free, there are Silver and Gold subscription options that provide access to additional features, such as more flight history, weather overlays, and aeronautical charts.
• Crowdsourced Data: The service relies heavily on crowdsourced data from volunteers who operate ADS-B receivers.
• Global Coverage: While most of the data is from crowdsourced ADS-B receivers, coverage is also supplemented by radar data, especially in the US, Canada, and Australia.
• Entertainment Purposes: The apps are intended for entertainment and not for any activity that could endanger lives.
