Perplexity AI is an American web search engine that leverages large language models (LLMs) to process user queries and synthesize responses. Unlike traditional search engines, Perplexity aims to provide direct, accurate, and real-time answers, often citing its sources directly. It functions as an AI-powered answer engine, designed to cut through clutter and deliver credible, up-to-date information. The platform is versatile, serving as a tool for answering questions, learning new skills or concepts, and conducting in-depth research. It offers various underlying models, including a lightweight, cost-effective search model for quick, grounded answers, and an offline chat model that provides local AI capabilities without requiring internet search. Perplexity also integrates advanced third-party AI models like OpenAI's GPT-4 Omni and Anthropic's Claude 3.5 Sonnet & Haiku for its premium users. Perplexity is accessible across multiple platforms, including a web application, and dedicated mobile apps for Android and iOS. It also offers a developer API, notably including its proprietary 'Sonar' models, allowing external applications to integrate Perplexity's AI search capabilities. The service operates on a freemium model, offering a free plan with core features and a 'Pro' subscription for enhanced capabilities.

Gemini is Google's family of highly capable and general-purpose generative AI models, developed by Google's AI research labs, DeepMind and Google Research. It is designed to be inherently multimodal, meaning it can seamlessly understand, operate across, and combine different types of information, including text, images, audio, video, and code. The Gemini model family is optimized for various use cases and sizes, ranging from highly efficient models for on-device deployment (Nano) to the most powerful and complex models for advanced reasoning (Ultra). It offers advanced capabilities such as native tool use, in-depth research, technical accuracy, creative writing, and robust coding assistance. The models are continuously updated with improvements in generative AI capabilities and expanded access. Gemini is available to developers via the Gemini API, Google AI Studio, and Vertex AI, allowing integration into various applications and services. It also powers the Gemini mobile app, serving as an AI assistant on Android and iOS devices, offering features like real-time conversation, image creation, and live interaction with camera and screen sharing to enhance creativity and productivity.

Llama is a family of large language models (LLMs) developed by Meta AI. First introduced in February 2023, these models are designed with an open-source philosophy, allowing developers to fine-tune, distill, and deploy them across various environments. This open approach fosters a broad ecosystem for AI innovation and application development. While initially focused on advanced text generation tasks, the Llama family has evolved significantly. Recent iterations, such as Llama 3.2 and the latest Llama 4, have expanded into multimodal capabilities. This means they can process and understand not only text but also integrate and analyze image and video data, making them versatile for a wide array of applications, including vision-related AI, edge computing, and conversational AI assistants. Llama models are made available under a license that supports broad commercial use, encouraging developers to build and redistribute additional work on top of the models. While the core models are generally free for use, API access for certain versions, particularly through cloud platforms like Google Cloud's Vertex AI, operates on a paid, per-token billing model. The availability of lightweight Llama models also facilitates their deployment on mobile devices, enhancing accessibility and enabling on-device AI functionalities.
