Perplexity

Perplexity offers an AI-powered research tool that combines the conversational capabilities of large language models (LLMs) with real-time web search functionality. Unlike traditional search engines that return lists of links or standalone AI chatbots that rely solely on training data, Perplexity provides direct answers to queries while citing specific sources. The platform distinguishes itself through this commitment to transparency and source attribution. Every response includes citations to the specific sources used, allowing users to verify information and explore original materials.

Llama

Meta’s Llama family of LLMs marked a significant shift in the landscape, as they were released as open-source. These models enabled users, researchers, and developers to run them locally on a computer. The Llama 3 family includes models of various sizes (ranging from 8 to 405 billion parameters), each optimised for different use cases and computational constraints. Their open nature has led to numerous derivatives and improvements, significantly democratising access to powerful language models. Users can try Llama on Meta AI, a chat interface that runs the models.

Grok

Grok, developed by xAI, was first developed in August 2023 and released in November 2023 (with Grok-1) as a direct competitor to other LLMs. The model was trained on data from X (formerly Twitter) and aims to differentiate itself with a more casual, witty communication style and real-time access to X’s data. It was made available through X’s premium subscription service (X Premium+) before the Grok-2 model became accessible to all X users in December 2024. On February 17, 2025, xAI released its latest flagship AI model, Grok-3, along with other updates to the Grok platform.

Mistral

The Mistral family of models, created by Mistral AI, has gained attention for achieving impressive performance with more efficient architectures. Their lineup of models is notable for matching or exceeding the performance of much larger models while requiring fewer computational resources. The Mistral models are accessible via the assistant, Le Chat, which offers features including web search, image generation, and real-time updates.
