o3 Pro by OpenAI

« An open-source model designed for code and long-running tasks, with a context window of up to 1 million tokens. This Mixed Expert (MoE) LLM handles complex projects, analyzes entire repositories, and performs multi-step reasoning. It is available as open source under the MIT license »

« The OpenAI model built for long and complicated tasks. It has fewer hallucinations and improved multi-step reasoning. This LLM is great for creating tables, presentations, analyzing long documents, and coding »

« Anthropic's most powerful model, capable of handling contexts of 1 million tokens and reasoning adaptively. It coordinates multiple agents in parallel to solve complex tasks. You control the level of effort, intelligence, or cost with 4 available settings »

« The new beta version of the xAI model, which is comparable in size to Grok 4.20 but features an improved architecture and knowledge updated through December 2025, is already being rolled out gradually »

« This Mixture-of-Experts model, with approximately 1 trillion parameters, features a 1M-token context, virtually infinite Engram memory, and multimodal capabilities for text, images, and video. It aims to achieve performance scores comparable to Claude Opus while remaining significantly more affordable (to be released under the Apache 2.0 license) »

« A Google AI model capable of handling complex tasks involving text, images, audio, or video. It can summarize lengthy sources, analyze data, and assist in coding end-to-end interfaces »

« OpenAI's most powerful frontier model directly controls your computer, processes 1 million tokens, and reasons about very long tasks. It is claimed to reduce errors by 33% and significantly improve code and document analysis »

« Google's most intelligent multimodal model: advanced reasoning, deep contextual understanding, autonomous agents, visual coding, and Deep Think mode. It performs particularly well for agentic coding »
