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
3 represents the latest evolution in xAI's suite of large language models, specifically targeting developers and data science professionals. 20, while introducing a refined architecture aimed at enhancing efficiency and output quality.
One of its most significant updates is the expanded knowledge base, which now includes information through December 2025, making it a competitive choice for tasks requiring awareness of recent global events and technical developments. As the model is currently in a gradual rollout phase, users can expect iterative updates to its stability and reasoning capabilities.
3 is designed to handle sophisticated model training and deployment scenarios, offering a frontier-class alternative for those integrated into the xAI ecosystem. Buyers should evaluate its performance specifically against their unique datasets during this beta period to determine its suitability for production-ready applications.

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
Take advantage of Anthropic’s AI model—more reliable, more honest, and four times less likely to overlook its own errors. Its fast mode delivers up to 2.5 times more tokens per second (at the same API rate as the previous version)
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
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)
Tackle time-consuming and complex tasks by letting AI plan, use tools, check its work, and see tasks through to completion with minimal supervision. This model significantly improves coding, the use of virtual machines, online research, and knowledge work tasks

Use a more reliable and accurate ChatGPT. This new model significantly reduces hallucinations on sensitive topics (medicine, law, finance). It provides shorter responses and offers greater personalization based on your files, past conversations, and connected Gmail account
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
This open-source model takes agent-based programming even further with multi-file editing, 256K of context, and the generation of animated front-end interfaces. It also features swarms of up to 300 sub-agents capable of performing tasks continuously
This version of Grok brings together four professor-level agents who reason together before responding. They correct each other, break down problems, and rely on real-time web search and coding tools to provide more reliable answers
Run a 35-billion-parameter MoE model with only 3 billion parameters actually activated, while achieving coding, vision, and reasoning performance on par with much larger models. Optimized for agentic coding, multimodal perception, and very long contexts (up to over a million tokens)
