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
2 enters the developer landscape as a specialized Large Language Model (LLM) designed for high-complexity coding and long-duration reasoning tasks. Utilizing a Mixture-of-Experts (MoE) architecture, this model is engineered to balance computational efficiency with deep analytical performance.
One of its most significant technical highlights is the massive 1-million-token context window, which potentially allows users to ingest entire software repositories or extensive technical documentation in a single prompt. This capability is particularly useful for developers who need to perform multi-step reasoning across large-scale projects without losing context.
2 offers a level of transparency and flexibility that is often restricted in proprietary models. Users should evaluate the model's performance on their specific hardware, as MoE architectures can require significant memory resources.
2 provides a robust foundation for advanced AI-driven development workflows.

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)
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
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
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)
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
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 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)

The 1-million-token context window allows GLM-5.2 to process vast amounts of data simultaneously. For developers, this means the ability to analyze entire codebases, long technical manuals, or complex project histories without truncating information. This facilitates more accurate multi-step reasoning and helps the model maintain consistency across large-scale software engineering tasks that smaller context windows might struggle to handle.
The MIT license provides significant freedom for both individual developers and enterprise teams. It allows users to modify, distribute, and use the model for commercial purposes with minimal restrictions. However, users should evaluate the infrastructure costs associated with running such a large Mixture-of-Experts model, as the free license does not include the hardware or cloud computing resources required for deployment.
