GPT-5 is our flagship model for coding, reasoning, and agentic tasks across domains. The best model for coding and agentic tasks with higher reasoning capabilities and medium speed.
Claude Opus 4.1 is a hybrid reasoning model that pushes the frontier for coding and AI agents, featuring a 200K context window. It delivers superior performance and precision for real-world coding and agentic tasks, handling complex multi-step problems with rigor and attention to detail. With extended thinking capabilities, it offers instant responses or extended step-by-step thinking visible through user-friendly summaries. It advances state-of-the-art coding performance to 74.5% on SWE-bench Verified, excels at agentic search and research, and produces human-quality content with exceptional writing abilities. It supports 32K output tokens and adapts to specific coding styles while delivering exceptional quality for extensive generation and refactoring projects.
Claude Sonnet 4, part of the Claude 4 family, is a significant upgrade to Claude Sonnet 3.7. It excels in coding (72.7% on SWE-bench) and reasoning, responding more precisely to instructions. Sonnet 4 offers an optimal mix of capability and practicality, with enhanced steerability, and supports extended thinking with tool use.
Claude Opus 4 is Anthropic's most powerful model and the world's best coding model, part of the Claude 4 family. It delivers sustained performance on complex, long-running tasks and agent workflows. Opus 4 excels at coding, advanced reasoning, and can use tools (like web search) during extended thinking. It supports parallel tool execution and has improved memory capabilities.
The most intelligent Claude model and the first hybrid reasoning model on the market. Claude 3.7 Sonnet can produce near-instant responses or extended, step-by-step thinking that is made visible to the user. Shows particularly strong improvements in coding and front-end web development.
GLM-4.6 is the latest version of Z.ai's flagship model, bringing significant improvements over GLM-4.5. Key features include: 200K token context window (expanded from 128K), superior coding performance with better real-world application in Claude Code/Cline/Roo Code/Kilo Code, advanced reasoning with tool use during inference, stronger agent capabilities, and refined writing aligned with human preferences. GLM-4.6 achieves competitive performance with DeepSeek-V3.2-Exp and Claude Sonnet 4, reaching near parity with Claude Sonnet 4 (48.6% win rate) on CC-Bench real-world coding tasks.
DeepSeek-V3.2-Exp is an experimental iteration introducing DeepSeek Sparse Attention (DSA) to improve long-context training and inference efficiency while keeping output quality on par with V3.1. It explores fine-grained sparse attention for extended sequence processing.
GLM-4.5 is an Agentic, Reasoning, and Coding (ARC) foundation model designed for intelligent agents, featuring 355 billion total parameters with 32 billion active parameters using MoE architecture. Trained on 23T tokens through multi-stage training, it is a hybrid reasoning model that provides two modes: thinking mode for complex reasoning and tool usage, and non-thinking mode for immediate responses. The model unifies agentic, reasoning, and coding capabilities with 128K context length support. It achieves exceptional performance with a score of 63.2 across 12 industry-standard benchmarks, placing 3rd among all proprietary and open-source models. Released under MIT open-source license allowing commercial use and secondary development.
Our most intelligent AI model, built for the agentic era. Gemini 2.5 Pro leads on common benchmarks with enhanced reasoning, multimodal capabilities (text, image, video, audio input), and a 1M token context window.
