Kimi K3.1 Pro

« Choose between two models optimized for professional work, coding, and using tools. They improve speed and significantly reduce costs compared to the previous generation »

« 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 powerful LLM model designed for coding, research, and long-running agentic tasks, featuring 500,000 tokens of context, tool calls, and fine-tuned reasoning effort. Available directly in Cursor and Grok Build »

« The OpenAI model capable of operating a computer like a human: filling out forms, managing a CRM, coding, analyzing scientific data, or conducting research. With a context of 1 million tokens »

« An AI model built for code and autonomous agents. It features a context window of one million tokens and enables detailed analysis of documents, charts, and screenshots. It is 40% less expensive than its predecessor (Opus 5) »

« Anthropic's LLM model for coding, research, and long, complex tasks. With improved performance and reduced costs on agent-based workloads. It also produces far fewer false security alerts »

« A fast and cost-effective model designed for code, agents, and complex workflows, with a 1-million-token context and significant improvements on long-running tasks and multi-step execution. Compared to its predecessor, this model scores 9 points higher on FrontierCode 1.1 and 16 points higher on DeepSWE v1.1 »

« An upgraded version that comes close to the intelligence of the GPT-6 Astra model at about one-fifth the cost. Enjoy better results in programming, writing, and agent-based tasks. You’ll also benefit from a context size exceeding one million tokens »
