MoonshotAIMoonshotKimi K3

Moonshot flagship model with native vision and up to a 1M-token context window. It currently runs at max reasoning effort and suits long-horizon coding, knowledge work, and complex tasks that coordinate terminal tools. For stable use, preserve the full reasoning history and start a new session in a compatible agent harness.

$2.7/1M tokensMoonshotAIMoonshotKimi K3.1 PRO Highspeed

Choose this when you want Kimi K3.1 Pro capabilities with more responsive output. It keeps the roughly 1-million-token context, image and video input, and required thinking mode; the official estimate is about 2–3× the speed, at roughly twice the quota usage.

$3.78/1M tokensClaudeAnthropicClaude Opus 5 5

Built for long-running agentic coding and knowledge work, especially cross-file refactors, codebase audits, and complex multi-step tasks. Its 1M-token context, always-on adaptive thinking, and text/image input favor high-quality long-horizon execution; compared with Sonnet 5, it prioritizes depth at higher cost and latency.

$1.36/1M tokensDeepSeekDeepSeekDeepSeek V4 Flash

Built for reasoning, coding, and agentic tool use, with stronger long-context, thinking-mode, and complex-task execution than DeepSeek V3.2. Compared with Chinese peers such as Qwen, GLM, and Kimi, it is especially competitive for math, programming, and logical reasoning tasks.
