Claude Fable 5
Grok 4.6Anthropic's most capable widely released model, for the most demanding reasoning and long-horizon agentic work（This model is extremely expensive and is not recommended for casual use.）
Grok 4.6 is xAI’s (SpaceXAI) flagship multimodal reasoning model for coding, long-running agents, knowledge work, and interactive application development. It supports image understanding, a 500K context window, tool calling, and structured outputs. Compared with Grok 4.5, it offers stronger multi-step execution, self-verification, coding, and visual project generation.
Prices are per million tokens. Time to First Token and throughput are rolling averages measured on AIHubMix.
