BlockBeats News, July 22nd, AI payment infrastructure Kite ecosystem launched Marathon, an adaptive reasoning infrastructure for long-running AI Agents. Users can select a completion window for each request (now / soon / later / anytime), with a lower price for longer waiting times; the deepest tier can save up to approximately 65% compared to real-time prices (discount is an estimate and may vary with real-time capacity). The service API is compatible with OpenAI and provides a one-line command install plugin for Claude Code and Codex. The initial support includes five flagship open-weight models: Kimi K3, GLM 5.2, DeepSeek V4 Pro, Qwen3.6-35B-A3B, and Nemotron 3 Ultra, all subject to the same pricing rules. For more information, visit the official website marathon.build.

It is reported that Kite previously completed a $33 million financing round led by PayPal Ventures and General Catalyst. The launch of Marathon is a key move for Kite to extend from an Agent identity and payment network to Agent Economy's underlying computational power infrastructure, aiming to establish a complete loop for Agents with "self-triggered calls and self-payment."
