Meet Kimi K2.5 and its API access
Kimi K2.5 is Moonshot AI's model released on January 27, 2026, with open-source weights on Hugging Face and GitHub. It is positioned as visual agentic intelligence — a qualitative shift toward real-world execution rather than single-task assistance. It natively processes text, images, and video, converts designs and screenshots into high-fidelity front-end code, and runs across four operating modes, including an Agent Swarm that coordinates up to 100 sub-agents in parallel. Velokey provides an affordable, easy-to-integrate Kimi K2.5 API: a unified chat endpoint, a clear request flow, and below-list pricing for production systems, agent pipelines, and automation tools.
High-fidelity visual coding
Converts designs and screenshots into functional front-end code with high fidelity, turning static mockups into working UI so you can go from a visual reference to a running website directly.

Agent Swarm with up to 100 sub-agents
Coordinates up to 100 AI sub-agents in parallel, reducing execution time by up to 4.5x — built for large-scale research, batch operations, and multi-source deep investigation.
View Documentation →
Four operating modes
Runs in Instant, Thinking, Agent, and Agent Swarm modes, letting you trade off fast responses, deliberate reasoning, single-agent tool use, and massively parallel execution per task.
View Documentation →
Independent tool use & content generation
Uses tools independently — search, generation, analysis, organization — and generates documents (Word, LaTeX PDFs), presentations, spreadsheets, websites, and research reports.
