Kimi K2.5 is Moonshot AI's native multimodal model, released 2026-01, built on Kimi K2 with continued pretraining over roughly 15T mixed visual and text tokens. It targets visual coding, agentic tool calling, and self-directed agent swarms.
Capabilities
Channels
Same weights on every channel. Requests route to the cheapest healthy one; the channel used is printed on each billing line.
Cost Calculator
Pick a channel and a usage scenario, then drag to your workload — each scenario assumes a different prompt-cache hit rate.
Benchmarks
bar = score (0–100) · ▏ medianScores from vendor reports and public leaderboards. No private evals.
Showcase
Three fixed prompts, identical for every chat model. Outputs are archived verbatim — copy the prompt to reproduce.
Build a single-file HTML page using three.js from a CDN: a low-poly planet with a tilted ring of ~200 orbiting particles, a soft key light plus rim light, slow auto-rotation, and drag-to-orbit controls. No build tools — one file only.
Every model will run this exact prompt; the output lands here verbatim, with tokens and per-run cost.
Find the sum of all positive integers n such that n² + 85n + 2017 is a perfect square. Show your reasoning, then give only the final answer on the last line.
Every model will run this exact prompt; the output lands here verbatim, with tokens and per-run cost.
Extract strict JSON {vendor, invoice_no, issue_date, currency, total, line_items:[{desc, qty, unit_price}]} from the invoice text. Output JSON only.
