Kimi K2.5 vs Claude Fable 5.2 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Kimi / Kimi K2.5
proDescription
Moonshot AI's previous flagship, and the model that brought vision to the Kimi line. K2.5 turns UI designs and visual specifications into working code and can spin up parallel sub-agents that split a task across many workers at once rather than processing it in sequence. It reads text and images; video is still experimental. Open weights under a modified MIT license
Anthropic / Claude Fable 5.2
maxDescription
Anthropic's most capable model and the upgrade to Fable 5.1. Anthropic reports it is a step above Opus 5.5 in almost every area it tested, with large gains in coding and chart reading, and output up to 30% faster than Fable 5.1. It reads text, images, and files across a very large context, supports web search, and offers effort from Low to Max.

Why Use Kimi K2.5 and Claude Fable 5.2?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
Kimi / Kimi K2.5
proCoding From Visuals
Its headline capability. Moonshot says K2.5 generates code from visual specifications such as UI designs and video workflows, and orchestrates tools for visual data processing. Hand it a mockup, get an interface.
Instant And Thinking
Two modes: instant for fast answers with no reasoning trace, thinking for deliberation before responding. Thinking can be disabled per request, so you pay for reasoning only when a task warrants it.
Mid-Size Context Window
A mid-size context window. Enough for long documents, extended agent sessions, and substantial codebases, though a fraction of what the largest frontier models hold.
Documents From Agents
Its agent mode is built for office productivity, producing finished documents and spreadsheets rather than text you then assemble. Moonshot targets real-world knowledge work rather than chat.
Parallel Sub-Agent
Moonshot's agent swarm decomposes a task into parallel sub-tasks run by sub-agents it creates on the fly. Its built-in web search tool is currently incompatible with thinking mode and needs it disabled.
Images Native Video Experimental
Vision is native, pre-trained on visual and text tokens together rather than added afterwards. Moonshot describes video input but marks chat with video as experimental and limited to its own API.
Anthropic / Claude Fable 5.2
maxTop FrontierCode Score
Anthropic reports 49.1% on FrontierCode 2.0 at Xhigh effort, up from 32.4% for Fable 5.1. That is the highest score of any released model Anthropic tested.
Effort Low To Max
Effort runs Low, Medium, High, Xhigh, and Max, with Medium as the default. At Medium, Anthropic reports it finishes hard tasks with fewer tokens than Fable 5.1.
Room For Whole Projects
A very large context window on Aymo, with room for a full codebase or a long document set. Load everything once and work across it in one session.
Expert Technical Work
Anthropic built Fable for its most ambitious, open-ended technical work. It can also act as an advisor to smaller models or hand simpler tasks to them.
Fewer Needless Refusals
Supports web search on Aymo. Anthropic reports about 55% fewer blocked legitimate requests than Fable 5.1, with similar protection against cyber and biology risks.
Text, Image, And Files
Reads text and images, plus files you upload on Aymo. On Chartography, a chart-reading test without tools, Anthropic reports 73.4%, up from 44.8% for Fable 5.1.
