GLM-4.7-Flash vs Claude Fable 5.2 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Z AI / GLM-4.7-Flash
proDescription
Z.ai’s lightweight model is an unusually capable one for its size. GLM-4.7-Flash activates only a small fraction of its parameters per token, making it fast and inexpensive to run. Z.ai claims open-source leadership in its size class on coding, with strong front-end and back-end work. Text only. Open weights are small enough to run on your own hardware.
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 GLM-4.7-Flash 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.
Z AI / GLM-4.7-Flash
proCoding Above Its Class
Z.ai says it achieves open-source state of the art among models of comparable size, with superior front-end and back-end development. The GLM-4.7 line is tuned for UI quality and cleaner layouts.
Reasoning Per Turn
Round-level reasoning lets you disable thinking on simple turns to cut latency and enable it on complex ones for accuracy. Reasoning blocks persist across turns, which steadies long tasks.
Long-Form Text Processing
Z.ai names long-form text processing among its recommended uses. Handles extended documents and sustained conversations, though it is not built for the whole-repository work larger models take on.
Writing And Translation
Z.ai recommends it beyond coding for writing, translation, and character interaction. That last one is unusual for a vendor to name, and it points to strength in holding a consistent voice.
Analysis Without Search
Reads and analyses whatever you supply. Multi-turn tool calling is supported, so tools can be connected, but there is no native web search and current information has to come from you.
Text Only Input
Reads and writes text. No image, audio, or video input. Screenshots, diagrams, mockups, and scanned pages are outside the scope of this model.
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.
