Gemini 2.5 Pro vs Claude Fable 5.2 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Google / Gemini 2.5 Pro
proDescription
Google's previous flagship reasoning model remains effective across code, mathematics, and STEM. Gemini 2.5 Pro reads text, images, audio, video, and PDFs, and holds a million tokens of context, so entire codebases and document sets fit in one session. A thinking model built for complex problems rather than quick answers. Superseded by newer Gemini releases, though the capability set remains broad.
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.

Google / Gemini 2.5 Pro
proCoding Across Large Repositories
Google describes it as reasoning over complex problems in code, and says it can comprehend entire code repositories. Built for understanding a whole system rather than editing one file inside it.
A Thinking Model by Design
Google calls this a thinking model, meaning it reasons through a problem before answering rather than generating straight through. Aimed at maths, STEM, and problems where the route to the answer matters.
Room for Whole Codebases
A one-million-token context window. Load a full repository, a research corpus, or dozens of PDFs and ask questions across all of it without chunking the input into separate requests.
Writing From Dense Source Material
Strongest when writing from something rather than from nothing. Give it the datasets, papers, or documents and it will produce structured output grounded in what you supplied.
Analysis Over Large Datasets
Google names analysing large datasets, codebases, and documents as a core use. Suited to synthesis across many sources at once, where the volume of material is the hard part.
Audio, Video, Images, and PDFs
Google's own model page lists audio, images, video, text, and PDF as accepted inputs. One of the broadest input ranges available, and unusual in accepting both audio and video.
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.
