Overview
MiMo-V2.5-Pro vs Claude Fable 5.1 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
MiMo / MiMo-V2.5-Pro
allDescription
Xiaomi’s flagship, built for autonomous work that runs for hours rather than seconds. MiMo-V2.5-Pro sustains trajectories spanning thousands of tool calls, holding coherence across a million-token context. Xiaomi reports it building a full compiler unaided in a few hours. It is also unusually token-efficient, reaching comparable results while spending far less. Text only. Open weights under a permissive licence.
Anthropic / Claude Fable 5.1
maxDescription
Anthropic's most capable generally available model, sitting above the Opus line. Fable 5.1 is built for long, unsupervised work: multi-day coding, agentic research, and tasks that run across dozens of tool calls. It reads text and images, maintains a very large context, and reasons before every answer at an adjustable depth. Its knowledge is the most recent of any Claude model. Anthropic positions Opus 5 as the starting point for most work, and Fable 5.1 for teams whose evaluations demand a higher ceiling.

Why Use MiMo-V2.5-Pro and Claude Fable 5.1?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
MiMo / MiMo-V2.5-Pro
allHours-Long Software Engineering
Xiaomi documents it writing a complete compiler from scratch across hundreds of tool calls with a perfect test score, and an eight-thousand-line video editor in a single autonomous run. Built for the whole job.
Reasoning With Harness Awareness
Xiaomi describes the model actively managing its own memory and shaping how its context fills as it works. In its own tests it diagnosed a regression it had caused, recovered, and carried on.
Usable Million-Token Context
Xiaomi's long-context testing shows it still retrieving accurately deep into a million tokens where its predecessor collapses entirely. The capacity is proven rather than merely advertised.
Structured Artifact Generation
Its coding evaluation covers repository understanding, project building, code review, structured artifact generation, and planning. Strongest when producing something with a shape rather than free-flowing prose.
Research Through Tool Use
Built to call tools, read results, and adjust. Xiaomi demonstrated it driving a circuit simulator in a closed loop, reading waveforms and tuning parameters until every target was met. No native web search.
Text Only Input
Reads and writes text. No image, audio, or video input. Screenshots, mockups, diagrams, and scanned pages are outside what this model can read.
Anthropic / Claude Fable 5.1
maxLong-Running Coding
Anthropic's strongest model for multi-day coding sessions and codebase research. Built to sustain complex software engineering across many steps and tool calls without a human checking in at each one.
Adaptive Thinking Always On
Reasoning is always on, with adjustable effort rather than an on-off switch. Steer depth up for the hardest problems or down for lighter work, without restructuring the prompt each time.
Room For Whole Projects
A very large context window, among the largest available. Load an entire codebase, a long research corpus, or a large document set and work across all of it in a single session.
Document-Heavy Analysis
Built for document-heavy analysis and multi-step automation alongside coding. Suited to work that reads across large, mixed source material and produces structured, reviewable output.
Long-Horizon Agent Work
Its defining strength. Retains context, uses tools, evaluates results, and works on a task through many steps. Built for agents who run for a long time with little supervision.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots, diagrams, or scanned pages alongside your question. Output is text only. Audio and video are not accepted.
