Grok 4.5 vs Claude Opus 4.8 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
xAI / Grok 4.5
proDescription
Grok 4.5 is xAI's newest model, built primarily for coding and agentic work. Its training drew on real developer session data, including debugging traces and multi-file code changes, rather than static code alone, which xAI points to as the reason for its strength on real-world coding tasks.
Anthropic / Claude Opus 4.8
maxDescription
Anthropic's flagship is built for work that other models get wrong. Opus 4.8 takes on the hardest coding, the deepest analysis, and writing that has to be right first time. It reads images and documents, holds a very large amount of context at once, and works through problems step by step so you can follow its logic. Slower and more expensive than lighter models, by design.

Why Use Grok 4.5 and Claude Opus 4.8?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
xAI / Grok 4.5
proEfficient Coding
Get coding help that xAI reports completes tasks using far fewer output tokens than comparable frontier models, aimed at keeping speed and cost down without sacrificing quality.
App Building
Describe an application in a single prompt and get a working build back, based on xAI's own demonstrations of the model generating functional apps end to end.
Office File Work
Get help with Word, Excel, and PowerPoint files, including building native PowerPoint shapes for diagrams rather than plain text placeholders.
Agentic Tasks
Hand it multi-step, tool-using tasks modeled on real developer workflows, drawing on training data that included debugging traces and multi-file code changes.
Legal Document Work
Work through legal documents and agent-style legal tasks, an area where xAI reports the model ranking at the top of a dedicated legal benchmark.
Lower-Cost Coding
Get frontier-level coding support aimed at a lower cost per task than comparable top-tier models, based on xAI's published efficiency figures.
Anthropic / Claude Opus 4.8
maxCoding Assistance
Best-in-class. Handles large refactors, subtle bugs, and unfamiliar codebases. Built for the code that defeats lighter models, not routine changes.
Reasoning & Problem Solving
Best-in-class. Works through multi-step problems in the open, showing its reasoning as it goes. Strongest where the answer is not obvious.
Document & File Understanding
Best-in-class. A one-million-token context window, roughly 750,000 words. Load a full contract set, research folder, or codebase and ask questions across all of it.
Writing & Content Creation
Best-in-class. Professional output that needs editing rather than rewriting. Holds tone and structure across long pieces, up to 128,000 tokens in a single response.
Research & Analysis
Best-in-class. Reads dense, contradictory, or ambiguous material and forms a judgment. The strongest choice when the analysis itself is the hard part.
Multimodal Support
Text and images. Anthropic's documentation lists text and image input for all current Claude models. Audio and video input are not listed. Reads PDFs, spreadsheets, contracts, and code files.
