Grok 4.5 vs Perplexity Sonar Übersicht
Alles, was Sie über diese KI-Modelle wissen müssen, einschließlich Funktionen, Leistung, Preise und technische Details.
xAI / Grok 4.5
proBeschreibung
xAI's frontier model, built for coding, agentic tasks, and knowledge work rather than conversation. Grok 4.5 reads text and images, searches both the web and X, and lets you set how hard it thinks before answering. Its knowledge runs to February 2026, unusually recent. The tradeoff is context: its window is half the size of the previous Grok generation.
Perplexity / Perplexity Sonar
proBeschreibung
Perplexity’s search model is the only one that runs a web search on every single request. Sonar is built to answer questions with citations, not to reason or write code. It formulates the query, retrieves sources, evaluates them, and synthesizes a cited answer in one pass. Fast, cheap, and factual. A specialist rather than a general-purpose model, and it should be judged as one.

xAI / Grok 4.5
proCoding and Agentic Tasks
xAI was built specifically for coding and agentic tasks, trained on new datasets spanning science, engineering, and maths. Aimed at multi-file work across repositories.
Reasoning Effort You Control
Reasoning runs at low, medium, or high, so you decide how much thinking each request gets. Function calling and code execution are supported, which is what agentic work actually depends on.
A Mid-Size Context Window
Handles 500,000 tokens, roughly 375,000 words. Comfortable for large codebases and long document sets, though half the window the previous Grok generation offered, so whole-monorepo work may not fit.
Knowledge Work and Documents
xAI positions it for knowledge work alongside coding, which means long documents, structured reasoning, and the kind of writing that has to survive review rather than just read well.
Web Search and X Search
xAI states plainly that Grok knows nothing beyond its training data, and provides server-side Web Search and X Search tools to fix that. X Search is unique to this model.
Text and Image Input
Reads text and images, in jpg or png, in any order alongside your prompt. Send screenshots, diagrams, or scanned pages. Audio and video are not listed as supported inputs.
Perplexity / Perplexity Sonar
proNot Built for Coding
Sonar is a search-to-answer system, not a coding model. It will answer questions about code by finding documentation and discussion, but it is not intended for writing, refactoring, or debugging software.
Retrieval Over Reasoning
Perplexity positions Sonar as lightweight and fast, aimed at straightforward queries rather than multi-step deliberation. Its heavier siblings handle chain-of-thought reasoning. This one is tuned for speed and factual accuracy.
Search Depth You Control
Search context size can be set to low, medium, or high, controlling how much of the web is retrieved before answering. Results can be filtered by domain and by recency, from the past hour to the past year.
Cited Answers Writing
Every response carries inline citations pointing to its sources. That makes it strong for research summaries and fact-checking, and weak for creative or long-form writing, which is not what it was built for.
Live Web Search on Every Request
Sonar has no static knowledge ceiling because it searches before answering, every time. Perplexity reports it outperforms non-grounded models on factual question answering for exactly this reason.
Text and PDFs
Accepts text and PDF files, and can answer questions about a PDF's contents. It does not accept images, audio, or video as input.
