Grok 4.20 Multi-Agent AI Model to analyze codebases, reviews and invoices
xAI Chat and reasoning models Upgrade to use x-ai/grok-4.20-multi-agent
This model runs several Grok agents in parallel to research, cross-check and synthesize long, complex inputs; it includes vision, file and web tools and a 2 million token context window. It is for teams that need a single query to cover entire codebases, legal or financial archives and multi-document research.
What it can do
- Reads images and screenshots
- Searches the live web and cites sources
- Reads PDFs and documents
- Thinks step by step on hard questions
What people use it for
Audit an ad spend history across months
Send multi-year CSVs and receipts; agents split the work to extract transactions, flag outliers and produce a reconciled expenses table with line-item references and source files. Use the built-in web and files tools for live rate checks and invoice parsing.
Review and explain a large codebase
Point the model at a repository or upload the code archive: parallel agents summarize modules, highlight security risks, and produce runnable examples and a prioritized TODO list. The 2 million token context lets the model treat the repo as one input rather than fragmented prompts.
Research and verify multi-source reports
Ask Grok to gather sources, cross-check contradictions and output a single annotated brief with citations and extracted quotes. Agents can use xAI web tools and internal debaters to reduce single-agent blind spots on broad research questions.
Why it is worth it
- Process entire multi-year document sets in one request using a 2 million token context.
- Parallel agent roles: search, verify, reason and synthesize to surface conflicting evidence.
- Built-in vision and file handling so images, PDFs and spreadsheets can be included in the same query.
- Switch models or agent settings mid-conversation inside Katteb Chat without opening a new account.
Questions people ask
What is Grok 4.20 Multi-Agent best for?
It is best for long-context, multi-step work where separate reviewers or tools would normally be required: whole codebases, multi-year financial records, legal archives and broad research briefs. The multi-agent architecture and 2 million token window let you ask one question against everything at once.
How do I pay for Grok 4.20 Multi-Agent on Katteb?
Katteb bills per message in credits. This Grok variant costs 7 credits per message; actual billing shows on your Katteb account and charges against credits used for each model message. Do not expect per-message dollar prices on this page.
Can the model use my files, images and the web in one request?
Yes. The multi-agent variant supports vision, file uploads and server-side web tools so agents can parse PDFs, spreadsheets and images and fetch online sources during the same session. Enable the relevant built-in tools when you call the model.
