o3 Model to debug code, solve math and read charts
OpenAI Chat and reasoning models Upgrade to use openai/o3
This page describes the OpenAI o3 model and who chooses it. o3 is a reasoning-focused model suited for multi-step code debugging, advanced math, and visual document analysis, available side-by-side with other models on Katteb Chat.
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
Debug a production bug and get testable patches
Give o3 your repository snippet and failing test output; it traces the error, proposes a fix, and explains why the patch should pass. The concrete outcome is a ready Git patch or diff and a short test plan you can run.
Solve complex math or engineering problems
Upload the problem statement and any data files; o3 works step by step to show derivations, numeric checks, and final results. The outcome is a checked solution with intermediate steps you can verify.
Extract numbers and insights from images and PDFs
Drop invoices, charts, or screenshots and ask o3 to read values, compute totals, or summarize trends across pages. The outcome is a table of extracted fields and a short, verifiable summary.
Why it is worth it
- Reasoning traces that explain how the answer was reached, not just the final line.
- Handles mixed inputs: text, code, images and uploaded files in one request.
- Switch models mid-conversation on Katteb to compare answers without losing context.
- Billed per message in Katteb credits so cost scales with actual usage.
Questions people ask
What is o3 best suited for?
OpenAI o3 is built for step-by-step reasoning across coding, mathematics, science and visual inputs. Use it when you need multi-step analysis, code explanation or chart and image interpretation.
How does Katteb charge for using o3?
Katteb bills per message based on actual usage in credits; o3 messages cost 19 credits each in Katteb. You only pay for the messages you send and receive during the chat.
Can o3 use files, images or web data?
Yes. o3 supports visual reasoning and can analyze uploaded files and web search results when those tool integrations are available, so you can combine text, code and images in the same query.
