How to Use
Pros
- Much cheaper than o3 — accessible reasoning at a fraction of the cost
- Good reasoning performance for the price — handles most logic and math tasks well
- Faster than full o3 — shorter reasoning chains mean quicker responses
- Available on ChatGPT Plus ($20/mo) — no need for the expensive Pro subscription
Cons
- Weaker than o3 on the hardest competition-grade problems
- Still slower than non-reasoning models due to chain-of-thought overhead
- Closed source — no visibility into model internals
- No vision support — text-only input
What to Use It For
Perfect For
Brings chain-of-thought reasoning at a fraction of o3 cost — ideal for moderate complexity logic
Strong enough for most STEM tasks without paying for full o3 capabilities
Chain-of-thought helps trace through bugs and design patterns at reasonable cost
Good For
Reasoning steps help methodically trace through error chains
Not Recommended
Reasoning depth is insufficient for olympiad-level problems — needs full o3
Try instead: o3
Reasoning overhead adds unnecessary latency and cost for straightforward queries
Try instead: GPT-4o Mini
Do Not Use For
Chain-of-thought reasoning makes response times too slow for interactive UIs
Try instead: GPT-4o
No vision capabilities — text only
Try instead: GPT-4o
