Today, I conducted an in-depth trial of the two models, GPT-5 and Composer1, for project development. Below are my insights from comparing these two models.
Similarities
- They have the same price.
- Their level of intelligence is roughly the same.
Differences
Comparison Table: GPT-5 vs. Composer1
| Comparison Dimension | GPT-5 | Composer1 |
|---|---|---|
| Number of Mistakes | Makes fewer mistakes | Makes more mistakes |
| Detectability & Fixability of Mistakes | The mistakes made are hard to detect | The mistakes made are obvious and easy to fix |
| Running Speed | Is slower | Is faster, 4 to 10 times faster than GPT-5 |
| Running Stability | Sometimes freezes up | Rarely freezes up and runs more smoothly |
| When meet hard problem | Is willing to admit its own limitations | Prefers to take risks and give it a try |
