9.2. Problem 1
The question:
 |
The answer from DeepSeek leaves something to be desired. It is less precise than those generated by the other IA.
9.3. Problem 2
The question:
 |
The first answer is incorrect. Let’s try again:
 |
The next answer is a little better:
 |
The next response is very disappointing. Almost all tests fail. In the responses from DeepSeek, we don’t sense the certainty of the first IA models tested. It seems that IA doubts the accuracy of its own answers. Furthermore, it seems like DeepSeek isn’t thinking. It gives an answer very quickly, whereas ChatGPT took minutes to think. Perhaps a configuration issue.
 |  |
This time it’s better. There’s only one failure left, off by 2 euros. Other IA instances failed this same test with the same 2-euro discrepancy. We’ll consider DeepSeek’s script to be correct.
9.4. Problem 3
The question
 |
This time, no more PDF. DeepSeek will have to look up the calculation rules online.
First result: all 25 tests fail. Let’s try again.
 |
All 25 tests fail again.
 |
Once again, 25 tests failed. We give up and conclude that DeepSeek was unable to solve Problem 3 within a reasonable amount of time.
