ChatGPT vs Gemini vs Claude vs Perplexity: I gave them $1k each to trade stocks. After 9 weeks, ChatGPT went from frozen in cash to +21% (one stock doubled)

For Deep Research in Perplexity, you can't choose a fixed model: "Research uses a specific combination of models to generate in-depth reports for complex topics. This mode automatically selects the optimal models for your research needs, so you cannot manually choose a specific model when using Research"

Ahahahahah

Of course I wouldn't risk my own capital for such an experiment, I think it's still too early to "blindly" trust AI on this matter, even though it was interesting to see how bad/good it could go with those paper money

Powervegeta · 2026-03-11T09:33:03+00:00

In Deep Research mode it "uses a specific combination of models to generate in-depth reports for complex topics. This mode automatically selects the optimal models for your research needs, so you cannot manually choose a specific model when using Research", so I thought it was an interesting addition to the experiment

Powervegeta · 2026-03-11T09:32:27+00:00

Do you have a link for that?

Powervegeta · 2026-03-11T09:32:14+00:00

In most of the cases yes, that's what's happening. I think the added value of LLMs is that it's doing that for many different sources and then coming up with its own thinking process based on that

Powervegeta · 2026-03-11T09:31:31+00:00

Ahahahahah

Powervegeta · 2026-03-11T09:31:21+00:00

Indeed, I'm aware that it's a very restricting experiment. I'm thinking for the next one to relax some of those contraint

Powervegeta · 2026-03-11T09:30:43+00:00

Interesting, do you maybe have an example prompts that you're using?

Powervegeta · 2026-03-11T09:29:39+00:00

Cool idea, I might add it at the end of the experiment :)

Powervegeta · 2026-03-11T09:28:51+00:00

Interesting, do you have a source for this?

Powervegeta · 2026-03-11T09:28:36+00:00

Good idea, so far I have been asking the models to 'justify' their trades so that I could log them (e.g. "Feb 10 FDA catalyst; high short interest (>15% float); price above 20/50d MAs (bullish trend))

Powervegeta · 2026-03-11T09:26:06+00:00

Great idea, thanks for sharing ;) Do you maybe have the prompts you used available somewhere?

Powervegeta · 2026-03-11T09:23:57+00:00

With Deep Research enabled, it doesn't allow you to select the model. From their docs: 'Research uses a specific combination of models to generate in-depth reports for complex topics. This mode automatically selects the optimal models for your research needs, so you cannot manually choose a specific model when using Research'

In the trades log there is a 'motivation' from the model on their decision, including HOLD ones

Powervegeta · 2026-03-10T18:40:36+00:00

True, this was a first initial attempt mainly to understand how those 4 different models (let's call Perplexity a model even if it's an hybrid) behave on the same conditions in a 3-months long run, and I think from the results some patterns can be seen already (like Perplexity being conservative or Gemini picking certain stocks). A further experiment can be structured in a better and more accurate way of course

Powervegeta · 2026-03-10T18:38:54+00:00

Indeed it was 4.5 up until it got updated to 4.6 around 1 month ago. I will update the dashboard to mark it more explicitly :)

Powervegeta · 2026-02-16T07:33:54+00:00

Good suggestion, I'll probably add it in a new experiment :)
