From an investment standpoint:

1. The technology behind it is in the open, and relatively simple ( the models are well understood, and easy to define ) To replicate that ... (with proper engineering etc a good and small team would probably need 1-3 months ) (The model itself could be built in a day )

2. Training: Here comes the biggie, training the above model on lots and lots of data is what gives it its quality. This is the bulk of time and cost, and also why smaller companies have a hard time replicating this. We are talking trainings costs in the 9 figures.

But 2 does not really matter to those giants tech companies, just smaller competitiors.

I would estimate depending on the desired outcome 3-6 months to replicate ChatGPT for those companies.
