Well, there is a retweet about Sophy being developed since 2016. That would be running on PS4. The problem is, will it run on its own? Meaning, the way Sophy runs now, it needs so much computing power that’s just no doable at the moment. As pointed out how Sophy may run, we won’t see it like the videos in this thread. It’ll be more as a learning/helping tool, than an outright competitor.
I think you are misunderstanding how neural networks work. The first part of it is training, which is what requires huge amounts of resources. What does it mean to do this training? It means running the Sophy agent on a computer connected to a console and then feeding those results back into the agent so it constantly improves its decisions with whatever heuristics it is making decisions based on. They talk about going from 4 playstations to hundreds or thousands of playstations in the cloud to do training of the network. That is the part that is not doable on your home console, simply because training a neural network requires hundreds of thousands of runs, which would take way too long to do on a single machine. Once the model is trained, they are straightforward to run - Sophy only makes 10 decisions per second, which is not very much at all. You can imagine that Sophy probably needs to be trained on a per track basis (so multiply those hundred of thousands of training runs by number of tracks), but that depends a lot on how they designed the network in the first place.
From what I understand, it won't learn anything near the rate it currnetly does (if at all) running on my PS4, but it should be able to run fine as an AI in a non-learning or low learning configuration. The raw computing power required during testing and development is primarily for testing and development.
So how our WT players were able to face this AI in a real race despite it being offline
2026 on Ps6
This question makes no sense. The World Tour event in Austria was LAN, using a dedicated game build, with dozens of high-performance PC servers to manage it. It wasn't an "offline" event using the public build of GT7 and 12 consoles connected to each other.
Oh, there was no misunderstanding. When you mentioned the PS4 bit, it reminded me of a retweet about the development since 2016. I just added what was already discussed about how Sophy was developed and unless someone has seen it currently operating on PS5, we Can only know how it’ll run by what we’ve being told(as a companion, etc.).
Is it not possible for GT Planet to arrange an interview so that we can find this information out? Thanks!
Pretty sure that is going to be a no. According to someone data mining the game Sophy is being implemented as a group of pre-defined missions. It is not coming to completely replace the current AI across the board.
PD haven't broadly talked about it since they conveniently promoted it just before GT7 released. We've seen the odd video direct from Sony AI, but nothing on the progress or when it's coming direct from PD.
No, it wasn't. The PS4 was running the Gran Turismo instance. The Sophy's were running on server hardware. If you read the paper that came out with the research it even tells you what it is. I've posted on this before in this thread.
If you've got evidence of Sophy actually running on PS4 rather than just giving commands to a PS4 that is running GTS/GT7 then please link it because I'd like to see it. But my understanding at this point is that they're still running the AI off server hardware and linking it into Playstations for the simulation environment.
We don't know, but given what we do know the bolded section is highly unlikely for GT7. Maybe GT8, but even then it's possible it would require more power than the PS5 has available to run that many instances of Sophy.
PD promised an extensive set of features and post-release support for GT6 that were in the end ultimately just lies to get people to buy a game that at launch was worse than the one they had spent two years building up from its own disastrous launch (alongside almost immediately announcing the server closure for that older, better game). For a couple of them Kaz went out of his way to specifically note they were going to come to the game as announced when people initially reacted with skepticism to the claims.
Chase the rabbit was originally a crutch to try and salvage GT5's framerate after launch. I suspect it just morphed into PD using it as a crutch so they don't actually have to put effort into designing a single player game; since GT5's AI, at least in comparison to GT6's and what I've seen of GTS', was fine.
It was said to only be some mission challenges and likely won't be implemented anywhere else.
So far it seems to be a technical exercise by Sony AI for use outside of gaming that also doubled as a way to promote GT7 and trick less knowledgeable people into thinking that was what the game would be. Instead they got the same old rubbish AI and catch the rabbit "racing".
If she's ever used ingame (likely she will not be) she's obviously not going to just be thrown in as is. That'd be asinine even by PD standards.
