• For local AI model workloads, NVIDIA GPUs with large VRAM are ideal. GPUs like the RTX 4090, RTX 4080, RTX 3090 or newer AI-specialized cards (like NVIDIA H100 series) are recommended if budget allows. Used RTX 3090 offers good value.[^2_6][^2_7]

1. If you get 404, but everything is ok, then check the order of routes. Because:

Route::get('/{userChat?}', [AiChatController::class, 'index'])->name('index');
Route::get('/create', [AiChatController::class, 'create'])->name('create');

1. Start always from clear plan, strategy. It should be step by step.

QA responsible for deploy on test envs, dev to provide changes itself

• If QA said that your changes not work in test env’s, check if it was successfully deployed (for example through Jenkins status).
• Then reproduce by yourself in test env
• Then go to deeper investigation.

Do not use inertia to fetch data. Instead please use axios or js fetch API. Because, when you do API request with inertia using useForm you should return back with message or return to route. You cannot return any usefull parameter ever never

Regression testing is a software testing process to ensure that code modifications, such as bug fixes or feature updates, haven't negatively impacted or broken previously functioning aspects of the software

 // Create a reflection of the private method to make it accessible for testing.
    $method = new ReflectionMethod(TransformDataForFrontend::class, 'removeUUIDsInString');
    $method->setAccessible(true);

 return $method->invoke((new TransformDataForFrontend), $sql);

While the terms are often used interchangeably, there is a technical distinction:

Publisher-subscriber is a network oriented architectural pattern and Observer is an object-event oriented pattern. They both are used at different Software levels.

Observer pattern: The subject (event) directly manages and notifies its observers (listeners). It's typically implemented within a single application process or codebase.

Pricing is the same as in AI providers API's\

1. OpenAI - Privacy . OpenAI temporarily stores your data for two main reasons, but it does not use your API data to train its models unless you explicitly agree to it.
   For Safety (Abuse Monitoring): OpenAI keeps a log of your requests (prompts and responses) for up to 30 days. This is like a temporary security camera recording. They use it to check if anyone is using the platform for harmful purposes, like creating illegal or dangerous content. This is the default setting for everyone.
   To Make Features Work (Application State): Some tools, like the Assistants API, need to remember your conversation history or the files you've uploaded to function correctly. If you create an Assistant, it will store that data until you decide to delete it. For most simple requests, like generating text with the Chat Completions endpoint, no data is stored for this purpose.
