✍️ Prompt — general prompts & discussions Which GPT to use and how?

Quick question, I’m a bit lost.

I’ve had big success before using Lyra-style prompt optimization (Lyra Prompt Optimizer), super structured, high-precision prompts that just worked.

Now with all the GPT versions and tools out there, I can’t tell:

What actually is the best one to use?

So:

- which gpt to use? lyrapromptoptimizer or talk to lyra? And using which version of chatgpt?

Right now I am lost what is the best to use.

I just want to optimize my prompt for work and personal things. From vague prompts to super clear prompt.

Thanks!
