Finalmente um salto real? A GPT-4.5 parece impressionante nas especs, mas só vou acreditar quando testar a tal 'contextualização multimodal'. Todo anúncio fala em 'inovação', mas a diferença real no uso diário? O preço também vai ditar quem realmente vai usar... 🤔

Looks like OpenAI is still the king of the game 😅 The rumored pricing structure for GPT-4.5 is interesting – will it push more devs towards open-source models? Let's hope the 'competitive edge' isn't just about locking users in.

Wow, they're already teasing GPT-4.5? The release pace is insane! My main thought: how are smaller companies supposed to stay competitive? The pricing will be the real deciding factor. Also... should we be worried about how quickly these models are evolving? 🤔 The power is incredible, but the responsibilities seem immense.
