In breve:
Grok 4.5 è il nuovo modello di xAI, rilasciato mercoledì. Il prezzo via API è 2 dollari per milione di token in input e 6 in output, contro i 5/25 dollari di Opus 4.7 di Anthropic. xAI dichiara che il modello usa i token in modo due volte più efficiente rispetto ai predecessori, e Musk lo descrive come più veloce paragonandolo a Opus sia in costi che rapidità. Sui benchmark risulta competitivo con i modelli top, ma non il migliore in assoluto. Il rilascio arriva il giorno prima di GPT 5.6 di OpenAI, previsto per giovedì.

SpaceXAI releases Grok 4.5, which Elon describes as an 'Opus-class model' | TechCrunch
Elon Musk's tech company released the newest version of Grok on Wednesday, promising a cheaper, more efficient alternative to other powerful AI models., When it comes to achieving artificial general intelligence (AGI), large language models just don’t have what it takes. That gap, it turns out, might be filled by gaming data. That's the bet behind General Intuition, a Bezos-backed, New York-based startup valued at $2.3 billion that just closed a $320 million round with Coatue, Eric Schmidt, and researchers at MIT and Google DeepMind joining its list of investors. On this episode of TechCrunch's Equity podcast, General Intuition CEO Pim de Witte joins Rebecca Bellan to dig into why world models trained on gaming data might be the next big leap in physical AI, how the company spun out of gaming platform Medal TV, and where the ethical red lines are when your models could end up being used for defense applications.
