Perplexity has integrated its new GPT-4.5 model from OpenAI into its platform, granting Pro users access to its capabilities. With this feature, subscribers can use the enhanced abilities of GPT-4.5 for up to ten queries per day. The model is distinguished by improved natural language understanding and generation, an expanded knowledge base, and a reduced level of so-called AI “hallucinations.”

Available to all Pro users for up to 10 questions daily
GPT-4.5, which recently became available on the Perplexity platform, demonstrates a higher level of emotional intelligence and creativity. This makes it especially useful for tasks such as writing, problem-solving, and general communication. Offering the model to Pro users aligns with current trends of limited access to new models due to high computational resource demands.
OpenAI recently began rolling out the GPT-4.5 model to ChatGPT Plus users, starting on March 5, 2025. This process takes one to three days, and the query limits may change depending on demand. The model is the most resource-intensive ever developed by OpenAI and has significant operational costs, which has affected its availability via API.
Despite certain challenges, GPT-4.5 offers advantages such as deeper world knowledge, higher emotional intelligence, and a reduced frequency of erroneous results. The model has also demonstrated the ability to persuade other AI systems, especially in financial transactions. Initially available only to ChatGPT Pro plan subscribers, the model is gradually expanding to ChatGPT Plus users, allowing OpenAI to control its rollout and user interaction in real-world conditions.
