GPT 5.2 Update Highlights

In a compelling video titled “GPT 5.2 is here.. the biggest update yet?” published on December 11, 2025, the YouTube channel Prompt Engineering delves into the details of OpenAI’s latest GPT-5.2 update. The video boasts an impressive 11,998 views and engages the audience with insights into this major advancement in AI, which purportedly surpasses competitors like Gemini 3 Pro in several performance benchmarks.

The narrator kicks off the video by highlighting GPT-5.2’s superior benchmark performance, proclaiming its ability to beat Gemini 3 Pro and regain the lead for OpenAI, hinting at a significant development in the landscape of artificial intelligence. Impressively, GPT-5.2 introduces new features like native image output support and maintains high performance as the number of tokens increases—a stark improvement over its predecessors. This positions GPT-5.2 not just as an enhancement, but a leap forward in AI capabilities, marking it as a potential frontrunner in the AI race.

However, the video doesn’t shy away from critiquing the model’s shortcomings. While GPT-5.2 commands a second place in the high-setting of the webdev arena leaderboard, it falls to sixth place at the normal setting, lagging behind OPUS 4.5. This highlights an area for improvement and suggests that while newly introduced features are substantial, they do not yet comprehensively outpace all competitors on every front.

Furthermore, the video points to discrepancies in cost-effectiveness, as GPT-5.2 is said to be pricier than preceding versions, limiting its application to more professional and economically significant tasks. Here, one may wonder about the balance between cost and utility in AI advancements.

Nevertheless, the reduced hallucination rate in GPT-5.2 is a noteworthy improvement, decreasing from 8.8% to 6.2%, representing a 30% reduction—a significant achievement illustrating OpenAI’s commitment to refining model accuracy. The enhanced capability to handle longer contexts and improved vision model performance emphasize new benchmarks in computational achievements, although the video notes that such results must be corroborated with real-world data.

Prompt Engineering’s video closes inviting viewers to anticipate more extensive testing and real-world examination of GPT-5.2, underscoring the continued journey of AI evolution. The engagement with GPT-5.2 exemplifies the growing complexity and nuance of AI development, emphasizing the need for careful evaluation as these systems become more integrated into everyday life.
