OpenAI has announced the release of GPT-5.3 Instant, the latest iteration in its GPT-5.3 series. This model aims to enhance user interaction by being less prone to moralizing and overly cautious responses, particularly regarding sensitive topics.
In a recent blog post, OpenAI acknowledged feedback regarding its predecessor, GPT-5.2 Instant, which sometimes declined to answer questions that it could address safely, leading to frustration among users. The company emphasized that the new model is designed to provide direct answers without unnecessary caveats, thereby improving the overall conversational experience.
Adjustments to Defense Department Deal
In a related development, OpenAI has made headlines for its partnership with the U.S. Department of Defense (DoD). Following a controversial decision by rival Anthropic to reject a similar deal, OpenAI’s CEO, Sam Altman, announced plans to amend the contract to prohibit tracking and surveillance of U.S. citizens. Altman expressed regret for the timing of the deal, suggesting that it may have appeared opportunistic.
Improvements in Accuracy and Contextualization
OpenAI claims that GPT-5.3 Instant significantly reduces the rate of hallucinations—instances where the model generates incorrect information. Evaluations indicated a reduction in hallucination rates by 26.8 percent when using web data and 19.7 percent when relying solely on internal knowledge, compared to earlier models. Additionally, user feedback showed a 22.5 percent decrease in hallucinations with web access.
The model is also reported to perform better at contextualizing information during web searches, enhancing its utility in various applications.
Performance Metrics and Availability
Despite these advancements, GPT-5.3 Instant has shown some regressions in specific areas compared to its predecessors, particularly concerning disallowed content evaluations. OpenAI noted that while the model performs better in many categories, it has regressed in handling certain sensitive topics, though these regressions are statistically insignificant.
Users can start utilizing GPT-5.3 Instant immediately, while GPT-5.2 Instant will remain accessible to paid users until June 3, 2026.
