The platform is powered by GPT-3.5 and GPT4 32K, allowing its AI to provide real-time results based on real-time information provided by Google.
On March 11, 2026, Writesonic’s analysis revealed that ChatGPT’s default (GPT-5.3 Instant) and premium (GPT-5.4 Thinking) models cited almost entirely different sources when responding to the same questions. The analysis found that the premium GPT-5.4 Thinking model directed 56% of its citations to brand websites, while the default GPT-5.3 Instant sent only 8%. This analysis followed Writesonic's earlier testing on March 8, which involved 50 prompts across both models, to understand how they searched the web and cited sources after ChatGPT rolled out GPT-5.3 Instant as its new default and GPT-5.4 Thinking as its new premium offering. Previously, on March 7, 2026, a review of Writesonic highlighted its AI Article Writer 6.0 and Chatsonic’s real-time research capabilities, while noting a limitation in its no-rollover credits system. These developments occur as Writesonic tracks how AI models describe brands across over 500 million conversations, following OpenAI’s replacement of GPT-5.2 with GPT-5.4 as the default model in ChatGPT on March 5, 2026, with GPT-5.2 Thinking set for complete retirement by June 5, 2026.
