A controlled study evaluated eight expert-defined research projects in physics, astrophysics, and cosmology, comparing literature reviews performed by human experts against those by ChatGPT-4o, ChatGPT Deep Research, and Gemini. Human-AI reference overlap was below 6%, and 64% of AI-generated references had metadata errors (incorrect title, author, year, etc.), though only 3% were fully fabricated. A preliminary test of GPT-5.5 showed zero fabrications or metadata mismatches, suggesting significant improvement in the 2026 generation. The findings indicate mid-2025 models are complementary rather than substitutes for expert literature search, and require systematic verification.
OpenAI is rolling out improvements to the deep research feature in ChatGPT, including the ability to restrict research to specific websites and connected apps as trusted sources. Users can now create and edit a research plan before execution and adjust direction mid-run. UI changes include a redesigned sidebar and fullscreen report view. The update is rolling out to Plus and Pro users first, with Free and Go users to follow.
OpenAI has shipped improvements to the deep research feature in ChatGPT, adding the ability to restrict research to specific websites and connected apps as trusted sources. Users can now create and edit a research plan before execution and adjust direction mid-run. A redesigned UI with a fullscreen report view and sidebar entry point accompanies the update, with no changes to RBAC for Enterprise and Edu tiers.
OpenAI has launched 'deep research,' an agentic capability that uses reasoning to synthesize large volumes of online information and complete multi-step research tasks autonomously. The feature is initially available to ChatGPT Pro users, with rollout to Plus and Team tiers to follow. It represents a step toward practical autonomous research agents built on OpenAI's reasoning model infrastructure.
