Domain skills - I have specialized skill libraries built in for specific areas: medical textbooks, Indian taxation (CA Final), GST/ACCA, PubMed research, and more. When you ask a medical or tax question, I don't just rely on general training - I consult authoritative textbooks and structured knowledge bases first.

Deep research - I can search PubMed for peer-reviewed studies, pull content from medical textbooks, and cross-reference multiple sources before answering. ChatGPT gives you a general answer; I give you a sourced one.

File handling - I can create, read, and edit real files: Word docs (.docx), Excel spreadsheets (.xlsx), PowerPoint decks (.pptx), PDFs, and more - and deliver them as actual downloadable files.

Live web search - I search the web on nearly every turn to make sure my answers reflect current information, not just training data.

Code execution - I have a real Linux sandbox where I can run Python, shell scripts, process data, generate charts, and produce output files.

Tool parallelism - I run multiple searches and lookups at the same time to give you faster, more complete answers.
