Detailed Review
ChatGPT launched on November 30, 2022, and set a historical record by reaching 1 million users in just 5 days — faster than any consumer product ever created. OpenAI was co-founded by Elon Musk and Sam Altman in 2015 as a non-profit with the mission of developing safe AI for humanity, before transitioning to a "capped-profit" model to attract investment.
GPT-4o — the current foundation model — is a significant leap forward in multimodal capability. It doesn't just read text; it can analyze images, charts, code screenshots, and even emotional tones in speech. Advanced Voice Mode enables real-time conversation with the AI at under 1 second latency, recognizing emotional nuance and responding with remarkably natural speech.
Custom GPTs is a game-changing feature — anyone can create a specialized version of ChatGPT for their own work without writing a single line of code. From GPTs that help write dissertations to ones that analyze financial reports, millions of custom GPTs have been created by the community. The Memory feature lets ChatGPT remember your preferences and context across conversations, making every interaction more personalized over time.
Current Developments (2025–2026)
In 2025–2026, OpenAI has been releasing new models at a breathtaking pace. OpenAI o3 and o4, with "extended thinking" capability, allow the AI to deliberate longer before answering — particularly excelling in mathematics and science. GPT-4.5 improves "social intelligence," understanding emotions and communicating more naturally. Projects like Sora (video generation) and ChatGPT Search are directly challenging Google. OpenAI's latest funding round values the company at $300 billion USD.
Strengths
- GPT-4o simultaneously handles text, images, audio, and code in the same conversation
- Code Interpreter runs real Python, analyzes data, and draws charts without copying to another tool
- Memory retains information about you across sessions — the experience grows more personalized over time
- GPT Store with millions of custom GPTs specialized for every profession and field
Areas for Improvement
- Occasionally hallucinates information or cites sources incorrectly — always verify when used for important work
- Plus plan at $20/month is fairly expensive; the free tier noticeably limits daily GPT-4o usage
- Cannot read URLs or files directly from personal cloud storage without uploading them first
