ChatGPT 4o — The Swiss army knife
ChatGPT remains the go-to general-purpose AI in 2026. Its ecosystem of custom GPTs and compatibility with hundreds of third-party tools makes it unbeatable in versatility.
What we loved: integrated image generation via DALL-E 3 is impressive, real-time web browsing works well, and specialized GPTs let you create custom assistants in minutes.
What we liked less: on long-form nuanced writing tasks, ChatGPT tends to be verbose and hallucinate on recent facts. The 128k token window is starting to show its limits compared to Claude.
Best for: generating images, coding with plugin assistance, using specialized GPTs, browsing the web.
Claude 3.5 Sonnet — The writing champion
Claude clearly stands out as the best writing and analysis tool right now. Its 200k token context window lets you ingest entire documents without losing the thread, and the quality of generated text is a notch above.
What we loved: complex instructions are followed more accurately, texts feel more natural and less "AI-generated," hallucinations are rare. The 200k context window is a game changer for analyzing large PDFs.
What we liked less: no image generation, smaller integration ecosystem than ChatGPT, and the free tier is more restrictive.
Best for: long-form writing, document analysis, complex coding, tasks requiring maximum precision.
Gemini Ultra — The Google integration ace
Gemini surprises with its 1 million token context window — by far the largest on the market. Its native integration with Google Workspace (Docs, Drive, Gmail, Sheets) makes it the ideal tool for teams already in the Google ecosystem.
What we loved: the massive context allows analyzing entire books, Google integration is seamless, and the free tier is the most generous of the three.
What we liked less: creative task performance still lags behind, and the interface is less polished than competitors.
Best for: analyzing very large documents, working in Google Workspace, free daily use.
Our final verdict
There's no universal "best" LLM — it all depends on your use case:
- For writing and analysis → Claude, no hesitation
- For code and versatility → ChatGPT
- For large documents and Google Workspace → Gemini
- To start for free → Gemini (most generous free tier)
