Every week someone asks us "which AI should I use?" The answer depends entirely on what you're trying to do. Here's the real breakdown as of April 2026.

Claude by Anthropic currently sits at Opus 4.7 — dominating in coding performance, long-document analysis, and technical precision. On CursorBench, Opus 4.7 scored 70% versus Opus 4.6's 58%. If you're building software, writing technical documentation, or running agentic workflows, Claude is the move. It also has the strongest instruction-following of any model tested, and Claude Code's Routines feature lets you schedule agents that run 24/7 without your laptop being open.

"ChatGPT by OpenAI is now at GPT-5.5 — their smartest model ever."

ChatGPT by OpenAI is now at GPT-5.5 — their smartest model ever. It beats everything on Terminal-Bench 2.0 at 82.7% and sets records in knowledge work. It excels at agentic coding, computer use, and research workflows. Matches GPT-5.4 speed while being significantly more intelligent, using fewer tokens to complete the same tasks. If you do broad knowledge work — finance, law, content strategy, research — GPT-5.5 is a beast.

Gemini 3.1 Pro by Google leads in multi-task reasoning and has the deepest integration with the Google ecosystem. If your workflow lives in Google Docs, Sheets, Gmail, and Search — Gemini is seamless.

The MentorMe approach: use multiple models for different tasks. Claude for building and coding. ChatGPT for research and broad knowledge work. Gemini for anything Google-ecosystem. That's the 80/20.

Action step: Pick one task you do daily and run it through all three models this week.
