💡 Pro Tips From Our Testing
-
💡 Combo strategy works best: Use ChatGPT for speed/creativity, Claude for code reviews, Gemini for research. All three offer free tiers — test workflows before paying.
-
💡 Context window math: Claude’s 200K tokens ≈ 150,000 words. GPT-4’s 128K ≈ 96,000 words. In practice, both handle any realistic document. Gemini’s 1M is marketing — you’ll never need it.
-
💡 Hallucination check: Always verify factual claims, especially dates, statistics, and technical specifications. Cross-reference with a second AI or Google. Claude is most reliable but still hits 8% error rate.
-
💡 Custom instructions matter: Spend 10 minutes setting these up in ChatGPT (e.g., “I’m a Python dev, be concise, show code examples”). It dramatically improves output quality. Claude and Gemini lack this feature.
-
💡 API arbitrage: If you’re building on these models, use Claude’s API — it’s 3x cheaper than GPT-4 and often better for structured outputs. Reserve GPT-4 for user-facing chat where speed matters.
❓ FAQ
Is ChatGPT-4 worth $20/month in 2026?
Yes, if you use it daily for work. The speed, plugins, and polish justify the cost for professionals. If you’re casual, stick with the free tiers — ChatGPT-3.5 and Claude 3.5 Haiku are both surprisingly capable.
