The best models in GPT-5, Gemini, and Claude are as follows:

For GPT-5, the best model is GPT-5 itself, which is the default for all ChatGPT tiers in 2025. It excels at knowledge-intensive, mission-critical tasks like drafting research papers, legal documents, full codebases, and enterprise automation. It offers top-tier reasoning and adaptability, surpassing prior models like GPT-4o and the legacy o3 model.​

For Gemini (Google AI), the best model currently is Gemini 2.5 Flash for price-performance balance and well-rounded capabilities suitable for large scale processing and low-latency requirements. However, the most advanced reasoning model is Gemini 2.5 Pro (in preview), designed for maximum accuracy and state-of-the-art tasks, though it may still be experimental.​

For Claude (Anthropic), the top model is Claude 3 Opus, noted for its intelligence and strong performance on highly complex, open-ended tasks. Another recommended default is Claude Sonnet, which is fast, accurate, and efficient across writing, research, and support use cases.

So I think, GPT-5 is good for you.
