Detailed Breakdown by Category

Best for Coding: Claude Opus 4.5

Claude Opus 4.5 edges out GPT-5.2 for coding tasks with a 9.7 vs 9.5 score. In our testing, Claude demonstrated superior understanding of complex codebases, better refactoring suggestions, and more accurate bug detection. It's particularly strong at understanding context across large files.

Runner-up: GPT-5.2 excels at algorithm design and has better performance on competitive programming-style problems.

Best Value: Gemini 3 Flash

At just $0.075 per million input tokens, Gemini 3 Flash offers an incredible 85% cost reduction compared to GPT-5.2 while still achieving an 8.5/10 overall score. For high-volume applications, this translates to thousands of dollars in monthly savings.

When to upgrade: If you need complex reasoning (score 9.5+) or the highest accuracy on critical tasks, consider GPT-5.2 or Claude Opus 4.5.

Best for Long Documents: Gemini 3 Pro

Gemini 3 Pro's 2 million token context window is unmatched. You can process entire books, lengthy legal documents, or massive codebases in a single request. Combined with strong factual accuracy (9.5), it's ideal for research and document processing.

Best Open Source: Llama 3.3 70B

For teams requiring self-hosted solutions for privacy, compliance, or cost optimization at scale, Llama 3.3 70B is the clear choice. While it trails frontier models in capability (8.3/10), it's free to use and can be fine-tuned for specific domains.
