Great article! I've been trying to decide between Claude and GPT-4 for my project, and your breakdown of their strengths was incredibly helpful. I especially appreciated the section on context window comparisons.
I've been using multiple LLMs in my workflow for different tasks, exactly as you suggested. Using Claude for creative writing and GPT-4 for coding has been a game-changer for my productivity. Would love to see a follow-up article on how to create effective pipelines between different models!
Have you tested the code generation capabilities of these models with TypeScript specifically? I'm curious how they handle type definitions and generics. My experience has been mixed so far.
Great question, James! I've been exploring this exact topic for a follow-up article. In my testing, Claude 3 Opus and GPT-4 both handle TypeScript quite well, but they have different strengths. Claude tends to produce more maintainable type definitions for complex objects, while GPT-4 seems better with generics. I'll share more comprehensive findings in my next article!
