I have been a big user of ChatGPT-4 ever since it came out. I have used in various forms. Through the chatbot, through GitHub Copilot etc. For the past year, I have looked high and low to see an alternative that performed better. Nothing came close. Until a few days ago with Anthropic released Claude 3. For software development work, it is very very impressive. I've been running GPT-4 and Claude 3 Opus side by side for a few days. And I have now decided to cancel all AI subscriptions except Claude 3.
For software development work, no other model comes close.
