[Enhancement]: support for Claude 3 models in GPT Pilot

[ShivamB25]

Version

VisualStudio Code extension

Suggestion

I would like to request adding support for Anthropic's latest Claude 3 model family, particularly Claude 3 Opus, to further enhance the AI development capabilities of the tool. Reasons for adding Claude 3 support:

1. Larger context window: Claude 3 offers an industry-leading 200K token context window, compared to GPT-4's 32K. This allows processing much larger codebases and repositories, enabling GPT Pilot to understand and generate code for more extensive projects.
2. Enhanced code quality: Based on user reports, Claude models tend to produce higher quality, bug-free code compared to GPT-3.5 or 4[6]. Claude 3's strong performance on coding benchmarks like HumanEval suggests it could help GPT Pilot write cleaner, more efficient code out of the box.
3. Improved instruction following: Claude 3 is known for its superior instruction following capabilities[12]. This could enable developers to provide more specific, nuanced instructions to GPT Pilot and get desired code outputs with fewer iterations.

I believe incorporating Claude 3, with its exceptional language understanding and generation capabilities, will unlock new possibilities for GPT Pilot and greatly benefit its developer community. Looking forward to this powerful upgrade to an already impressive tool!
