## Notes
- All solutions are self-contained and don't modify original course files
- SSL issues are handled for Windows environments
- Both OpenAI and Ollama integrations are included
- Solutions include proper error handling and user feedback
- Code is well-documented and follows best practices
## Next Steps
1. Complete remaining day solutions (Day 2, 4, 5)
2. Test all solutions thoroughly
3. Prepare for PR submission
4. Document any additional features or improvements

"\n",
"1. **What is Chat Completions API?**\n",

"Response: A Chat Completions API is a tool that allows developers to create applications that can interact with users through text-based conversations. Heres a simple breakdown:\n",
"\n",
"1. **Chat**: This means it can hold a conversation, similar to how you chat with friends or a customer service representative.\n",
"\n",
"2. **Completions**: This refers to the API's ability to generate responses. When a user sends a message or question, the API processes that input and provides a relevant response.\n",
"\n",
"3. **API (Application Programming Interface)**: This is a set of rules that allows different software programs to communicate with each other. In this case, it lets your application talk to the chat service to get responses.\n",
