What is the best deep research model?

We're currently working on a product Focal AI that helps users dive deep into research on any topic. One of our core features is called "Deep Research", and we're now at a key decision point: choosing the right AI model to power it.

After testing many of the current top-tier LLMs, we've found that most can handle broad, high-quality research prompts. But the results still vary a lot depending on:

• The specific model

• The domain of research

• The depth of exploration required

We'd love to hear from you:

💬 What model do YOU use for deep research? 🛠️ How do you use it? 🎯 What use case or field are you focused on (e.g. academic, technical, market analysis, etc.)?

Thanks in advance for helping us make better decisions – your feedback means a lot! 🙏
