How to Use
Pros
- Real-time information access through X/Twitter integration — no knowledge cutoff for current events
- Less restrictive content policies — handles topics other models refuse
- Strong reasoning — competitive benchmark scores with GPT-4o class models
- OpenAI-compatible API — easy to integrate into existing OpenAI-based applications
- Image understanding and generation capabilities
Cons
- Closed source — no model weights, training data, or architecture details
- Very limited third-party ecosystem — few integrations beyond X platform
- Heavily tied to X/Twitter ecosystem — less useful outside that context
- Shorter track record — less battle-tested than OpenAI or Anthropic models
- Not available on major cloud platforms (AWS, Azure, GCP)
- Less restrictive policies can lead to less safe outputs in some scenarios
