- Interactive Canvas: Offers an interactive "canvas" for refining writing and code.
- Enhanced Emotional Intelligence: Adapts better to user tone and context, providing more human-like responses.
- Creative Prowess: Unleashes enhanced creative capabilities, generating compelling stories and innovative ideas.
GPT-4.5 Access: Currently available to ChatGPT Pro subscribers ($200/month). Wider rollout planned. API access is significantly more expensive than previous models.
Let's proceed to the tasks!
Task 1: Image Interpretation
Prompt: "Determine the total number of triangles in this image."
Input Image:
Results: Both models failed to correctly identify the 18 triangles.
Verdict: Grok 3 ❌ | GPT-4.5 ❌
Task 2: Crafting a Welcome Email
Prompt: "Compose a welcome email for our new Head of Community and Principal AI Scientist, Dipanjan Sarka (LinkedIn: [LinkedIn Profile URL])."
Results: GPT-4.5 produced a more suitable welcome email for team-wide distribution. Grok 3's response felt more like a personal note.
Verdict: Grok 3 ❌ | GPT-4.5 ✅
