💭 Reddit User Sentiment
Positive Comments
"Throwing a 1-million-token codebase at it is instant. And dirt cheap. I can't let it go."
"Agentic Vision is amazing. Just paste a screenshot and it writes perfect code and validates it itself."
Negative Comments
"It sometimes lies with extreme confidence (hallucination), so blind trust is dangerous."
"If you ask it to write a novel, it's flatter than Pro. Not suitable for creative uses."
🎯 Recommended Use Cases
