- ✦ Artifacts feature
- ✦ Computer use (beta)
- ✦ Open source
- ✦ Chain-of-thought reasoning
- ✦ Math solving
Real-World Scenarios: When to Choose Which
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Artifacts generates executable notebooks and SQL queries that render directly. Analyses iterate 3x faster with real-time output updates - no Jupyter or IDE context switch.
Multimodal feature parses documents containing tables and images within internal wiki. Liability clauses and compliance gaps extract with visual context - no separate image-to-text.
200K context loads entire codebases to identify cross-file vulnerabilities. No chunking - audit cycles compress from weeks to days with ~45% fewer false positives.
Computer use (beta) handles form-filling, screenshot validation, and cross-browser testing. Test setup time drops ~60%; dynamic UI elements that static selectors miss are handled.
Chain-of-thought reasoning solves multi-step financial models in spreadsheet via API. Open-source architecture lets compliance teams audit exactly how each answer was reached.
Run on local infrastructure for high-volume APIs. At $0.14/million tokens versus $15 for LLM, startups process millions of queries monthly without vendor lock-in.
