Deep dive
The capability footprint differs most on vision: GPT-4 Vision Preview, multimodal input: GPT-4 Vision Preview, structured outputs: Claude Instant 1.2, and code execution: GPT-4 Vision Preview. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Claude Instant 1.2 lists $0.80/1M input and $2.40/1M output tokens on the cheapest tracked provider, while GPT-4 Vision Preview lists $10/1M input and $40/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Claude Instant 1.2 lower by about $17.72 per million blended tokens. Availability is 2 providers versus 1, so concentration risk also matters.
Choose Claude Instant 1.2 when provider fit, lower input-token cost, and broader provider choice are central to the workload. Choose GPT-4 Vision Preview when coding workflow support and larger context windows are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions.
