Deep dive
The capability footprint differs most on function calling: Claude Haiku 4.5, tool use: Claude Haiku 4.5, and structured outputs: Claude Haiku 4.5. Both models share vision, multimodal input, and code execution, 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 Haiku 4.5 lists $0.80/1M input and $4/1M 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 Haiku 4.5 lower by about $17.24 per million blended tokens. Availability is 8 providers versus 1, so concentration risk also matters.
Choose Claude Haiku 4.5 when coding workflow support, larger context windows, and lower input-token cost are central to the workload. Choose GPT-4 Vision Preview when coding workflow support 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.
