GPT-4o Mini vs Claude 3 Haiku: The Race to the Bottom
2026-04-05Knowledge Base
While flagship models grab the headlines, the real enterprise workhorses are the "small" models. OpenAI's GPT-4o Mini and Anthropic's Claude 3 Haiku offer blistering speeds at a fraction of the cost.
The Pricing War
Both models have driven the cost of intelligence near zero:
- Input Costs: Often hovering around $0.15 to $0.25 per 1 Million tokens.
- Output Costs: Usually under $1.25 per 1 Million tokens.
At these rates, processing the entire text of the Harry Potter series costs pennies.
Multimodal Capabilities
The true differentiator is vision. Both models support image inputs, making them incredible tools for:
- Receipt scanning and OCR.
- Basic image categorization.
- UI component analysis.
Because their base image token costs are so low, they are the ideal first step in a routing architecture. If Haiku fails to understand an image, only then escalate the request to the expensive Claude 3.5 Sonnet.
