Head-to-head · Updated March 2026
Both Claude 4 Haiku and GPT-5.2 Mini are built for high-volume, low-cost workflows. Claude 4 Haiku wins on writing tone and output quality — it's the budget pick when what you're generating actually gets read. GPT-5.2 Mini wins on price and breadth of use cases. For writing-heavy automations, Haiku is the better pick. For general-purpose cheap inference, GPT Mini competes well.
Claude 4 Haiku
Best low-cost writing option for fast-moving content teams.
WinnerGPT-5.2 Mini
Solid OpenAI budget option, though Gemini Flash offers better value.
| Claude 4 Haiku | GPT-5.2 Mini | |
|---|---|---|
| Input cost / 1M tokens | $$0.80/1M | $$1.20/1M |
| Output cost / 1M tokens | $$4.00/1M | $$4.80/1M |

| Price tier | Budget | Balanced |
Which model wins for each use case — and why.
Claude 4 Haiku produces more natural, polished output for writing tasks — captions, emails, short-form copy. Anthropic's training advantage shows most clearly in budget writing quality.
GPT-5.2 Mini is slightly cheaper than Claude 4 Haiku. For extremely high-volume pipelines where every fraction of a cent matters, Mini has the edge.
Both models are in the 'Very fast' tier. Response latency is comparable — neither has a meaningful advantage for most applications.
GPT-5.2 Mini handles light coding tasks slightly better than Claude 4 Haiku. Neither is a strong choice for serious coding — upgrade to Claude Sonnet 4.6 or GPT-5.4 for that.
GPT-5.2 Mini covers a broader range of use cases reliably. Claude 4 Haiku is more narrowly optimized for writing-first tasks.
