Claude Haiku 4.5 vs GPT-5.4 mini: Which Should You Choose?
Choosing between Claude Haiku 4.5 and GPT-5.4 mini depends on your priorities: cost efficiency, context length, or raw capability. GPT-5.4 mini is the more affordable option at $0.75/1M input tokens — 25% cheaper than Claude Haiku 4.5. Meanwhile, GPT-5.4 mini offers a significantly larger context window at 1,050,000 tokens vs 200,000 for Claude Haiku 4.5.
These models come from different providers — Anthropic and OpenAI — which means different API ecosystems, SDKs, rate limits, and terms of service. If you're already integrated with Anthropic, switching to OpenAIinvolves migration effort beyond just pricing. Factor in your existing infrastructure when deciding.
Both models are in the efficient category, making this a direct head-to-head comparison. At scale — say 10,000 requests per day — the cost difference adds up: GPT-5.4 mini would save you roughly $150.00/month compared to Claude Haiku 4.5. For startups and indie developers, that difference can be significant.
Output costs matter too. Claude Haiku 4.5 charges $5.00/1M output tokens vs $4.50 for GPT-5.4 mini. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. GPT-5.4 mini has the edge here at $4.50/1M output tokens.
Multimodal capabilities: Both models support vision (image understanding), so you can send images alongside text prompts with either option.
Best Use Cases
