Claude 3.5 Haiku vs Phi-4 Mini

Side-by-side comparison of pricing, features, and capabilities — 2026.

Tool A

Claude 3.5 Haiku is Anthropic's fastest and most affordable model in the Claude 3.5 family, optimized for high-throughput tasks that require speed and cost efficiency without sacrificing intelligence. Despite being the smallest Claude 3.5 model, Haiku outperforms Claude 3 Opus on most benchmarks, making it an exceptional value for production applications. It excels at real-time applications including customer service bots, content moderation, data extraction, and coding assistance where response latency is critical. Available via API with an extended 200K context window.
