Our pick

For most workloads, choose DeepSeek V3.5.

  • 86% cheaper input price, which compounds at scale

Roughly GPT-4o-class quality at roughly 90% off. Tradeoff is region availability (Chinese provider) and slower output throughput than Western frontier tiers.

Choose Claude Haiku 4.5 instead if: Anthropic’s economy tier — gentler tone, stronger safety patterns than mainstream tiny models. Choose when output voice matters more than raw IQ.
