Claude Haiku 4.5 wins in 5 of 7 criteria analyzed. Check the full table to choose based on your use case.
Data is aggregated from Artificial Analysis (Intelligence Index, Coding Index) and Chatbot Arena/LMArena (ELO). Pricing and specs come from official APIs. Updated weekly.
The Intelligence Index is an aggregate score from Artificial Analysis that combines multiple academic benchmarks (MMLU, GPQA, LiveBench, etc.) into a single rating. The higher the score, the more capable the model is at reasoning tasks.
Yes. GPT-4o-mini costs $0.15/1M input tokens, while Claude Haiku 4.5 costs $1.25/1M tokens — 733% more expensive. For high-volume projects, GPT-4o-mini represents significant savings. Total cost also depends on output pricing and your application's usage pattern.
Claude Haiku 4.5 has the larger context window: 200K tokens vs 128K tokens. For long document analysis, extensive transcripts or full codebases, the larger context window is a decisive criterion.
