Claude Haiku 5.5 and GPT-6 Luna share price, but Haiku costs 12x more over 100k tokens

Anthropic's Claude Haiku 5.5 and OpenAI's GPT-6 Luna are priced identically at $0.10 per 100,000 tokens. However, a critical difference emerges with context window usage: Claude Haiku 5.5's API price quintuples after 100,000 tokens, making it significantly more expensive for tasks exceeding this limit. In contrast, GPT-6 Luna's price increase occurs at a much higher 272,000 token context, and it automatically compacts at this limit. This pricing structure means Claude Haiku 5.5 can cost up to 12 times more than GPT-6 Luna for certain operations, such as processing a "voxel pagoda" test case. AI

IMPACT The pricing model of Claude Haiku 5.5 over 100k tokens could significantly impact its adoption in agentic workflows compared to GPT-6 Luna.
