Anthropic Launches Claude Haiku 5.5, Cutting AI Costs by 75%

What happened: Anthropic released Claude Haiku 5.5, its most affordable and fastest AI model to date, on October 7. The new model offers a 1 million-token context window and costs just $0.10 per million input tokens—about 75% less than Haiku 4.5 for standard workloads. Benchmarks show Haiku 5.5 outperforming OpenAI’s GPT-6 Luna in several tasks, including OSWorld 2.1 (72.4% vs 48.9%) and Terminal-Bench 4.0 (39.2% vs 16.4%).

Why it matters: The aggressive price reduction intensifies the AI cost war, particularly for high-volume use cases like summarization and live support. However, the 75% savings headline applies only to prompts under 100,000 tokens; higher-context workloads see smaller benefits. Anthropic’s rapid release cadence—Haiku 5.5 follows Opus 5.5 and Sonnet 5.5 within weeks—signals a push for market share against OpenAI and other rivals.
