Anthropic's Claude Haiku 4.5: GPT-5 Performance at Warp Speed, Lower Cost

The artificial intelligence race just got a whole lot faster and cheaper. Anthropic has unveiled Claude Haiku 4.5, a new model that matches the smarts of OpenAI's GPT-5 but with significantly greater speed and efficiency.

Speed and Efficiency Take Center Stage

Anthropic says Haiku 4.5 delivers performance that was recently considered cutting-edge. The model balances speed, cost, and intelligence. Its architecture is optimized for quick-response scenarios like customer service and real-time Q&A.

Outperforming Giants

Benchmark tests back up Anthropic’s claims. On the SWE-Bench coding accuracy test, Haiku 4.5 scored 73.3 percent, exceeding GPT-5's 72.8 percent. It also tied Google's Gemini 2.5 on the Terminal-Bench command-line reasoning test.

A Multi-Agent Approach

Mike Krieger, Anthropic’s Chief Product Officer, emphasized the model's speed and accuracy parity with GPT-5. He also noted that multiple instances of Haiku can work in parallel. This allows for complex task division within the broader Sonnet 4.5 system.

A $7 Billion Projection

Anthropic's annual revenue is projected to hit $7 billion this year. Haiku 4.5 is available to free-tier users. Developers can immediately deploy it through the Claude API, Amazon Bedrock, and Google Cloud Vertex AI.

Challenger Emerges as Frontrunner

Industry observers see Claude Haiku 4.5 as more than just another competitor to GPT. It signals Anthropic's emergence as a leader. The company is shaping an AI ecosystem focused on speed, efficiency, and distributed intelligence.

The Era of Lightweight AI

Compared to its predecessor, Haiku 4.5 strengthens tool use, visual reasoning, and computer operation capabilities. This release marks Anthropic’s push toward the era of multi-agent, lightweight AI.
