Anthropic is making introductory pricing for its Claude 5 Sonnet AI model permanent. The company canceled a 50% price increase. It had scheduled the hike for September 1. Input tokens will remain at $2 per million. Output tokens will stay at $10 per million. This move provides cost stability for developers building complex, agent-based AI tasks.

The decision intensifies competition against rivals OpenAI and Google. Anthropic positions the Sonnet model as a high-performance, affordable alternative. The company has reportedly reached $47 billion in annualized revenue. Anthropic is currently preparing for an IPO. Tech giants Google and Amazon back the firm.
