Anthropic Launches Claude Opus 5 at Half the Price of Fable 5

Anthropic's new Claude Opus 5 undercuts competitors on price while claiming comparable performance, potentially reshaping the economics of the booming artificial intelligence market just as enterprises are beginning to deploy AI at scale. The move marks an aggressive pivot by the San Francisco startup, which has positioned itself as a safety-focused alternative to OpenAI, suggesting that the era of premium pricing for frontier AI models may be ending faster than expected. With major tech companies racing to lock in customers through pricing power, Anthropic's bet that it can win market share through affordability rather than exclusive capabilities will test whether performance parity is finally becoming table stakes in the AI wars.
