Anthropic released a new AI model, "Claude Opus 5," on July 24 (local time), which is cheaper and lighter than Fable 5. It delivers performance close to Fable 5 at roughly half the cost, priced at 5 dollars per 1 million input tokens and 25 dollars per 1 million output tokens, compared to Fable 5’s 10 dollars and 50 dollars. The AI industry has seen a surge in lightweight model releases as computing power becomes more expensive, with businesses prioritizing response speed, token costs, and power consumption over benchmark scores by 1–2 points. Opus 5 introduces an "Effort" feature that allows users to adjust computational resources per task, using less computing power for simple queries and concentrating operations on complex tasks, reflecting a shift in competition toward "cost per task completion" and "task volume processed per unit time." Google also recently unveiled three smaller, faster models: "Gemini 3.6 Flash," "Gemini 3.5 Flash Lite," and "Gemini 3.5 Flash Cyber" for cybersecurity, focusing on low-cost, high-volume processing for tasks like document handling, customer service, search, and security.
