🤖Anthropic Unveils Opus 5 AI Model With $2 MTok Input Cost

Cheaper and Smarter Than the Competition?

TL;DR

Anthropic just dropped Opus 5 with a $2 MTok input price tag. It beats Fable 5 in cost-efficiency while outperforming GPT-5.6 Sol on agentic coding tasks and cybersecurity benchmarks.

Anthropic has released the new Opus 5 AI model, priced at just $2 per million tokens (MTok) for input and $25 for output. This makes it cheaper than competitors like Fable 5 ($10/MTok input) and GPT-5.6 Sol ($5/MTok input). For developers, this means more budget-friendly access to cutting-edge AI capabilities. Opus 5 leads the Artificial Analysis Intelligence Index at 61 points, one ahead of Fable 5. It also excels in cybersecurity tasks with an OSS-Fuzz benchmark score close to Mythos but is less likely to weaponize findings. The model's improved alignment means it’s safer for sensitive applications.
