Anthropic Launches Opus 5.5 with Enhanced Performance and Lower Costs
Anthropic has released its latest AI model, Opus 5.5, which outperforms the larger Fable model in several benchmarks while being more cost-effective and faster to run. The new version offers a reduced price per output token ($20/mTok vs $25 for previous models) and improved communication style by avoiding jargon and prioritizing key information at the start of responses. This release follows Anthropic’s commitment under CEO Dario Amodei to slow AI development in order to align with progress on safety measures. Opus 5.5 is comparable to Mythos in biology and cybersecurity capabilities, subjecting it to similar safeguards that limit its use for tasks like discovering software exploits or developing biological weapons. Anthropic also announced upcoming releases of Sonnet 5.5 and Haiku 5.5 with expected performance improvements. The company emphasized ongoing efforts to enhance safety training systems and increase public policy involvement in AI governance, planning further details on these initiatives soon.
