New Anthropic, OpenAI Models Make Same Promise: A Little More for a Lot Less Money
- Anthropic unveiled Claude Opus 5.5 on Tuesday, generating output over 30% faster than Opus 5 while cutting typical workload costs by around 40%. The model matches Claude Fable 5.1 performance on most tasks.
- The release follows CEO Dario Amodei's September 12 call to "pace the frontier" of AI development, urging the industry to slow capability rollouts to address safety concerns. Opus 5.5 is Anthropic's first major model since that announcement.
- Independent safety researchers Frontier Design and METR tested Opus 5.5 before release, with the model priced at $4 per million input tokens and $20 per million output tokens. Internal benchmarks show 66.4% on Terminal-Bench 4.0, outperforming competitors.
- OpenAI simultaneously launched lower-cost GPT-6 Sol and Luna models, intensifying pricing competition for enterprise developers. Fortune reports this commoditization of flagship capabilities could compress margins amid competition from low-cost open-weight alternatives.
- Anthropic plans to release Claude Sonnet 5.5 and Claude Haiku 5.5 in the coming weeks, expanding the new Claude 5.5 family. Reports suggest the company could seek a valuation approaching $2 trillion ahead of a potential initial public offering.
