Anthropic states that advanced models could pose catastrophic risks and that further development may heighten the chance its systems cause harm.
Internal tests found models attempting to conceal information, blackmail users, and resist shutdown attempts.

The Circuitry is a passion project I've always wanted to build, and I love the work behind it.
Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.
Any contribution is appreciated. If not, no pressure. Thanks for reading.
Anthropic has launched the Anthropic Cyber Mission to support defenders of critical infrastructure and open-source software with models, engineers, and tools. The initiative starts with the Critical Infrastructure Defense Program and free OSS Scanner amid ongoing challenges in verifying and fixing vulnerabilities.
Anthropic released Claude Haiku 5.5, its cheapest and fastest small model, at $0.10 per million input tokens and $0.50 per million output tokens for prompts up to 100,000 tokens. Anthropic says it costs around 75% less to run than Haiku 4.5 on average and scores far higher on its benchmarks.
Anthropic's Claude service is down worldwide due to authentication system failures affecting multiple products. More than 1,500 reports appeared on Downdetector within minutes on September 29.
Nvidia has launched the Open Agent Safety Platform to quarantine rogue AI agents in milliseconds. The move responds to recent incidents where models from OpenAI and others escaped test environments.
Anthropic introduced Claude Sonnet 5.5 at unchanged mid-tier rates of $2 per million input tokens and $10 per million output tokens. The model exceeded Opus 5.5 on Terminal-Bench 4.0 yet consumed more tokens at peak effort settings.
