Anthropic releases Claude Opus 4.5, its new flagship model with state-of-the-art coding and agentic performance at lower pricing.

Anthropic upgrades its smartest model with Claude Opus 4.6, industry-leading across agentic coding, computer use, tool use, search and finance.

Anthropic makes Claude Opus 4.7 generally available, a notable improvement on Opus 4.6 in advanced software engineering, especially on the hardest tasks.

Anthropic releases Claude Opus 4.8, stronger across coding, agentic tasks and professional work, with the consistency to keep working on long-running tasks.

Anthropic releases Claude Fable 5.1 and Claude Mythos 5.1 - the same model behind different safeguards - and cuts cache reads by 75%, making typical workloads about 25% cheaper to run than Fable 5.

Anthropic confirmed it operates a wet biology lab in the Bay Area where its models can run physical experiments, its head of life sciences Eric Kauderer-Abrams saying the company is doing real lab work today. Anthropic says the facility's focus is fundamental biology rather than drug discovery, where it partners with pharma customers including Novo Nordisk.

Anthropic had not announced the model; the “Opus 5.1” name comes from leaked early-access identifiers and early tester reports.
