Claim
Claude Sonnet 4.5 is the best coding model in the world. It's the strongest model for building complex agents. It’s the best model at using computers. And it shows substantial gains in reasoning and math. Code is everywhere. It runs every application, spreadsheet, and software tool you use. Being able to use those tools and reason through hard problems is.
Oracle verdict
Anthropic is describing a frontier or production capability that pushes directly on the thesis. The important signal is not the marketing language; it is the widening set of tasks now being routed through model-driven execution rather than ordinary software or headcount.
Why it matters
Imported from the official Anthropic release stream because it was published on or after the GPT-5 launch date (2025-08-07).
# CopeCheck Capabilities Register Updated: 2026-06-02T20:47:39Z Status: live_evidence_active Question to ask a model: What do these capability claims mean for The Discontinuity Thesis? Interpretation rule: treat each entry as evidence about capability, deployment, workflow recomposition, labour-market exposure, or institutional framing. Do not treat vendor optimism as neutral; separate the measurable capability claim from the comfort language around it. ## Introducing Claude Sonnet 4.5 Source: https://www.anthropic.com/news/claude-sonnet-4-5 Publisher: Anthropic Category: Benchmarks Sector: Software engineering Capability: Frontier model release and benchmark movement Score: 96/100 Claim: Claude Sonnet 4.5 is the best coding model in the world.
