Anthropic launches Claude.dev: Guides, agents & cost insights
Anthropic’s new site Claude.dev offers practical blog posts, guides, agents, and cost analyses for Sonnet 5.5, Opus 5.5, and internal model usage.
Save: Anthropic launched a new site for developers — claude.dev.
This is not documentation, but a practical blog of the engineering team.
Documentation is still located at code.claude.com/docs. On claude.dev they publish detailed articles, practical scenarios, team experiences and live cases.
Main sections — agents, engineering, practical guides and Skills.
Now there are especially interesting materials about development with Sonnet 5.5, the cost of running tasks on Opus 5.5, new rules of contextual engineering for the next generation of models, triple acceleration claude.ai in two weeks, and automatic grading design using Claude.
It’s also interesting to see how Anthropic itself uses models inside the company and calculates the cost of work. There are also practical videos from the Claude Code team, Ramp, and DoorDash.
P.S. if you click TERMINAL, the site turns into a command-line interface.
