Title: Anthropic Releases Claude 4 Models That Can Autonomously Work For
Nearly a Full Corporate Workday

Link: https://slashdot.org/story/25/05/22/1653257/a...

Anthropic launched Claude Opus 4 and Claude Sonnet 4 today, positioning Opus
4 as the world's leading coding model with 72.5% performance on SWE-bench and
43.2% on Terminal-bench. Both models feature hybrid architecture supporting
near-instant responses and extended thinking modes for complex reasoning
tasks. The models introduce parallel tool execution and memory capabilities
that allow Claude to extract and save key facts when given local file access.
Claude Code, previously in research preview, is now generally available with
new VS Code and JetBrains integrations that display edits directly in
developers' files. GitHub integration enables Claude to respond to pull
request feedback and fix CI errors through a new beta SDK. Pricing remains
consistent with previous generations at $15/$75 per million tokens for Opus 4
and $3/$15 for Sonnet 4. Both models are available through Claude's web
interface, the Anthropic API, Amazon Bedrock, and Google Cloud's Vertex AI.
Extended thinking capabilities are included in Pro, Max, Team, and Enterprise
plans, with Sonnet 4 also available to free users. The startup, which counts
Amazon and Google among its investors, said Claude Opus 4 could autonomously
work for nearly a full corporate workday -- seven hours. CNBC adds: "I do a
lot of writing with Claude, and I think prior to Opus 4 and Sonnet 4, I was
mostly using the models as a thinking partner, but still doing most of the
writing myself," Mike Krieger, Anthropic's chief product officer, said in an
interview. "And they've crossed this threshold where now most of my writing
is actually ... Opus mostly, and it now is unrecognizable from my writing."
Krieger added, "I love that we're kind of pushing the frontier on two sides.
Like one is the coding piece and agentic behavior overall, and that's
powering a lot of these coding startups. ... But then also, we're pushing the
frontier on how these models can actually learn from and then be a really
useful writing partner, too."
