Anthropic's Claude 4 models, Opus 4 & Sonnet 4, set new AI benchmarks in coding, reasoning & agents. Both feature extended thinking with tool use & improved memory.
Claude 4 is here!! Anthropic's next generation of models, including the powerful Claude Opus 4 and an upgraded Claude Sonnet 4, has arrived. They're aiming high with this release, especially for coding, advanced reasoning, and building more capable AI agents.
A key new feature for both is "extended thinking with tool use." This allows them to use tools like web search while working on complex problems, which is a big step for more capable agent-like tasks. They've also got improved memory and follow instructions more precisely.
Alongside the new models, Claude Code is now generally available. It brings Claude's help right into your dev workflow with VS Code, JetBrains, and GitHub integrations. You can try Sonnet 4 for free, with Opus 4 on paid plans and various APIs.
@zaczuo Really exciting to see AI models evolving with extended tool use—this feels like a meaningful step toward smarter, more context-aware agents. Can’t wait to test how these upgrades improve real-world coding and problem-solving workflows!

Been waiting to see what Anthropic would come up with next — and Claude 4 looks super impressive! Love how it’s focused on better reasoning and handling longer conversations. Can’t wait to test it out properly. Congrats to the team on this solid launch!
Can take a full repo and improve the code or delete duplicated code or not used? What are the limitations?

Claude 4's extended context + tool integration redefines autonomous agents! 🤖 Opus 4's 200K+ token memory enables recursive self-correction - game changer for complex coding tasks. That RCI (Recursive Chain-of-Thought) implementation must be wild.

Impressed by all the available use cases. It's really awesome. AI focusing on productivity is key

Claude 4 sounds like a major leap forward! I’m also excited to see Claude Code integrated into developer workflows with VS Code, JetBrains, and GitHub - that’s going to be a real productivity booster for teams. How does Claude handle context-switching between tasks or different tools in a session?

Get it to 1m context window and win the whole market.
Congratulations on the launch of Claude 4! 🎉 The "extended thinking with tool use" feature sounds like a game-changer for tackling complex tasks. It's exciting to see innovations that enhance precision and flexibility. Can't wait to integrate this into my workflow! 👏🚀
