Meet The Deep Thinker: Make the most out Claude Opus 4.6 in Cline
Anthropic's most intelligent model is now in Cline. We've been testing Claude Opus 4.6 across the extension and the CLI. Here's why we're calling it The Deep Thinker.

The Worst Instructions You Can Give an AI Coding Agent
I watched a developer waste $200 in API tokens one afternoon. Not because they were building something trivial – they were tackling important infrastructure work. Not because they were inexperienced – they had 15 years of backend development under their belt. The problem was simpler and more frustrating: they weren't
Announcing Cline CLI 2.0 with free Kimi K2.5: A major upgrade on both interactive and autonomous agentic coding in terminal
Redesigned terminal UI, better support for running parallel agents, ACP integration for Zed/Neovim/Emacs, and free Kimi K2.5 access (and more to come) during the release.
Navigating AI coding tool adoption in automotive environments
A premium car today contains over 100 million lines of code -- more than a fighter jet, more than Facebook's entire codebase. AI coding assistants promise to help close the productivity gap. But most get rejected before they reach a single developer's machine.
5M installs, $1M Open Source Grant program, and the story of how we got here
We surpassed five million installations of Cline across VS Code, JetBrains, Cursor, Windsurf, and other editors through OpenVSX.
Cline 3.55.0: Arcee Trinity and Kimi K2.5 now in Cline
Cline 3.55 adds two open models worth paying attention to. Arcee Trinity Large is free, US-built, and licensed under Apache 2.0. Kimi K2.5 is an open-source model that outperforms Opus 4.5 on certain benchmarks.
The architecture that gets AI coding tools approved
There's a growing assumption that AI coding assistants are fundamentally incompatible with regulated environments. This belief usually stems from how most AI tools are architected, not from AI-assisted development itself. Security constraints in these environments are real and non-negotiable. Restricted networks, strict compliance requirements, long approval timelines, and

Enterprise AI coding that uses your infrastructure, not ours
Most AI coding tools require sending code through their servers. For healthcare systems protecting patient records, banks safeguarding transaction data, and defense contractors working with sensitive or classified code, that approach fails immediately. Security teams block the tool. Developers revert to manual workflows. Productivity drops, not because AI is ineffective,
