Benzi Beta 1 (v0.4.5)

VS Code extension 0.4.5 · PyPI benzi 0.1.6

Known issue: runtime tracer temporarily broken (October 14, 2026). Traced runs still execute, but they miss calls made inside comprehensions, lambdas and generator expressions, and most method calls on Python 3.9–3.10 projects. A fix is coming in the next release.

What's new since v0.4.2

• Cheaper on Claude models. The fixed part of the system prompt is now cached across sessions.
• Claude Sonnet 5.5 supported.
• Better multi-step work on DeepSeek. Its reasoning now carries over between tool calls.
• Long sessions. Context compaction and resume.
• No more hangs. Shell commands get a 10-minute default limit, which Benzi can raise for test suites and builds. Text search returns partial results after 30 seconds.
• Deeply nested code no longer crashes the indexer.
• More bug fixes.

Install

Benzi Beta 1 (v0.4.2)

VS Code extension 0.4.2 · PyPI benzi 0.1.3

What's new in the VS Code extension

• Settings in the sidebar. A Benzi icon in the activity bar opens a settings panel: pick your model, paste your API key, and log in with your email. No terminal needed. It opens by itself right after install.
• Guided setup. Opening Benzi before setup is finished takes you to the settings panel and says what's left, instead of failing with an error.
• Fixed: blank Benzi panel. Clicking Open again while Benzi was starting, or reopening after the engine stopped, could leave a blank panel until Stop + Restart. Both are fixed.

Install

Benzi Beta 1 (v0.4.1)

VS Code extension 0.4.1 · PyPI benzi 0.1.3

This is Benzi's first public beta. Benzi is a compiler-backed AI coding agent: it compiles your codebase into a resolved, queryable map of calls, data flow, control flow and class hierarchy first, then reads, explains, runs, edits and verifies your code using it. A runtime tracer covers what static analysis can't settle.

Install

• VS Code: install from the Marketplace, or download the .vsix for your platform below and run Extensions: Install from VSIX…
• MCP server: pip install benzi, then point your MCP client at benzi-mcp. Also listed in the official MCP Registry as net.varianttech/benzi.
• Headless CLI: pip install benzi, then benzi-headless <repo> "your question".
• Browser demo: paste any public GitHub repo at varianttech.net/demo. No install, read-only.

Run benzi-login once before using the VS Code extension, MCP or headless. Bring your own model key; Benzi is free to use.

What's in this release

• Builds for Windows x64, Linux x64, macOS Apple Silicon and macOS Intel
• PyPI wheels for Python 3.11, 3.12, 3.13 and 3.14
• Three commands: benzi-login, benzi-mcp, benzi-headless
• MCP server runs over stdio and lists its tools before login, so clients can discover it; login is asked for on first tool call
• Ten languages plus a markup engine for HTML, CSS and DOM-JS
