New Models, Smarter Agents, and Better Control

April 2026 brings major model updates, a new auto permission mode for faster workflows, image generation built in, and a smoother experience for managing agents and models in your IDE.

​
New Features

​
GPT 5.5 Support

The latest frontier model from OpenAI is now available in Zencoder. Use GPT 5.5 for your most complex tasks — planning, debugging, and research workflows.

​
Claude Opus 4.7 with Streaming Thinking

Claude Opus 4.7 is now supported with streaming thinking — watch the model’s reasoning process in real time as it works through your problem.

​
Auto Permission Mode

Hands-Free Agent Execution

Let the agent run without pausing for approvals on every action.
A new Auto permission mode for Claude Code lets agents execute without manual approval at each step. Ideal for trusted workflows where you want the agent to move fast.

​
Image Generation

Generate Images in Chat

Ask the agent to create images — logos, diagrams, mockups — right inside your IDE.
Image generation is now enabled by default. Ask the agent to create visuals and see results rendered inline in chat.

​
Agent-Browser Skill

A new agent-browser skill replaces the previous Playwright skill, giving agents improved browser automation capabilities for testing and web interaction tasks.

​
Frontend Design Skill

A new built-in frontend-design skill helps agents generate production-quality UI designs and HTML mockups directly from your descriptions.

​
MCP Tool Permissions

Control Which Tools Agents Can Use

Review and approve MCP tool access before agents use them.
Agents now request permission before using MCP tools, giving you visibility and control over which external tools are invoked during a task. You can also configure “Always allow” for trusted tools in settings.

​
Delete Rules from UI

You can now delete Zen Rules directly from the VS Code and JetBrains UI — no need to manually remove files.

​
Improvements

​
Model and Agent Experience

  • Improved model selector — clearer display of the current engine and model
  • Optimized system prompts for Claude 4.6 and GPT 5.4 model families
  • Updated comprehensive review skill for better multi-model feedback
  • Updated cross-review skill with improved output quality

​
Agent Reliability

  • Fixed agent reporting it edited a file when it didn’t actually make changes
  • Fixed Anthropic models stopping prematurely due to output token limits with adaptive thinking
  • Fixed long-running agent sessions failing with MCP tools
  • Fixed file edits now written atomically to prevent corruption

​
User Experience

  • Fixed empty .zencoder/workflows folders being created in every project
  • Fixed session data corruption in VS Code
  • Fixed sound notifications in JetBrains checking project window focus instead of app focus
  • Fixed Ask Questions tool working correctly in Codex CLI for both VS Code and JetBrains
  • 3.48.0 (April 14, 2026)
