Here's the simple idea: better planning leads to better results. Plan Mode asks clarifying questions upfront, lets Alter understand your intent deeply, and creates a structured plan you review before anything happens. --- ## Why Plan Mode Matters When you're working on something complex, extracting data from multiple sources, building a workflow with specific requirements, or solving a problem with many moving parts, the difference between a rough request and a well-understood one is enormous. Traditional mode works great for quick tasks. But for complex work, jumping straight to execution can mean: - Missed details that require rework - Assumptions about what you actually need - Changes made before you've had a chance to review the approach **Plan Mode inverts this flow.** It makes Alter pause, ask questions, and think through the problem before taking action. ![](https://list2.alterhq.com/content/images/media-beehiiv-com/cdn-cgi/image/fit-scale-down-format-auto-onerror-redirect-quality-80/uploads/asset/file/58bb3967-7bcc-4a3f-8e10-ff260b36b980/plan-mode-t-1771582868.png) --- ## How It Works 1. **Activate Plan Mode** — Select Plan mode in the Hub, on the bottom left 2. **Answer Clarifying Questions** — Alter asks targeted questions to understand your intent 3. **Review the Plan** — You see a structured breakdown of the approach before execution begins 4. **Approve & Execute** — Only after you've reviewed does Alter move forward Think of it as having an experienced collaborator who asks "before we do this, can you help me understand..." --- ## New models We’ve been adding new models in the past few weeks, Sonnet 4.6, GLM 5, Minimax 2.5, Qwen3.5-397B-A17B and FM2-24B-A2B-Preview to the roaster. Voxstral 2 is also becoming our main STT cloud processor, keeping Deepgram Nova as a fallback. --- We'd love your feedback. Hit us up in Discord or email if you have thoughts on how Plan Mode works for you and if you have a new favorite model in town. See you next week. **Olivier & Samuel** ## Full Changelog ### New Features & Enhancements - **Plan Mode**: Introduced Plan Mode to help structure complex workflows by planning before execution - **Flow Engine**: Add transform/chaining support between tools and a summarization step to avoid context bloat - **New Models**: Added Sonnet 4.6, GLM 5, Minimax 2.5, Qwen3.5-397B-A17B, and FM2-24B-A2B-Preview to the model roster - **Speech-to-Text**: Voxtral 2 is now the main cloud STT processor, with Deepgram Nova kept as a fallback ### Bug Fixes & Stability - **Hub Input & Navigation**: Fixed hub input expansion and context strip navigation issues - **Hub UI Stability**: Fixed flickering scroll with tool calls and removed transparency effects from conversation view - **Conversation & Sidebar**: Fixed conversations sometimes not showing in sidebar, plus performance optimizations - **Malformed Tool Calls**: Server-side fixes to avoid malformed tool calls - **Usage**: Improved fair-use display behavior - **Transcript Indexing**: Fixed transcripts renamed from the notch not being reindexed properly - **Menus & Action Editor**: Fixed picky click hit areas in Alter menu categories and removed unwanted autofocus in action editor general pane - **Microphone Sessions**: Improved recording stop flow by clearing live sessions correctly, avoiding stray sessions, removing duplicate reset handling, improving stop reactivity, and storing failed recordings in history when possible - **Microphone Errors**: Better handling of session start failures - **Floating Widget**: Reverted change breaking context retrieval ### Videos on Alter 1.
