Model levels, one composer menu and Markdown editing
Choose Light, Medium or High for any task, edit Markdown files in place, and find everything from one @ and / menu.
Every model picker now offers three levels: Light, Medium and High. Choose how much power a task needs. d5s keeps each level up to date with strong current models, such as GPT-6 and Claude Opus 5.5.
Edit Markdown files directly
Open a Markdown file from the conversation and click Edit. You change the formatted document in place, and it saves automatically. The agent uses your saved version in its next step.
One menu for @ and /
Type @ or /, or click +, to open the same menu in every composer. It finds files, agents, skills and commands. You can also drop or paste files straight into the composer.
A simpler Agent Builder
Describe the agent in the chat on the left. A live agent card on the right shows the result as you build it.
Connectors you can explore
Each connector now has its own page that shows what it can do. You can share the tool permissions of a connection with your team. HubSpot connects in one step and gives agents CRM tools.
Desktop file access and more
In the desktop app, give an agent access to a folder on your computer: read only, write only, or both. Agents can now read text in scanned images in English, Dutch and Greek. Telegram agents can send you a message first and exchange files in both directions.
