# v1.63 - Coworkers, Developer API & Smarter Memory

> Focused chat coworkers, a global Apex API, a rebuilt memory system, admin metadata tools, and newer Claude models.

## Added

* **[Coworkers](/products/logicai/docs/coworkers)** — create focused chat personas in the sidebar, each with its own memory, colour, and standing instructions; keep them private, share with specific teammates, or open to your whole org
* **[Developer API](/products/logicai/docs/developer/overview)** — a global Apex API (`lai.LogicAI`) to call Logic AI from your own Apex, Flows, and triggers
* **[Usage limits](/products/logicai/docs/admin-usage-limits)** — set monthly USD spend limits per source and per user, with a new per-source and per-user spend breakdown in the admin console
* **[Metadata tools](/products/logicai/docs/tools#metadata-tools)** (admins only) — Logic AI can read how your org is built (Apex, Flows, validation/workflow rules, permission sets, LWC/Aura) to explain your automation
* **Smarter [memory](/products/logicai/docs/admin-memory)** — memory is now captured automatically and recalled invisibly, with a health score and 👍/👎 [feedback](/products/logicai/docs/feedback-and-reactions) that auto-tunes how much Logic AI remembers
* **Chats sidebar** — one-line chat rows, delete chats, a resizable divider, and smoother loading

## Fixed

* Fixed a freeze that could occur when giving a message a 👎
* Removed occasional blank assistant messages from the chat

## Improved

* **Newer AI models** — Logic AI now runs on the latest Claude models: **Sonnet 5** (up from Sonnet 4.6) and **Opus 4.8** (up from Opus 4.7). Your existing model selections pick up the upgrade automatically — nothing to reconfigure or reinstall
* Longer, more reliable timeouts on long-running requests
* Memory can be rebuilt from a full history scan, migrating older memory into the new system
