## Problem When an AI chat conversation is reloaded from the DB (page refresh or initial load), message parts are returned without guaranteed ordering. The renderer groups reasoning/thinking steps only when they are **contiguous** — so if `reasoning` parts land after the `text` part, thinking blocks appear below the final answer, and can appear duplicated or split. This only surfaces with reasoning models (OpenRouter, etc.) because those produce multiple reasoning/tool/text parts per message, making ordering observable. Simple text-only messages aren't affected. ## Root cause `AgentChatService.getMessagesForThread()` fetches `parts` via a TypeORM relation with no ORDER BY on `orderIndex`. The DB can return parts in any order. `mapDBMessagesToUIMessages()` then calls `dbMessage.parts.map(...)` directly, without sorting. A parallel server-side utility (`mapDBPartsToUIMessageParts.ts`) already sorts by `orderIndex` — this fix makes the frontend fetch path consistent with it. ## Fix Sort parts by `orderIndex` before mapping to UI parts in `mapDBMessagesToUIMessages.ts`. ```ts parts: [...dbMessage.parts] .sort((a, b) => a.orderIndex - b.orderIndex) .map(mapDBPartToUIMessagePart), ``` `orderIndex` is already included in `GetChatMessagesDocument` — no schema or query changes needed. ## Test 1. Open Ask AI with a reasoning model (e.g. via OpenRouter). 2. Run a prompt that produces thinking steps. 3. Hard-refresh the page. 4. Thinking blocks should appear collapsed above the final answer, not below it.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
