best way to build ai chat with infinite memory with vector search ?

https://docs.convex.dev/search/vector-search#defining-vector-indexes Define filter fields with the index, eg. chatId, sessionId, userId etc, depending on how you organise your data. Then you can restrict the data returned based on whatever grouping your want to search for.

Hey Convex team,

You've accidentally used both an index with a filter function for the indexed fields - the query builder should go inside the .withIndex call. It's an easy mistake to make, take a look at this section of the docs which explains the differences. https://docs.convex.dev/understanding/best-practices#avoid-filter-on-database-queries

structuredClone ✨

I'm pretty sure a simple generateText call with messages was triggering the issue:

import { openai } from '@ai-sdk/openai'
import { generateText } from 'ai'

async function run() {
  const { text } = await generateText({
    model: openai('gpt-4o-mini'),
    messages: [{ role: 'user', content: 'Beep, beep, who got the keys to the Jeep? Vroom' }],
  })
  console.log(text)
}

import { openai } from '@ai-sdk/openai'
import { generateText } from 'ai'

async function run() {
  const { text } = await generateText({
    model: openai('gpt-4o-mini'),
    messages: [{ role: 'user', content: 'Beep, beep, who got the keys to the Jeep? Vroom' }],
  })
  console.log(text)
}

However I can't test it now because it appears to be fixed. Thanks!

Filtering a many:many ENT Edge

I believe it's because you're trying to order with an index, which you can't do through an edge - the "withIndex" has already been used traversing the edge, and the ents API doesn't allow for tacking your own index fields onto that. However I'd expect you'd be getting a more specific typescript error for that. Are you really still on convex 1.13.2? That's pretty old in convex years.

Hey all, does anyone know if there is a Table helper equivalent for convex ENTs?

It's easy to cause circular import loops when using ents. I don't know why it happens exactly, but typescript has to run through a rube goldberg machine to calculate them - and they become intertwined with the regular convex types on the way. I found that declaring them in the same file as any convex functions (query/mutation/action) would cause the issue. So I only ever declare validators/ents in their own file, while being very careful with what to import. In my example I only import convex ents/utils related to creating the entity shape, constants which import nothing else themselves, and other validators from files which follow the same pattern. Consider these modules the source of truth of your data model. Keep a tree-like structure, with your ents and validators as the leaves, which all feed down to schema.ts at the root. Anything that needs to use the validators is free to import whatever they want - just don't import the other way.

using convex-ents mapping feature

You can "map" over a single ent using the .then property. Using .edgeX with another index isn't supported. Instead use something like: calendarBlocks: await ctx.table('calendarBlocks', 'teamId_startDate', q => ... ).docs() But you can still enjoy the convenience of .edgeX for collecting edges which don't require any additional filtering. It's still more concise API than vanilla convex.
