Agents
What is agent memory?
Agent memory is durable, queryable state an agent reads and writes across turns: messages, retrieved facts, and tool results, not a hidden JSON file.
Updated
How it works
- Turns and artifacts are rows.
- The next call reads the rows it needs.
- You can query what the agent saw last week.
What it is not
It is not the model’s context window, and it is not a cache with no schema.
agent memory: this, and the thing it is confused with
| This | Not this | |
|---|---|---|
| Lifetime | Across processes | Until the prompt ends |
| Shape | Tables you can query | A blob of messages |
| Media | Can sit on the same rows | Text only, usually |
Where Pixeltable fits
Pixeltable stores that memory as tables the agent reads with a query and writes with an insert.
