Delete a specific memory by ID.
This is the unified deletion method that searches across all memory types
and all backends (SQLite, ChromaDB, Mem0, MongoDB).
Particularly useful for:
* Cleaning up image-based memories after processing to free context window
* Removing outdated or incorrect information
* Privacy compliance (selective erasure)
## Signature
```python theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
def delete_memory(memory_id: str, memory_type: Optional[str]) -> bool
```
## Parameters
The unique ID of the memory to delete
Optional type hint to narrow search: 'short\_term', 'long\_term' If None, searches all types.
### Returns
True if memory was found and deleted, False otherwise
## Usage
```python theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
# Delete a specific image analysis memory
memory.delete_memory("1705123456789")
# Delete with type hint for faster lookup
memory.delete_memory("1705123456789", memory_type="short_term")
```
