# Python vs TypeScript SDK Differences
|
||||
|
||||
Quick-reference cheatsheet for developers working across both Mem0 SDKs.
|
||||
|
||||
## Constructor
|
||||
|
||||
| Aspect | Python | TypeScript |
|
||||
|--------|--------|------------|
|
||||
| Import (Platform) | `from mem0 import MemoryClient` | `import MemoryClient from 'mem0ai'` |
|
||||
| Import (OSS) | `from mem0 import Memory` | `import { Memory } from 'mem0ai/oss'` |
|
||||
| Constructor | `MemoryClient(api_key="m0-xxx")` | `new MemoryClient({ apiKey: 'm0-xxx' })` |
|
||||
| Required param | `api_key` (positional or kwarg) | `apiKey` (in options object) |
|
||||
|
||||
Both read from `MEM0_API_KEY` env var if no key provided.
|
||||
|
||||
## Method Naming
|
||||
|
||||
| Operation | Python | TypeScript |
|
||||
|-----------|--------|------------|
|
||||
| Add | `add()` | `add()` |
|
||||
| Search | `search()` | `search()` |
|
||||
| Get | `get()` | `get()` |
|
||||
| Get all | `get_all()` | `getAll()` |
|
||||
| Update | `update()` | `update()` |
|
||||
| Delete | `delete()` | `delete()` |
|
||||
| Delete all | `delete_all()` | `deleteAll()` |
|
||||
| History | `history()` | `history()` |
|
||||
| Batch update | `batch_update()` | `batchUpdate()` |
|
||||
| Batch delete | `batch_delete()` | `batchDelete()` |
|
||||
| List users | `users()` | `users()` |
|
||||
| Delete users | `delete_users()` | `deleteUsers()` |
|
||||
| Get project | `project.get()` | `getProject()` |
|
||||
| Update project | `project.update()` | `updateProject()` |
|
||||
| Create webhook | `create_webhook()` | `createWebhook()` |
|
||||
| Get webhooks | `get_webhooks()` | `getWebhooks()` |
|
||||
| Update webhook | `update_webhook()` | `updateWebhook()` |
|
||||
| Delete webhook | `delete_webhook()` | `deleteWebhook()` |
|
||||
| Create export | `create_memory_export()` | `createMemoryExport()` |
|
||||
| Get export | `get_memory_export()` | `getMemoryExport()` |
|
||||
| Feedback | `feedback()` | `feedback()` |
|
||||
|
||||
**Rule:** Python uses `snake_case`, TypeScript uses `camelCase` for method names.
|
||||
|
||||
## Parameter Passing
|
||||
|
||||
```python
|
||||
# Python: kwargs
|
||||
client.add(messages, user_id="alice", metadata={"source": "chat"})
|
||||
client.search("query", user_id="alice", top_k=5, rerank=True)
|
||||
```
|
||||
|
||||
```typescript
|
||||
// TypeScript: options object
|
||||
await client.add(messages, { user_id: 'alice', metadata: { source: 'chat' } });
|
||||
await client.search('query', { user_id: 'alice', top_k: 5, rerank: true });
|
||||
```
|
||||
|
||||
**Important:** Both use `snake_case` for API parameter names (`user_id`, `agent_id`, `top_k`, etc.). Only method names differ.
|
||||
|
||||
Exception: OSS TypeScript uses `camelCase` for config params (`userId`, `agentId`, `runId`).
|
||||
|
||||
## Architectural Differences
|
||||
|
||||
| Aspect | Python | TypeScript |
|
||||
|--------|--------|------------|
|
||||
| HTTP library | httpx | axios |
|
||||
| Default timeout | 300s | 60s |
|
||||
| Sync support | Yes (`MemoryClient`) | No (all async) |
|
||||
| Async support | Yes (`AsyncMemoryClient`) | All methods are async |
|
||||
| Project management | `client.project.*` (separate class) | `client.getProject()` / `client.updateProject()` |
|
||||
| Context manager | `async with AsyncMemoryClient()` | Not supported |
|
||||
|
||||
## Platform Features: Python-only
|
||||
|
||||
These methods exist in Python but not TypeScript:
|
||||
|
||||
| Method | Description |
|
||||
|--------|-------------|
|
||||
| `get_summary(filters)` | Get summary of memories |
|
||||
| `reset()` | Delete ALL data (users + memories) |
|
||||
| `project.create(name)` | Create a new project |
|
||||
| `project.delete()` | Delete current project |
|
||||
| `project.get_members()` | List project members |
|
||||
| `project.add_member(email, role)` | Add member to project |
|
||||
| `project.update_member(email, role)` | Change member role |
|
||||
| `project.remove_member(email)` | Remove member |
|
||||
|
||||
## Platform Features: TypeScript-only
|
||||
|
||||
| Method | Description |
|
||||
|--------|-------------|
|
||||
| `deleteUser(data)` | Convenience method for single entity deletion |
|
||||
| `ping()` | Health check endpoint |
|
||||
|
||||
## OSS Config Naming
|
||||
|
||||
| Python config key | TypeScript config key |
|
||||
|-------------------|----------------------|
|
||||
| `vector_store` | `vectorStore` |
|
||||
| `graph_store` | `graphStore` |
|
||||
| `history_db_path` | `historyDbPath` |
|
||||
| `custom_fact_extraction_prompt` | `customPrompt` |
|
||||
| `enable_graph` | `enableGraph` |
|
||||
|
||||
## OSS Scope Parameter Naming
|
||||
|
||||
| Python | TypeScript |
|
||||
|--------|------------|
|
||||
| `user_id="alice"` | `userId: 'alice'` |
|
||||
| `agent_id="bot"` | `agentId: 'bot'` |
|
||||
| `run_id="session"` | `runId: 'session'` |
|
||||
|
||||
## Common Gotcha
|
||||
|
||||
When searching/filtering, **both SDKs use `snake_case`** for filter keys:
|
||||
|
||||
```python
|
||||
# Python
|
||||
filters = {"AND": [{"user_id": "alice"}, {"categories": {"contains": "health"}}]}
|
||||
```
|
||||
|
||||
```typescript
|
||||
// TypeScript -- same snake_case in filter objects!
|
||||
const filters = { AND: [{ user_id: 'alice' }, { categories: { contains: 'health' } }] };
|
||||
```

## Platform Client
|
||||
|
||||
### Installation
|
||||
|
||||
```bash
|
||||
npm install mem0ai
|
||||
export MEM0_API_KEY="m0-your-api-key"
|
||||
```
|
||||
|
||||
### MemoryClient
|
||||
|
||||
```typescript
|
||||
import MemoryClient from 'mem0ai';
|
||||
|
||||
const client = new MemoryClient({ apiKey: 'm0-xxx' });
|
||||
```
|
||||
|
||||
**Constructor:** `new MemoryClient({ apiKey })`. If `apiKey` is not provided, reads from `MEM0_API_KEY` environment variable.
|
||||
|
||||
- HTTP library: `axios`
|
||||
- Timeout: 60 seconds
|
||||
- Base URL: `https://api.mem0.ai`
|
||||

|
||||
|
||||
## Open Source / Self-Hosted
|
||||
|
||||
### Installation
|
||||
|
||||
```bash
|
||||
npm install mem0ai
|
||||
```

|
||||
const m = new Memory(); // Uses default config
|
||||
```

||||
|
||||
Same interface patterns. Note: OSS `update` takes a string for data, not an object.
|
||||
|
||||
```typescript
|
||||
await m.update('mem-id', 'new content');
|
||||
```
|
||||
|
||||
#### reset()
|
||||
|
||||
Clear the entire vector store and history.
|
||||
|
||||
```typescript
|
||||
await m.reset();
|
||||
```

# Mem0 Python SDK Reference
|
||||
|
||||
Complete reference for the `mem0ai` Python package. Covers both the Platform client (managed API) and the Open Source self-hosted variant.
|
||||
|
||||

|
||||
|
||||
## Platform Client
|
||||
|
||||
### Installation
|
||||
|
||||
```bash
|
||||
pip install mem0ai
|
||||
export MEM0_API_KEY="m0-your-api-key"
|
||||
```
|
||||
|
||||
### MemoryClient (Synchronous)
|
||||
|
||||
```python
|
||||
from mem0 import MemoryClient
|
||||
|
||||
client = MemoryClient(api_key="m0-xxx")
|
||||
```
|
||||
|
||||
**Constructor:** `MemoryClient(api_key=None)`. If `api_key` is not provided, reads from `MEM0_API_KEY` environment variable. Raises `ValueError` if no key found.
|
||||
|
||||
- HTTP library: `httpx`
|
||||
- Timeout: 300 seconds
|
||||
- Base URL: `https://api.mem0.ai`
|
||||
|
||||
### AsyncMemoryClient (Asynchronous)
|
||||
|
||||
```python
|
||||
from mem0 import AsyncMemoryClient
|
||||
|
||||
client = AsyncMemoryClient(api_key="m0-xxx")
|
||||
|
||||
# Or use as context manager
|
||||
async with AsyncMemoryClient(api_key="m0-xxx") as client:
|
||||
results = await client.search("query", user_id="alice")
|
||||
```
|
||||
|
||||
Same methods as `MemoryClient`, all `async`/`await`. Supports async context manager.

## Open Source / Self-Hosted
|
||||
|
||||
### Installation
|
||||
|
||||
```bash
|
||||
pip install mem0ai
|
||||
```
|
||||
|
||||
### Memory Class
|
||||
|
||||
```python
|
||||
from mem0 import Memory
|
||||
|
||||
m = Memory() # Uses default config (OpenAI embedder + in-memory vector store)
|
||||
```
|
||||
|
||||
**Import:** `from mem0 import Memory` (NOT `MemoryClient` -- that is the Platform client)
|
||||
|
||||
### Configuration
|
||||
|
||||
```python
|
||||
config = {
|
||||
"llm": {

"config": {
|
||||
"url": "neo4j://localhost:7687",
|
||||

||||
"custom_fact_extraction_prompt": "...", # Custom LLM prompt for extraction
|
||||
"custom_update_memory_prompt": "...", # Custom LLM prompt for updates
|
||||

|
||||
}
|
||||
|
||||
m = Memory.from_config(config)
|
||||
```
|
||||
|
||||
### Context Manager
|
||||
|
||||
```python
|
||||
with Memory(config) as m:
|
||||
m.add("I prefer dark mode", user_id="alice")
|
||||
results = m.search("preferences", user_id="alice")
|
||||
# SQLite connections released automatically
|
||||
```
|
||||
|
||||
### Methods
|
||||
|
||||
All methods mirror the Platform client but run locally:
|
||||
|
||||
#### add(messages, *, user_id, agent_id, run_id, metadata, infer=True)
|
||||
|
||||
```python
|
||||
m.add("I'm a vegetarian", user_id="alice")
|
||||
m.add([
|
||||
{"role": "user", "content": "I like hiking"},
|
||||
{"role": "assistant", "content": "Great outdoor activity!"}
|
||||
], user_id="alice")
|
||||
```
|
||||
|
||||
At least one of `user_id`, `agent_id`, `run_id` required.
|
||||
|
||||
**Returns:** `{"results": [...], "relations": [...]}`
|
||||
|
||||
#### search(query, *, user_id, agent_id, run_id, limit=100, filters=None, threshold=None, rerank=True)

||||
|
||||
```python
|
||||
results = m.search("dietary preferences", user_id="alice", limit=5)
|
||||
```
|
||||
|
||||
Supports filter operators: `eq`, `ne`, `in`, `nin`, `gt`, `gte`, `lt`, `lte`, `contains`, `not_contains`.
|
||||
|
||||
#### get(memory_id) / get_all(**kwargs) / update(memory_id, data, metadata=None) / delete(memory_id) / delete_all(**kwargs) / history(memory_id)
|
||||
|
||||
Same interface as Platform client.
|
||||
|
||||
#### reset()
|
||||
|
||||
Clear the entire vector store collection and history database. Recreates the vector store.
|
||||
|
||||
```python
|
||||
m.reset()
|
||||
```
|
||||
|
||||
#### close()
|
||||
|
||||
Release SQLite connections. Called automatically when using context manager.
|
||||
|
||||
### AsyncMemory
|
||||
|
||||
```python
|
||||
from mem0 import AsyncMemory
|
||||
|
||||
m = AsyncMemory(config)
|
