## Future plans
|
||||
* better error handling
|
||||
* model changing, esp. something for swapping loras or embedding models
|
||||
* consider switching to FastAPI + starlette for SSE (openai SSE seems non-standard)
|
||||
* do something about rate limiting or locking requests for completions, most systems will only be able handle a single request at a time before OOM
