## Key Highlights

LiteLLM v1.70.1-stable is live now. Here are the key highlights of this release:

- **Gemini Realtime API**: You can now call Gemini's Live API via the OpenAI /v1/realtime API
- **Spend Logs Retention Period**: Enable deleting spend logs older than a certain period.
- **PII Masking 2.0**: Easily configure masking or blocking specific PII/PHI entities on the UI

## Gemini Realtime API

<Image img={require('../../img/gemini_realtime.png')}/>


This release brings support for calling Gemini's realtime models (e.g. gemini-2.0-flash-live) via OpenAI's /v1/realtime API. This is great for developers as it lets them easily switch from OpenAI to Gemini by just changing the model name. 

Key Highlights: 
- Support for text + audio input/output
- Support for setting session configurations (modality, instructions, activity detection) in the OpenAI format
- Support for logging + usage tracking for realtime sessions

This is currently supported via Google AI Studio. We plan to release VertexAI support over the coming week.

## Spend Logs Retention Period

<Image img={require('../../img/delete_spend_logs.jpg')}/>



This release enables deleting LiteLLM Spend Logs older than a certain period. Since we now enable storing the raw request/response in the logs, deleting old logs ensures the database remains performant in production. 

[**Read more**](../../docs/proxy/spend_logs_deletion)

## PII Masking 2.0

<Image img={require('../../img/pii_masking_v2.png')}/>

This release brings improvements to our Presidio PII Integration. As a Proxy Admin, you now have the ability to:

- Mask or block specific entities (e.g., block medical licenses while masking other entities like emails).
- Monitor guardrails in production. LiteLLM Logs will now show you the guardrail run, the entities it detected, and its confidence score for each entity.
