13. ⚡ Support for Claude Messages format, [API Documentation](https://docs.newapi.pro/api/anthropic-chat)
14. Support for entering chat interface via /chat2link route
15. 🧠 Support for setting reasoning effort through model name suffixes:
    1. OpenAI o-series models
        - Add `-high` suffix for high reasoning effort (e.g.: `o3-mini-high`)
        - Add `-medium` suffix for medium reasoning effort (e.g.: `o3-mini-medium`)
        - Add `-low` suffix for low reasoning effort (e.g.: `o3-mini-low`)
    2. Claude thinking models
        - Add `-thinking` suffix to enable thinking mode (e.g.: `claude-3-7-sonnet-20250219-thinking`)
16. 🔄 Thinking-to-content functionality
17. 🔄 Model rate limiting for users
18. 💰 Cache billing support, which allows billing at a set ratio when cache is hit:
    1. Set the `Prompt Cache Ratio` option in `System Settings-Operation Settings`
    2. Set `Prompt Cache Ratio` in the channel, range 0-1, e.g., setting to 0.5 means billing at 50% when cache is hit
    3. Supported channels:
        - [x] OpenAI
        - [x] Azure
        - [x] DeepSeek
        - [x] Claude

## Environment Variable Configuration

For detailed configuration instructions, please refer to [Installation Guide-Environment Variables Configuration](https://docs.newapi.pro/installation/environment-variables):

- `GENERATE_DEFAULT_TOKEN`: Whether to generate initial tokens for newly registered users, default is `false`
- `STREAMING_TIMEOUT`: Streaming response timeout, default is 60 seconds
- `DIFY_DEBUG`: Whether to output workflow and node information for Dify channels, default is `true`
- `FORCE_STREAM_OPTION`: Whether to override client stream_options parameter, default is `true`
- `GET_MEDIA_TOKEN`: Whether to count image tokens, default is `true`
- `GET_MEDIA_TOKEN_NOT_STREAM`: Whether to count image tokens in non-streaming cases, default is `true`
- `UPDATE_TASK`: Whether to update asynchronous tasks (Midjourney, Suno), default is `true`
- `COHERE_SAFETY_SETTING`: Cohere model safety settings, options are `NONE`, `CONTEXTUAL`, `STRICT`, default is `NONE`
- `GEMINI_VISION_MAX_IMAGE_NUM`: Maximum number of images for Gemini models, default is `16`
- `MAX_FILE_DOWNLOAD_MB`: Maximum file download size in MB, default is `20`

## Deployment

For detailed deployment guides, please refer to [Installation Guide-Deployment Methods](https://docs.newapi.pro/installation):

> [!TIP]
> Latest Docker image: `calciumion/new-api:latest`

### Multi-machine Deployment Considerations
- Environment variable `SESSION_SECRET` must be set, otherwise login status will be inconsistent across multiple machines
- If sharing Redis, `CRYPTO_SECRET` must be set, otherwise Redis content cannot be accessed across multiple machines

### Deployment Requirements
- Local database (default): SQLite (Docker deployment must mount the `/data` directory)
- Remote database: MySQL version >= 5.7.8, PgSQL version >= 9.6

### Deployment Methods

#### Using BaoTa Panel Docker Feature
Install BaoTa Panel (version **9.2.0** or above), find **New-API** in the application store and install it.
[Tutorial with images](./docs/BT.md)

#### Using Docker Compose (Recommended)
```shell
# Download the project
git clone https://github.com/Calcium-Ion/new-api.git
cd new-api
# Edit docker-compose.yml as needed
# Start
docker-compose up -d
```

#### Using Docker Image Directly
```shell
# Using SQLite
docker run --name new-api -d --restart always -p 3000:3000 -e TZ=Asia/Shanghai -v /home/ubuntu/data/new-api:/data calciumion/new-api:latest

# Using MySQL
docker run --name new-api -d --restart always -p 3000:3000 -e SQL_DSN="root:123456@tcp(localhost:3306)/oneapi" -e TZ=Asia/Shanghai -v /home/ubuntu/data/new-api:/data calciumion/new-api:latest
```

## Channel Retry and Cache
Channel retry functionality has been implemented, you can set the number of retries in `Settings->Operation Settings->General Settings`. It is **recommended to enable caching**.

### Cache Configuration Method
1. `REDIS_CONN_STRING`: Set Redis as cache
2. `MEMORY_CACHE_ENABLED`: Enable memory cache (no need to set manually if Redis is set)
