sarvam-cli 0.1.0

Developer-first command-line interface for Sarvam AI.

Sarvam CLI

Agent-style terminal interface for Sarvam AI.

Sarvam CLI brings chat, voice, translation, transcription, language detection, and speech generation into a clean terminal workflow. It is designed to feel closer to a modern coding agent CLI than a thin API wrapper.

Why

Sarvam has strong multilingual and speech APIs, but quick experimentation usually means writing setup code first. Sarvam CLI removes that setup friction:

• talk to Sarvam directly from the terminal
• test speech and translation flows without boilerplate
• switch between text, voice, and file-based workflows quickly
• keep per-user config local and simple

Highlights

• Guided home screen with onboarding
• Interactive chat workspace with boxed composer flow
• Voice chat using microphone input and spoken replies
• Speech-to-text for audio files
• Translation for file or stdin input
• Text-to-speech with file output
• Language detection
• Per-user config with env-var overrides

Installation

Basic install:

pip install sarvam-cli

With voice support:

pip install "sarvam-cli[voice]"

For local development from this repo:

python -m venv .venv
source .venv/bin/activate
pip install -e .

Quick Start

1. Set your API key:

sarvam config set-api-key

2. Open the CLI:

sarvam

3. Start chatting:

Configuration

Sarvam CLI stores user config at:

~/.config/sarvam/config.json

Useful commands:

sarvam config set-api-key
sarvam config set-base-url https://api.sarvam.ai
sarvam config show
sarvam config path

Environment variables are also supported:

export SARVAM_API_KEY=your_api_key
export SARVAM_BASE_URL=https://api.sarvam.ai

For one-off overrides:

sarvam --api-key your_api_key chat "Hello"
sarvam --base-url https://api.sarvam.ai chat "Hello"

You can override the config directory too:

export SARVAM_CONFIG_DIR=/custom/path
