Models

MahanAI Super supports multiple backends selectable at runtime via /models.

NVIDIA NIM

Pretty Name	Model ID	Backend
Llama 3.3 70B	meta/llama-3.3-70b-instruct	NVIDIA NIM (direct)

Note: A legacy server mode (mahanai/mahanai) exists in the model selector but is undocumented and not recommended for use.

Claude

Pretty Name	Model ID	Backend
Claude Opus 4	claude-opus-4-7	Claude CLI
Claude Sonnet 4.6	claude-sonnet-4-6	Claude CLI
Claude Haiku 4.5	claude-haiku-4-5-20251001	Claude CLI

OpenAI Codex

Seven models available, each accessible in Direct and Indirect mode (see OpenAI Codex below):

Pretty Name	Model ID
GPT-5.4	gpt-5.4
GPT-5.2-Codex	gpt-5.2-codex
GPT-5.1-Codex-Max	gpt-5.1-codex-max
GPT-5.4-Mini	gpt-5.4-mini
GPT-5.3-Codex	gpt-5.3-codex
GPT-5.2	gpt-5.2
GPT-5.1-Codex-Mini	gpt-5.1-codex-mini

Switch models interactively with /models (arrow-key selector) or quick-switch with /mode claude / /mode default.

/api-key clear	Remove saved server key
/api-key-nvidia [key]	Save NVIDIA direct API key
/api-key-nvidia clear	Remove NVIDIA key, switch back to server
/codex-login	Sign in to OpenAI via browser (Codex Direct mode)
/codex-logout	Remove saved OpenAI Codex credentials
/help	Show help
/exit or /quit	Leave

API Keys

Server / NVIDIA NIM

1. Environment: MAHANAI_API_KEY=...
2. Project .env: MAHANAI_API_KEY=...
3. In-app: /api-key your-key

Keys are stored under %APPDATA%\MahanAI\config.json on Windows or ~/.config/mahanai/config.json on Linux/macOS.

Claude CLI mode

Claude models use your local claude CLI installation. Make sure Claude Code is installed and on your PATH. No extra API key configuration needed inside MahanAI — it uses whatever account Claude CLI is authenticated with.

OpenAI Codex

MahanAI supports two Codex authentication modes:

Direct mode

Signs in to your OpenAI account via a browser-based OAuth PKCE flow — no API key needed.

/codex-login

This opens your browser to auth.openai.com. After you approve, MahanAI receives and stores the access token automatically. Tokens are refreshed silently before they expire (saved to the same config.json as other keys).

Indirect mode

Reads credentials from a locally installed and signed-in OpenAI Codex CLI. MahanAI looks for auth.json in these locations:

Platform	Paths checked
Windows	%LOCALAPPDATA%\OpenAI\Codex\auth.json, ~\.codex\auth.json
macOS / Linux	~/.codex/auth.json, ~/.config/codex/auth.json

If no token file is found, MahanAI falls back to running the codex CLI as a subprocess (requires Codex CLI on your PATH).

To use indirect mode, install and sign in to the Codex CLI first:

npm i -g @openai/codex
codex login

Then select any OpenAI Codex (Indirect) model from /models.

Environment Variables

Variable	Purpose
MAHANAI_API_KEY	Override saved server API key
MAHANAI_MODEL	Override default model ID
MAHANAI_STREAM	Set to 0/false/no/off to disable streaming
MAHANAI_CONFIG_DIR	Override config file directory
NO_COLOR	Disable terminal colors

Tools

MahanAI can execute tools on your behalf:

• run_command — run shell commands (asks confirmation before destructive ops)
• read_file — read a file
• write_file — write a file
• append_file — append to a file
• list_directory — list directory contents

Develop

pip install -e .
python -m mahanai

Publish to PyPI

Bump version in both pyproject.toml and mahanai/__init__.py, then:

pip install build twine
python -m build
python -m twine check dist/*

Windows (PowerShell):

$env:TWINE_USERNAME = "__token__"
$env:TWINE_PASSWORD = "pypi-YOUR_TOKEN_HERE"
python -m twine upload dist/mahanai-4.0.0*

macOS / Linux:

export TWINE_USERNAME=__token__
export TWINE_PASSWORD=pypi-YOUR_TOKEN_HERE
python -m twine upload dist/mahanai-4.0.0*

twine cannot publish without your token; keep it out of git.
