Independent · aligned with your wallet

AI labs profit when
you spend more tokens.
We don't.

AI labs have every economic incentive to maximize your token usage. Nobody is pushing back — until now. SuperLeanAI is an independent third party with one job: make sure you spend as few tokens as possible. We only make money when you save money.

Every request bleeds tokens —
by design

Agents like Claude Code sends lots of information (10+ tool definitiones) on every LLM call. The labs have no incentive to make them short.

✗ BEFORE — original Bash tool 4,839 chars · ~1,210 tokens

  "name": "Bash",
  "description": "Executes a given bash command with optional
  timeout. Working directory persists between
  commands; shell state (everything else) does not.
  The shell environment is initialized from the
  user's profile (bash or zsh).

  IMPORTANT: This tool is for terminal operations
  like git, npm, docker, etc. DO NOT use it for
  file operations (reading, writing, editing,
  searching, finding files) — use the specialized
  tools for this instead.

  Before executing the command, please follow
  these steps:

  1. Directory Verification:
     - If the command will create new directories
       or files, first use `ls` to verify the
       parent directory exists ...

  2. Command Execution:
     - Always quote file paths that contain spaces
       with double quotes ...
  [... 4,500 more characters of instructions ...]",

Three things happen on every request

SuperLeanAI is a transparent HTTP proxy. Point your agent's BASE_URL to v1.superleanai.com (e.g. via ANTHROPIC_BASE_URL) and you're done.

✂️
STEP 01

Tool definition debloat

Verbose, multi-paragraph tool descriptions are summarized to a single sentence. The model still understands the tool — it just costs 92% less to say so.

🚫
STEP 02

Tool filtering & blocking

Block tools your agent doesn't really need (e.g. NotebookEdit, Grep). Or use agressive bash_only mode: strip everything down to just Bash, Read, and Edit — the minimum set for most coding tasks.

🔀
STEP 03

On the fly model switching & routing

Override the model on the fly — swap Opus for Sonnet during bulk tasks, or route different profiles to cheaper models without touching agent code.

Everything your agent bill needs

Built as a production-grade proxy with JWT auth, per-session stats, and live savings.

📊

Per-session savings tracking

Every session gets live stats: original tool bytes, debloated bytes, total traffic, and percentage saved. Know exactly what you're not paying for.

🔌

Multi-backend routing

Route to OpenRouter, Google Gemini (via googleapis), Groq, or Together AI. Configure named profiles — groq, googleapis_minimal — with different strategies per use case.

🗂️

Traffic logging

Every request is saved to disk as JSON. Replay, audit, or analyze your agent's traffic. Tool calls from the response are also captured for future debloating.

🔧

Drop-in compatible

Speaks the Anthropic /v1/messages API. Works with Claude Code, custom agents, any client targeting the Anthropic SDK. No code changes required.

Running in 3 commands

Point your agent to the proxy, and start saving. Works with Claude Code, Codex, your own agent, whatever.

For Claude Code, set ANTHROPIC_BASE_URL in your environment or .claude/settings.json to https://v1.superleanai.com/lean.

# Point your agent at the proxy
$ export ANTHROPIC_BASE_URL=https://v1.superleanai.com/lean
$ export ANTHROPIC_AUTH_TOKEN=your-superleanai-jwt-token
 
# 3. Run your agent as usual
$ claude "refactor auth module"
✓ session savings: 17.3% vs baseline

We win when you save.

Our incentives are completely aligned with yours. We take a small cut of the savings — if you don't save, you don't pay. Crystal clear, no subscription traps.
