Token optimization for AI coding
UsageX reduces input and output tokens and routes every request to the right model — so your subscriptions last longer and your API bill shrinks. No quality loss.

quality loss. Fewer tokens, same results — that's the whole point.
Input and output token reduction plus smart model routing, built into everything we ship.
Stretch your Codex and Claude pro subscriptions with token reduction and model routing. Two $20 pro plans with Limit Extender beat one $100 Max plan.

Maximum savings. Every task goes to the cheapest model that can handle it, with aggressive token reduction. Perfect for day-to-day coding where speed and cost matter most.
Maximum capability. Hard problems get the strongest models — Opus Planner for architecture and debugging — while easy sub-tasks still route cheap. Big-brain results without a big-brain bill.
Maximum polish. Routing tuned for UI and frontend work: models that excel at layout, styling and visual detail handle your interface, pixel by pixel.
We maintain a 5TB library of code. Instead of generating everything from scratch, we cut and paste from it — the AI only writes what's missing. That means far fewer output tokens for the same result.
Proven code is retrieved and reused instead of regenerated, so the model only produces the parts that don't exist yet.
Prompts and responses are trimmed to what actually matters, cutting tokens on both sides of every request.
Each request goes to the cheapest model that can handle it — heavy models only when they're truly needed.
The same work, side by side.
| Without UsageX | With UsageX | |
|---|---|---|
| Output tokens | Everything generated from scratch | Cut & paste from a 5TB library — AI only writes what's missing |
| Model choice | One model for everything, easy or hard | Routed per task: Codex Luna → Sonnet → Opus Planner |
| Subscription cost | $100/month for one Max plan | Two $20 pro plans + Pro ≈ $57/month, more capacity |
| Hitting limits | Watching the usage bar, waiting for resets | Never hit your limits again |
| Quality | Baseline | Identical — 0% quality loss |
Because most code you need already exists. We keep a 5TB library of proven code and cut and paste from it — the model only generates the parts that are genuinely new. Fewer tokens generated doesn't mean less code delivered.
Every task is classified first. Easy tasks (boilerplate, small edits) go to Codex Luna, everyday coding goes to Sonnet, and the hardest planning and debugging goes to Opus Planner. You get heavy-model quality only where it matters — and cheap speed everywhere else.
Limit Extender stretches your subscription plans (Codex and Claude pro plans), so you never hit your limits again. API Optimizer applies the same token reduction and routing to pay-per-token API usage, shrinking your API bill.
Yes. Two $20 pro plans plus Limit Extender Pro ($16.99 excl. VAT) is about $57/month — with more combined capacity than one $100 Max plan.
Pricing is coming soon. Limit Extender is available today, starting at $7.99/month (excl. VAT).
