Stop overpaying for AI. SwarmSync analyzes every request in real time — prompt complexity, task type, context length — and routes it to the best model at the lowest cost. Simple chat goes to a $0.03/M model. Hard reasoning goes to Opus. You never think about it.
Definition block
A request router that selects the best model for the task while keeping spend under control.
SwarmSync scores task type, prompt complexity, and context pressure, then routes work to the best model and tier instead of defaulting to a single provider.
Vendor Lock-In
You pick one provider, hardcode the SDK, and pray they don't raise prices. Switching costs weeks of engineering. You're stuck.
Wasted Spend
Sending "What's 2+2?" to GPT-5.2 Pro at $21/M tokens is like taking a private jet to the corner store. 80% of requests don't need a premium model.
No Specialization
Claude excels at coding. Gemini dominates long context. Grok leads on tool use. No single model wins everything — but you're only using one.
Every request passes through a two-stage analysis pipeline before a single token is generated. No rules to configure. No model to select. It just works.
We analyze prompt length, code presence, reasoning keywords, tool calls, conversation depth, and context pressure to produce a complexity score (0.0 – 1.0). This determines the price tier: Economy, Mid, or Premium. Simple "hello" messages score 0.1. Multi-step code architecture prompts score 0.9.
Within the selected tier, we detect what your request actually needs — coding, reasoning, creative writing, structured output, long context, tool use, multilingual, or conversation — then compute a dot-product between detected task weights and each model's strength scores to pick the highest-scoring match. Ties broken by price.
From $0.03/M tokens to $21/M tokens. Every model profiled across 8 capability dimensions. Your request always lands on the right one.

We don't just pick the cheapest model. We pick the best model for what you're actually doing, within your budget tier.

Change two lines. Keep your entire codebase. SwarmSync's routing endpoint is fully OpenAI-compatible — same request format, same response schema, same streaming protocol.
// Before: locked to one provider const client = new OpenAI({ apiKey: OPENAI_KEY }); // After: every model, one key const client = new OpenAI({ apiKey: "sk-ss-...", baseURL: "https://swarmsync-api.onrender.com/v1" }); // model: "auto" → SwarmSync picks the best model // model: "anthropic/claude-opus-4-6" → force a specific model // model: "swarmsync/budget" → force economy tier
autoSmart routing. Complexity score determines tier, capability matching picks the model.
swarmsync/budgetForce economy tier. Ideal for high-volume, low-complexity workloads.
swarmsync/balancedSame as auto. Complexity-based routing for general use.
swarmsync/performanceForce premium tier. When accuracy matters more than cost.
Other routers just forward requests. We analyze your prompt in real time across 7 signal dimensions to score complexity before routing. The model selection is genuinely intelligent — not random, not round-robin.
Every model is scored across coding, reasoning, creative writing, structured output, long context, conversation, tool use, and multilingual. We match your task profile against model strengths via dot-product scoring.
Set daily and monthly spend caps. If you're approaching your limit, we automatically downgrade to economy tier to keep you running — no silent failures, no surprise bills.

60 req/min, 1,000 req/hr per API key. Sliding window enforcement protects your wallet and our infrastructure. One compromised key can't take down the platform.
Real-time analytics showing exactly how much you saved vs. sending everything to the most expensive model. Most users see 60-85% cost reduction on day one.
Pay the model provider's cost + 8% SwarmSync fee. That's it. No subscriptions, no minimums, no hidden markup. Top up your wallet with Stripe and start routing.
