Not just routing. Intelligence.

7 analyzers, Guardian anti-loop protection, and multi-provider optimization — built for production.

< 1ms Smart Routing

7 analyzers detect intent, complexity, tools, and code in under a millisecond. No LLM call for routing — pure CPU.

Control Layer — Anti-drift

Baseline every agent, detect prompt inflation, silent escalations to premium models and pricing drift. Alerts, rollback, per-agent budgets. Built for CTOs who want total control of their LLM spend.

Guardian Anti-Loop

Real-time protection against invisible cost explosions. Detects health check loops, retry storms, context bloat, zombie agents.

Advanced Budget Controls

No LLM provider offers this. Set daily/monthly caps, per-model limits, off-hours rules, and automatic degradation.

Usage Reporting

Per-user CSV exports, daily breakdowns by model, token-level cost attribution. Plug it into your invoicing or your accounting in two clicks.

Multi-Provider Optimization

Anthropic, OpenAI, Google, Mistral, DeepSeek — picks the best price/quality across all your enabled providers.

1 Line Integration

Frequently Asked Questions

How does HiWay2LLM reduce my costs?
Most LLM requests don't need the most powerful (and expensive) model. A simple "hello" doesn't need Claude Opus at $15/M tokens — Haiku at $0.80/M handles it perfectly. HiWay2LLM analyzes every request in under 1 millisecond and routes it to the cheapest model that can handle it. You save 40-85% without changing your code or prompts.
Will the quality of responses decrease?
No. HiWay2LLM only routes simple requests (greetings, short questions, confirmations) to cheaper models. Complex tasks — code generation, multi-step reasoning, agentic tool use — still go to the most powerful models. You can also override routing at any time with the X-Force-Model header if you need a specific model for a request.
How long does it take to integrate?
About 2 minutes. You change one line of code — your base_url. That's it. HiWay2LLM is compatible with any LLM SDK: OpenAI, Anthropic, LangChain, Vercel AI SDK, n8n, curl, and anything that speaks the standard API format. No SDK to install, no config file to maintain.
What LLM providers are supported?
Anthropic (Claude Haiku, Sonnet, Opus), OpenAI (GPT-4o Mini, GPT-4o, GPT-4.1, o3), Google (Gemini Flash, Gemini Pro), Mistral (Small, Large), and DeepSeek (V3, R1). We automatically pick the best price/quality across all your enabled providers.
Do you store my prompts or responses?
No. Zero prompt logging is a core architectural principle, not just a policy. Your prompts pass through our routing proxy in memory only, are forwarded to the LLM provider, and immediately discarded. No prompt data is ever written to disk. We only store metadata: token counts, model selected, cost, and routing latency.
How does pricing work?
You buy credits upfront. $105 gives you $100 of LLM credits (5% platform fee included). Credits are deducted in real-time at the exact price the LLM provider charges — no markup. Credits never expire. You can check your balance anytime in the dashboard.
What is the Guardian anti-loop system?
Guardian monitors your LLM traffic and detects patterns that silently burn your budget: health check loops, retry storms, context bloat (prompts growing to 100K+ tokens), zombie agents running at 3am, and cost spikes. Each rule is toggleable — you set the thresholds. It's like guardrails for your LLM spending.
What if HiWay2LLM goes down?
We target 99.9% uptime. If our routing proxy is unavailable, your requests will fail with a clear error (502). We recommend implementing a simple fallback in your code that routes directly to your provider if HiWay2LLM is unreachable. This takes 3 lines of code.
Can I force a specific model for certain requests?
Yes. Add the X-Force-Model header to any request to bypass smart routing. For example: X-Force-Model: claude-opus will always use Opus regardless of the complexity score. Useful for critical requests where you always want the best model.
Is this GDPR compliant?
Yes. We're a French company (Mytm-Group SAS) hosted on EU servers (OVH, France). We don't store personal data beyond your email. We don't store prompts. We comply with GDPR and the EU AI Act. A Data Processing Agreement (DPA) is available for enterprise clients.
How does this compare to OpenRouter?
OpenRouter is a multi-provider API gateway — you manually choose which model to use. HiWay2LLM is a smart router — it automatically picks the best model for each request based on complexity analysis. OpenRouter adds cost (their fee + no routing savings). HiWay2LLM saves cost (routing to cheaper models offsets the 5% fee).
Can I self-host HiWay2LLM?
We offer a fully managed SaaS — no infrastructure to maintain. For enterprise clients with specific compliance or data residency requirements, we offer private deployment options. Contact us to discuss.
