Continuous optimization
Between your orchestrator and your models. Running locally in Brazil.
Output assembly
PII redaction, transcripts, and analytics. All processing local. Your provider is only called when the cache can't answer.

Execution layer in Brazil
Keep your pipeline. Add the execution layer
Continuous cost and latency reduction.
Keep your orchestrator
Livekit, Pipecat, custom. Your application code stays the same.
Keep your LLM
Keep your existing model and provider. SLNG routes, caches, and reduces cost on every call.
Keep your STT & TTS models
Bring your existing contract and provider. Or choose from SLNG 30+ model catalogue.
Getting started
Live instantly. Results within 24hrs
Send your existing call flow. We run it locally in Brazil and show you the numbers against your current setup.
1. Add your keys
Bring your own keys for STT, LLM, and TTS. We never see your credentials.
2. Point to SLNG //
Direct your orchestrator to SLNG endpoints for STT, LLM, and TTS.
3. See the results
Give it 24 hours. Your dashboard shows savings, latency, and quality vs. baseline.
Can I bring my own model API keys?
Yes. BYOK is the default. Bring your existing OpenAI, Anthropic, Deepgram, or ElevenLabs keys. The SLNG Execution layer routes through them, adding routing, caching, and observability without changing your provider contracts.
Is SLNG suitable for regulated environments?
Yes. SLNG enforces region and country rules at runtime. Enterprise plans add residency, retention, auditability, and SLA-backed guarantees for regulated workloads.
How much does SLNG cost in Brazil?
US$ 0.0033 per agent minute for the execution layer. Add STT or TTS for US$ 0.0033 each. No contracts. No minimums.
Is SLNG HIPAA compliant?
Yes. SLNG is HIPAA compliant with BAA available. ISO 27001 certified. SOC 2 Type II in audit. Details at trust.slng.ai.
What is the SLNG Execution layer?
The infrastructure between your orchestrator and your models. It routes each call to the right model, caches repeated patterns, redacts PII, cancels noise, and logs everything: cost, latency, region, provider, per step. You keep your existing code. SLNG handles the layer underneath.
What voice AI models does SLNG support?
30+ models across STT, LLM, and TTS, including Deepgram, Whisper, OpenAI, Anthropic, Rime, Cartesia, and ElevenLabs. Sovereign-hosted models run on SLNG's own in-region compute. BYOK is the default - bring your existing provider keys and contracts.
Does SLNG work with my agent platform?
If it has a custom LLM field or accepts an OpenAI-compatible endpoint, yes. ElevenLabs, Deepgram, Vapi, Vocode, Bolna, Voiceflow confirmed.
How does SLNG reduce voice AI latency?
The execution layer routes each call to the optimal model based on cost and latency, adding under 2ms of overhead. And sovereign hubs run the full stack on physical hardware in 11 regions so your models and your callers are in the same region. Observed result: ~39% less turn latency in production.
