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

Execution layer in Finland
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 Finland 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.
What are SLNG's Nordic GPU hubs?
SLNG runs sovereign GPU hubs in Sweden (Stockholm) and Finland (Mäntsälä). Self-hosted STT and TTS models run locally on Nordic GPUs. The full EU model catalog is also available via proxy routing.
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.
Does my data leave the EU?
No. Routing enforces data residency at the infrastructure level. Audio stays in the EU.
Is SLNG compliant with GDPR?
GDPR compliant. ISO 27001 and SOC 2 Type II certified. HIPAA compliant. 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.
