Cactus

Routing to On-Device
Auto-optimizing for accuracy & cost

Cactus Hybrid Cloud
Cloud accuracy. Without the cloud cost.

Cactus only hands off the complex requests to the cloud, running simple tasks on-device.

import os
from src.cactus import cactus_init, cactus_complete
os.environ["CACTUS_CLOUD_KEY"] = "your-api-key"
model = cactus_init("weights/qwen3-600m", None, False)
result = cactus_complete(model, messages, None, None, None)
5x
Cost Savings

Over 80% of production transcription and LLM inference can be handled on-device.

<120ms
On-Device Latency

Real-time transcription. No round-trip to the cloud for clear audio.

Native
Optimized for every platform

We built Cactus as an on-device engine first. Optimized for the fastest inference on smartphones, laptops, and wearables.

Automatic Handoff

Cactus monitors audio quality in real-time. When conditions change, we seamlessly switch between on-device and cloud inference. Your app doesn't need to know the difference.

Privacy When You Need It

For sensitive applications, lock transcription to on-device only. Audio data never leaves the user's phone. HIPAA-friendly, GDPR-compliant, zero data retention.

Simple pricing.
Start free, scale as you grow.

No hidden fees. No surprises. Just inference that works.
