Local actions.
Cloud reasoning.

On-device AI agents with cloud fallback.

Cactus routes agent commands based on complexity: on-device for simple tasks, cloud for complex operations.

Cactus Hybrid Cloud
Cloud accuracy. Without the cloud cost.
Cactus only hands off the complex requests to the cloud, running simple tasks on-device.
#include <cactus.h>
setenv("CACTUS_CLOUD_API_KEY", "your-api-key", 1); // optional hybrid cloud key
cactus_model_t model = cactus_init("path/to/weights");
char response[4096];
cactus_complete(model, messages, response, sizeof(response), nullptr, nullptr, callback);

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.
