Compress LLM prompts with one REST API call and cut token costs
Send your prompt to a single REST endpoint and receive a shorter version back as plain text, ready to pass to your model.
The vendor reports up to 40% lower LLM input cost, with a worked example showing a 45% reduction on a sample prompt.
Copy-paste examples are provided for curl, Python, JavaScript and C#, so integration takes minutes rather than days.
Wrap sections in tags to exclude them from compression or to set a specific compression ratio for that block.
Representation engineering that gives you real control over AI models
Modify how a model represents and processes information internally, gaining control that prompt engineering cannot achieve without full retraining.
Target unreliable or fabricated output by steering model representations, improving trustworthiness for production applications.
The company highlights gains in coding and math ability, positioning the layer as a capability upgrade rather than only a safety filter.
Integrate with a clean interface in just a few lines of code and add representation engineering to applications without lengthy training pipelines.
