Prompt management, evaluation, and guardrails for production LLM apps
Build, test, and version prompts in a table-based editor that anyone comfortable with spreadsheets can use.
Add natural-language assertions, pattern matching, or custom code checks and run them over datasets to catch regressions.
Trace every request and response, inspect latency and cost, and diagnose why an LLM answered the way it did.
One-click AI Firewall blocks prompt injection, denial-of-service attempts, and information leaks with customisable content filtering and alerts.
Run and build with open AI models locally or in the cloud
Install once and pull open-weight models by name; Ollama handles weights, quantization and versioning for you.
A built-in server exposes a straightforward REST API, so scripts, editors and agents can talk to local models with minimal setup.
Route requests to hosted open models when your laptop cannot hold the checkpoint you need, with per-token pricing and concurrency tiers.
Access families such as Llama, Qwen, DeepSeek, Gemma, Mistral and gpt-oss from a single interface.
