One OpenAI-compatible key for discounted GPT, Claude and Gemini access
The catalogue spans over 90 models across LLMs, image, video, audio and embedding endpoints, individually priced per million tokens.
Each listed provider passes an LLM fingerprint test intended to confirm you receive the exact model you paid for, with no silent substitution.
If a routed channel goes down, requests are automatically routed to the next verified provider, so production calls keep running without manual key rotation.
Use one key and one prepaid balance across every model, with an OpenAI-compatible base URL for tools like Cursor, LangChain and LiteLLM.
Intelligent model routing for coding agents
Predicts the best model and reasoning effort for each step of a session by weighing prompt semantics, cache state, sub-agent structure and past session outcomes.
Works alongside the coding-agent harness and model gateway you already use, so recommendations execute inside your own stack without locking you into a single provider.
Can route using only derived request metadata and locally computed features, so Not Diamond never sees your payloads, inputs or outputs.
Reinforcement learning from feedback signals and session results personalizes recommendations per developer and transfers learnings across an organization.
