04 / Questions
What is Prism? #
Prism is an OpenAI- and Anthropic-compatible inference API for coding agents. It serves open-weight frontier models so you can run the primary agent loop without standing up your own GPU stack.
Which models can I call? #
The public lineup is DeepSeek-V4.1-Flash, DeepSeek-V4-Flash, GLM-5.3, Kimi K3, Qwen3.8, and Qwen. Currently available model ids are deepseek-v4.1-flash, deepseek-v4-flash, glm-5.3, kimi-k3, qwen-3.8, and qwen.
Which API formats are supported? #
Prism supports OpenAI Chat Completions at https://api.prisminference.com/v1 and Anthropic Messages at https://api.prisminference.com. Keep your existing client and change the base URL, API key, and model id.
How do I get an API key? #
Create a Prism account, then create an API key from your account settings. Store it as PRISM_API_KEY and send it with your requests.
How is inference priced? #
Usage is billed per token. There is no per-seat fee. See Pricing for serverless, elastic, dedicated, and batch options.
Which coding agents work with Prism? #
Any client or gateway that can send OpenAI Chat Completions or Anthropic Messages, including Cursor, Claude Code, and configurable custom loops. Clients that require the OpenAI Responses API need a compatibility gateway.
Does Prism retain prompts or train on them? #
No. Prism applies strict zero data retention to API inputs and outputs and never uses them for training. See the Privacy Policy for details.
Can I get a private deployment? #
Yes. Book a call for dedicated capacity in our cloud or yours. 05 / Get a key
