Supported LLM APIs
The agent harness is agnostic to the LLM API protocol and provider. Skiller connects the harness to LLM providers through adapters.
Supported integrations
Section titled “Supported integrations”The following table summarizes the supported adapters, their APIs, and providers:
| API | Adapter | Providers |
|---|---|---|
| OpenAI-compatible Chat Completions | openai |
MiniMax, Moonshot, DeepSeek, OpenRouter, LM Studio, and compatible endpoints |
| Codex Responses | codex |
OpenAI Codex |
| Amazon Bedrock Converse | bedrock |
Models available through Amazon Bedrock |
Codex support uses its dedicated authentication and transport; it does not imply general support for arbitrary OpenAI Responses endpoints. OpenAI-compatible endpoints must support the request features used by your agent, including tool calls when tools are enabled.
Configure your providers
Section titled “Configure your providers”Use Add an LLM provider to authenticate from STUI.
See User LLM providers for your configured catalog, credentials, and models, or Custom providers to define another connection using a supported adapter.
