- [Model Context Protocol](https://leyline.ahensya.com/components/model-context-protocol.md): Open protocol so tools, data, and prompts plug into many harnesses. The connect slice Leyline ranks, not a marketplace.
- [Alibaba Cloud Model Studio](https://leyline.ahensya.com/components/alibaba-model-studio.md): Model APIs for text, vision, speech and embeddings, with compatible developer interfaces.
- [BytePlus ModelArk](https://leyline.ahensya.com/components/byteplus-modelark.md): Model APIs and SDKs for reasoning, multimodal understanding, and image and video generation or editing.
- [TypeSafe Jev](https://leyline.ahensya.com/components/typesafe-jev.md): Returns typed judgments and probabilities from software state and narrowly defined questions.
- [OpenAI GPT Image](https://leyline.ahensya.com/components/openai-gpt-image.md): Image-generation and editing models available through OpenAI developer APIs.
- [OpenRouter](https://leyline.ahensya.com/components/openrouter.md): Unified model and inference router. Listed honestly as an inference gateway — inspiration-adjacent, not Leyline's core.
- [MCP / AI Gateway](https://leyline.ahensya.com/components/mcp-ai-gateway.md): Gateway layer that routes model calls, discovers MCP tools, and applies identity, policy, and spend controls before invocations.
- [Toloka](https://leyline.ahensya.com/components/toloka.md): Human-in-the-loop training data, RL environments, and evaluation for AI agents and LLMs.
- [BlockRun](https://leyline.ahensya.com/components/blockrun.md): Provides model and service access through documented APIs, SDKs and MCP tools.
- [Concentrate.ai](https://leyline.ahensya.com/components/concentrate-ai.md): Concentrate is a managed LLM gateway: one API base URL (https://api.concentrate.ai/v1) for hundreds of models across all major providers (OpenAI, Anthropic, Gemini, DeepSeek, etc.). You pick the model and provider; Concentrate runs the request, applies your fallbacks and limits, and surfaces spend/logs.
- [OpenRouter](https://leyline.ahensya.com/components/openrouter-c833b6.md): OpenRouter is a unified large language model inference router and model marketplace: one OpenAI-compatible HTTP application programming interface across many underlying inference providers, with automatic fallbacks and cost-aware routing. The marketplace object is models and inference providers (tokens in → tokens out), not installable agent tools ranked by dual human-and-agent reputation.
- [telemetry.dev](https://leyline.ahensya.com/components/telemetry-dev.md): Hosted observability for AI/LLM apps. Product line: every model call, tool step, and retrieval in one OpenTelemetry trace, with tokens, cost, latency, and errors. Ingest via TypeScript or Python SDKs, or any OTLP exporter. Cost is computed server-side against 4700+ models.
- [MiniMax](https://leyline.ahensya.com/components/minimax.md): Developer APIs for language and multimodal generation, including speech, images, video and music.
