免费 / 开源以极低成本提供出色的开源权重推理性能,但缺少 BigModel 广泛的企业级多模态智能体构建工具集。

Itzam is an open-source backend for AI applications that unifies model access, prompt management, retrieval context and spend tracking behind a single SDK and dashboard. Instead of stitching together separate providers for RAG, observability and billing, teams connect their documents and prompts once and switch models without rewriting integration code.

Itzam is an open-source backend for AI applications that unifies model access, prompt management, retrieval context and spend tracking behind a single SDK and dashboard. Instead of stitching together separate providers for RAG, observability and billing, teams connect their documents and prompts once and switch models without rewriting integration code.
Store documents and knowledge as named 'context slugs' that the platform indexes and retrieves, so RAG pipelines no longer need custom vector-store plumbing.
Change the active model or system prompt instantly from the dashboard; the live slug keeps working so you can test new models without a deploy.
Built-in request logs show status, model, input, per-call cost and latency for every generation, making debugging and load testing straightforward.
Aggregate spend across OpenAI, Anthropic and Google in one view, broken down by provider, model, requests and tokens.

OrcaRouter is an OpenAI-compatible AI gateway that grades every prompt and routes it to the best-value model, then layers on failover, guardrails, an agent firewall, and compliance tooling for production AI.

Replicate is a cloud API for running, fine-tuning, and deploying machine learning models. Spin up open-source and hosted models — from image, video, and audio generation to speech synthesis, captioning, and LLM inference — with one line of code, or package your own model with Cog and put it behind a production-ready API.
