Description
LowRouter serves as a European AI gateway designed for agents and applications, offering a single API key and a consolidated bill in euros for language models sourced from both European and global providers. Users can establish routing rules tailored to each API key, allowing for options such as exclusive use of EU-sovereign providers, routing that prioritizes lower carbon emissions, cost-effective routing, or any combination thereof. The responses generated include details about the provider and its region, along with an estimated carbon footprint when the model's data allows for such reporting.
Coding agents like OpenCode, Claude Code, and Cline have the option to utilize LowRouter as a custom provider, while applications developed with LangChain or the OpenAI SDK can also integrate seamlessly. With the use of aliases, switching between models or providers can be accomplished without modifying the underlying code, and the automatic routing feature ensures that eligible requests are redirected to alternate providers in the event of a route failure.
Users can explore the public model catalogue, which is searchable by factors such as sovereignty and carbon intensity. Billing for tokens is done at the rates set by providers without any additional per-token markup; however, there are fees associated with credit top-ups, and the service does not require a subscription. LowRouter is managed by Carbonifer SAS, which is based in Nantes, France, ensuring a dedicated focus on both sustainability and user-friendly access. Additionally, the platform is continuously evolving to meet the needs of its users in a rapidly changing technological landscape.
Description
Vercel AI Gateway is a centralized AI model routing and infrastructure platform designed to help developers build, deploy, and scale AI-powered applications using a single unified interface for multiple AI providers and models. The platform enables developers to access text, image, and video generation models from leading AI labs including OpenAI, Anthropic, xAI, and other providers through one API endpoint, one authentication layer, and one management dashboard. AI Gateway simplifies AI application development by consolidating model routing, usage monitoring, billing, failover management, and observability into a single system, eliminating the need to integrate separately with multiple AI vendors. Developers can use the Vercel AI SDK or OpenAI-compatible APIs to build AI applications with support for streaming responses, stateful agents, multimodal generation, tool calling, and conversational workflows. The platform includes built-in resiliency features such as automatic provider failovers and workload routing to maintain uptime during outages or degraded model performance. AI Gateway also provides unified cost tracking and transparent billing with no markup over provider pricing, helping teams monitor AI usage across applications and providers more effectively. In addition to text generation, the platform supports image generation and editing workflows, as well as production-ready AI video generation capabilities accessible through prompt-based interfaces. Integrated developer tooling, SDKs for multiple programming languages, authentication management, and deployment workflows make Vercel AI Gateway particularly suited for modern web applications, AI agents, SaaS platforms, and developer-focused AI products.
