You.com combines open AI models and web search into a single API for enterprises.

You.com launches Inference Router, a single API connecting AI models like DeepSeek V4.1 Flash, Kimi K3, and GLM 5.3 with 99.9% SLA and web search integration.

Choosing an artificial intelligence model is no longer enough when an application needs to run continuously. Enterprise companies must also ensure that servers respond, that data is processed according to their security requirements, and that an outage at a provider does not interrupt their services. With Inference Router, You.com brings together multiple AI models behind a single API, combining U.S. hosting, built-in web search, and a contractual uptime commitment. In particular, the service provides access to models from DeepSeek, Moonshot AI, Alibaba, Z.ai, Meta, and Inception, without requiring a dedicated infrastructure contract to start using them. Open Models Scale to Enterprise Applications

Open-weight models now hold an important place in enterprise applications. Their use is no longer limited to experiments: they can handle document classification, information extraction, summarization, certain agentic reasoning steps, and a portion of coding tasks. Their inference cost can also be lower than that of the most powerful proprietary models, provided an architecture suited to each use case is selected.

However, this diversity creates new constraints. Developers must navigate multiple inference providers, different interfaces, varying privacy terms, and uptime guarantees that are not always equivalent. An application using multiple models can thus depend on distinct services, each with its own infrastructure and operational rules.

You.com aims to simplify this setup with a common access point. Inference Router provides an API compatible with OpenAI interfaces, allowing developers to preserve much of their existing code while primarily changing the service address and access credentials. Current documentation also describes an endpoint compatible with Anthropic’s Messages format.

Model selection remains independent of this infrastructure layer. A company can reserve a fast, cost-effective model for triaging operations, while using a higher-performing architecture for complex development or analytical tasks. DeepSeek, Kimi, GLM, and Mercury from a Single Interface

The Inference Router catalog brings together several families of models developed by different research labs. Announced offerings include Moonshot AI’s Kimi K3, DeepSeek V4.1 Flash, Z.ai’s GLM 5.3, Alibaba’s Qwen3.8 Flash, Meta’s Muse Spark 1.3, and Inception’s Mercury 3.

The selection also includes GLM 5.3 Flash, DeepSeek V4 Pro, Qwen3.8 Max, Muse Wonder, MiniMax M3, and GPT-OSS-120B. Reflection’s Beam model is listed among upcoming additions.

This lineup brings together models with different characteristics. Some are geared toward coding tasks and long-running agents, while others prioritize response speed or processing large request volumes. You.com does not offer a single model tasked with meeting all needs, but rather an infrastructure allowing teams to choose the model suited to a given application.

Models remain identified by their originating laboratory. Inference Router primarily provides hosting, execution, and unified access, featuring optimizations developed directly or in collaboration with select providers. An Infrastructure with Automatic Failover in Case of Incidents

Reliability relies on two execution tiers. Requests are first sent to You.com Inference Direct, the infrastructure operated by the company. When that capacity becomes unavailable or insufficient, the router can automatically route requests to selected partners.

You.com notably lists Parasail, Wafer, Alibaba Cloud, Meta, and Inception among its partners, with Prime Intellect announced for future integration. All providers used in this setup are presented as having U.S.-hosted capacity and complying with the privacy requirements enforced by the platform.

The company announces a service availability SLA of at least 99.9%, accompanied by service credits when applicable commitments are not met. Higher tiers can be negotiated for larger deployments.

This contractual guarantee does not mean that no interruptions can ever occur. It defines an expected level of availability as well as the compensations outlined in the service level agreement. Nor does it guarantee identical latency across all models or backup providers.

Automatic failover does, however, prevent an application from having to manually manage every provider change. You.com states that this mechanism does not alter the price billed for a request. A Data Retention Policy That Includes Web Search

The other component of the offering involves the processing of information sent to the models. You.com offers a Zero Data Retention (ZDR) policy applicable to both inference requests and web search calls.

According to the documentation dedicated to this policy, prompts and completions are processed in memory and deleted after the request is completed, without persistent storage of their content in service databases or logs. They are not used to train or fine-tune models.

The system does, however, allow the retention of certain metadata necessary for service operations, including token counts, timestamps, status codes, account identifiers, and billing details. ZDR therefore does not mean an absolute absence of data collection, but rather the absence of persistent storage of processed content within the defined scope.

You.com states that this policy also applies to failover partners. The company further announces fully U.S.-hosted infrastructure, spending controls per API key, daily visibility into usage, and the option to obtain a Data Processing Addendum (DPA) for Enterprise accounts.

These features apply to the commitments described by the provider. Companies subject to specific regulatory obligations will need to review contractual terms, subcontracting scopes, and exact processing conditions prior to any deployment. Integrated Web Search for Request Processing

Inference Router also builds on You.com’s history in web search. Models can leverage the platform's search engine to retrieve recent information without
