# smolsi > smolsi is a complete local inference system from Happiest Labs: an in-house engine, document index, tools, and workers running on hardware the customer owns. It supports air-gapped agent workflows and annual licensing per seat or node, without per-token metering. Local model families include Qwen, Llama, DeepSeek, Mistral, Gemma, Kimi, and gpt-oss. Qwen is certified for the current release; additional families require certification before deployment. Workstation and shared-node configurations are available; private clusters are in early access. Public inference API, MCP, and agent-framework integration documentation is not published on this site. ## Product guide - [Overview and inference stack](https://smolsi.com/index.md#the-inference-stack): The components of the local system. - [Air-gapped agent workflows](https://smolsi.com/index.md#air-gapped-agent-workflows): Local documents, delegated work, host computation, and results for review. - [Models and capabilities](https://smolsi.com/index.md#models-and-capabilities): Model family coverage and certification, chat and vision, document indexing, and workbook tools. - [Deployment and licensing](https://smolsi.com/index.md#deployment-and-licensing): Availability, hardware sizing, and annual licenses. - [Privacy and deployment controls](https://smolsi.com/index.md#privacy-and-deployment-controls): Private source files, offline operation, and security-review documentation. - [Compliance and assurance](https://smolsi.com/index.md#compliance-and-assurance): HIPAA, SOC 2, GDPR, ITAR, CMMC, GLBA, and NIS2; supporting documentation and applicable scope are available during security review. - [Integration availability](https://smolsi.com/index.md#integration-availability): What this website currently documents for developers and agents. - [Evaluation and contact](https://smolsi.com/index.md#evaluation-and-contact): Evaluate a workflow with the engineering team. ## Website and company - [Machine view](https://smolsi.com/ai): The product guide rendered for reading in a browser. - [smolsi](https://smolsi.com/): The visual product overview. - [Agent workflows](https://smolsi.com/#agents): The website's agent workflow section. - [Compliance and assurance on the website](https://smolsi.com/#compliance): The compact credential overview and security-review contact. - [Happiest Labs](https://happiestlabs.ai): The company behind smolsi.
