FlexAI provides managed AI infrastructure for developers and teams building applications and AI agents. Its Token Factory offers access to more than 30 open-weight models through a single OpenAI-compatible API, supporting tasks such as text generation, coding, vision, embeddings, image generation, and speech. Users can test models in an ungated browser playground or connect existing applications using the OpenAI SDK.

The platform is designed to support projects as they grow, from usage-based serverless inference to dedicated GPU endpoints and private AI cloud deployments. FlexAI also offers AgentOS, which helps teams run agents with tools, scoped memory, approvals, model routing, and audit trails. Fine-tuning, training, and AI Factory deployment options extend the platform for more specialized needs, including VPC, on-premises, and air-gapped environments.

FlexAI highlights transparent, usage-based pricing for serverless services and GPU-hour pricing for dedicated endpoints. Its infrastructure includes NVIDIA and AMD GPU fleets, with an uptime SLA of up to 99.9%. The company also offers a startup program with credits for accepted applicants.
