Baseten

Baseten is a production inference platform for deploying, serving, and scaling ML and generative AI models. Developers package models with the open-source Truss tool and deploy to autoscaling GPU infrastructure with fast cold starts, observability, and dedicated options. It targets teams with real production traffic that need reliable, low-latency inference on open or custom models.

Baseten is a production inference platform for teams that need to deploy and scale their own models rather than only call a shared API. Developers package models with Truss, Baseten's open-source model-packaging framework, and deploy them to autoscaling GPU infrastructure with fast cold starts, monitoring, and observability. It supports both open-source models and custom or fine-tuned models across language, image, audio, and other modalities. The platform targets the application layer of AI: companies building products that depend on reliable, low-latency inference and want performance engineering, autoscaling, and multi-cloud or dedicated capacity without building it themselves. Baseten emphasizes inference optimization, dedicated deployments for demanding workloads, and enterprise features like security and support. Baseten has grown rapidly and raised large late-stage rounds through 2025 and 2026 as inference demand surged. It suits teams with real production traffic and specific model or performance requirements more than casual experimenters, and pricing reflects usage of GPU compute, so cost modeling matters for high-volume deployments.
