Baseten
Production ML infrastructure — deploy any model with custom serving, autoscaling, and GPU selection
Baseten is a production ML infrastructure platform for deploying custom and open-weight models with full control over serving configuration, GPU selection, autoscaling, and cold-start behavior. Unlike managed inference APIs, Baseten lets you bring your own model weights, custom preprocessing, and serving logic. It supports Truss (Baseten's open-source model packaging format), vLLM, TensorRT-LLM, and custom Python serving code. Ideal for teams that need more control than a managed API but less overhead than raw Kubernetes.
Z.AI
GLM-5.3 frontier model with 1M context — available on Amazon Bedrock
Z.AI (formerly Zhipu AI) develops the GLM series of large language models. GLM-5.3 is the latest generation, supporting a 1M token context window and designed for enterprise-grade chat, coding, and long-document tasks. GLM-5.3 is now available on Amazon Bedrock, expanding its reach to AWS enterprise customers.

Z.AI
Key differentiators
The production ML platform that gives you managed-API convenience with custom-serving flexibility — deploy any model with your own preprocessing logic, GPU selection, and autoscaling without managing Kubernetes.
GLM-5.3 offers a 1M token context window at competitive pricing, now available on Amazon Bedrock — making it accessible to AWS enterprise customers without additional API integrations.
Frequently asked questions
Baseten FAQs
What is Baseten?
Baseten is a production ML infrastructure platform for deploying AI models with custom serving logic, GPU selection, and autoscaling. It supports any open-weight model or custom fine-tune via the Truss packaging format.
How does Baseten differ from Together AI or Replicate?
Baseten gives you full control over the serving stack — custom preprocessing, postprocessing, GPU selection, and autoscaling behavior. Together AI and Replicate are managed APIs with fixed serving; Baseten is for teams that need custom model serving logic.
What GPUs does Baseten support?
Baseten supports H100 SXM, H100 PCIe, A100 80GB, A10G, and T4 GPUs with per-second billing. You select the GPU type per deployment based on your model's memory and throughput requirements.
Z.AI FAQs
What is GLM-5.3?
GLM-5.3 is the latest model in Z.AI's GLM series, supporting a 1M token context window. It is designed for long-document analysis, coding, and enterprise chat applications in both Chinese and English.
Is GLM-5.3 available on Amazon Bedrock?
Yes. GLM-5.3 was added to the Amazon Bedrock catalog in 2026, making it accessible to AWS enterprise customers via the standard Bedrock API without a separate Z.AI account.
How does Z.AI compare to other Chinese LLM providers?
Z.AI's GLM models compete with Alibaba's Qwen and Moonshot's Kimi series. GLM-5.3 stands out for its 1M context window and Amazon Bedrock availability, making it the most accessible Chinese LLM for AWS enterprise customers.

Provider category context
Baseten is a inference api, founded in 2019. Z.AI is a frontier lab, founded in 2019. Baseten as an inference API provider hosts open-weight models — typically offering lower prices for equivalent capability tiers. Z.AI as a frontier lab trains and serves proprietary models with capabilities not available elsewhere.
How to choose between them
Choose Baseten if you need full control over model serving: custom preprocessing, postprocessing, and business logic. Choose Z.AI if you need 1m token context window on glm-5.3. For high-volume production workloads, run a cost comparison using the token pricing table above with your actual prompt/completion token ratio — the cheapest provider depends heavily on your input-to-output token ratio.
