**APIs profiled:** 0

An index and topic collection covering machine learning APIs, MLOps platforms, model serving infrastructure, and inference providers. Machine learning APIs span the full ML lifecycle — from data labeling, experiment tracking, and model training to model registries, hosted inference, and vector search. This collection brings together hyperscaler ML platforms (Amazon SageMaker, Google Vertex AI, Azure Machine Learning), open-source MLOps frameworks (MLflow, Kubeflow, ZenML, DVC), GPU inference providers (Together AI, Fireworks AI, Replicate, Groq, Modal, Baseten), vector databases (Pinecone, Weaviate, Milvus, Qdrant, Chroma), and model hubs (Hugging Face) that together power production machine learning at scale.

## Use cases (8)

- **Retrieval-Augmented Generation** — Combining a vector database (Pinecone, Weaviate, Qdrant) with an embeddings API and an LLM inference endpoint to ground model responses in private knowledge bases.
- **Fine-Tuning Foundation Models** — Using SageMaker, Vertex AI, OpenPipe, or Together AI APIs to fine-tune open foundation models on proprietary datasets and deploy the resulting model behind a managed inference e...
- **Scalable Model Inference at the Edge** — Deploying optimized models through Groq, Modal, Replicate, or Baseten to serve high-throughput, low-latency inference for chatbots, recommendation systems, and content generation.
- **End-to-End MLOps Automation** — Using Kubeflow, MLflow, Weights & Biases, and ZenML to track experiments, register approved models, trigger retraining, and promote models to production via API.
- **Multimodal Application Development** — Composing image, audio, video, and text models from Hugging Face, Replicate, and Fireworks AI through standard inference APIs to build multimodal user experiences.
- **Semantic Search and Recommendations** — Indexing product catalogs, documents, or media in vector databases like Milvus or Vespa and exposing semantic search APIs to power discovery and personalization.
- **Model Observability and Cost Control** — Using gateways like Portkey and LiteLLM alongside observability platforms to monitor inference latency, cost-per-request, and routing decisions across multiple model providers.
- **Distributed Training at Scale** — Running large-scale distributed training jobs on Ray, Anyscale, Determined AI, or Databricks via API, including hyperparameter tuning and GPU cluster orchestration.
