Mixpeek for AI/ML Engineers

Build multimodal AI applications on production-ready embedding and retrieval infrastructure

AI and ML engineers building multimodal applications need reliable embedding generation, vector indexing, and retrieval infrastructure that scales beyond notebook experiments. Mixpeek provides the serving layer for your models -- handling ingestion, feature extraction, embedding storage, and composable retrieval -- so you can focus on model architecture and evaluation rather than infrastructure plumbing.

What's Broken Today

1Prototype-to-production gap

Models that work in notebooks fail in production due to missing infrastructure for batching, error handling, scaling, and monitoring. Bridging this gap requires significant engineering effort unrelated to model quality.

2Multi-model orchestration complexity

Production multimodal systems often chain multiple models -- embedding, classification, detection, transcription -- requiring careful orchestration of dependencies, versioning, and fallback behavior.

3Embedding infrastructure overhead

Running, scaling, and maintaining embedding model endpoints with GPU provisioning, batching optimization, and health monitoring consumes engineering time that should be spent on model research.

4Evaluation and iteration friction

Comparing retrieval quality across model versions, embedding dimensions, and indexing strategies requires reproducible evaluation pipelines that most teams build ad-hoc.

How Mixpeek Helps

Managed model serving at scale

Deploy embedding and classification models through Mixpeek's distributed Ray-based inference infrastructure with automatic scaling, batching, and health monitoring built in.

Custom extractor system for your models

Register custom feature extractors that call your own model endpoints. Plug proprietary or fine-tuned models into the pipeline while leveraging Mixpeek's orchestration, retry logic, and monitoring.

Composable retrieval for evaluation

Build retrieval pipelines with filter, search, and rerank stages. Compare different configurations side by side to evaluate retrieval quality across model versions and embedding strategies.

End-to-end pipeline observability

Monitor embedding throughput, extraction latency, and indexing status through the API. Track model performance metrics across the entire pipeline from ingestion to retrieval.

How It Works for AI/ML Engineers

Register custom models as feature extractors

Package your embedding, classification, or detection models as Mixpeek extractors. Define input/output schemas and configure GPU requirements, batching parameters, and health checks.

Configure extraction pipelines per experiment

Create collections with different extractor configurations to test model variants. Each collection defines which models run, in what order, and how outputs are stored.

Ingest evaluation datasets

Upload evaluation datasets to S3 buckets and trigger batch processing. Mixpeek handles distributed extraction across GPU workers with progress tracking and error reporting.

Build retrieval pipelines for evaluation

Define retriever configurations with different search strategies, reranking models, and scoring weights. Run evaluation queries against each configuration to compare retrieval metrics.

Iterate on model and pipeline configuration

Swap models, adjust embedding dimensions, change chunking strategies, and re-run evaluations. Mixpeek handles reprocessing and re-indexing while you focus on architecture decisions.

Promote winning configuration to production

Once evaluation confirms the best model and retrieval configuration, promote it to production namespaces. Monitor throughput and quality metrics through the observability API.

Frequently Asked Questions

Can I use my own fine-tuned embedding models with Mixpeek?

Yes. Mixpeek's extractor system lets you register custom feature extractors that call any model endpoint. You define the input/output schema, and Mixpeek handles orchestration, batching, retries, and monitoring. This works with HuggingFace models, custom PyTorch endpoints, or any HTTP-based inference service.

How does Mixpeek handle GPU provisioning for model inference?

Mixpeek uses Ray for distributed model serving across GPU and CPU workers. The infrastructure handles auto-scaling, request batching, and load balancing. You configure resource requirements per extractor, and the system allocates compute accordingly. For self-hosted deployments, you control the GPU cluster configuration directly.

Can I compare retrieval quality across different embedding models?

Yes. Create separate collections with different extractor configurations, process the same dataset through each, and build retriever pipelines against each namespace. Run evaluation queries and compare precision, recall, and latency metrics side by side. This is the recommended workflow for model selection and hyperparameter tuning.

What embedding dimensions and vector types does Mixpeek support?

Mixpeek supports arbitrary embedding dimensions and stores vectors in the Mixpeek Vector Store, which handles dense, sparse, and multi-vector representations. There are no hard limits on dimensions -- the system adapts to whatever your models produce. Named vectors allow storing multiple embedding types per document.

How do I handle model versioning when upgrading embeddings?

Create a new collection configuration with the updated model, trigger batch reprocessing of existing data, and index the new embeddings into a separate namespace. Once validation confirms the new embeddings perform better, switch production retrievers to the new namespace. The old namespace remains available for rollback.

Does Mixpeek support multi-stage retrieval with reranking?

Yes. Retriever pipelines support composable stages: initial candidate retrieval via vector search, filtering by metadata, and reranking with cross-encoder or other scoring models. Each stage is independently configurable, and you can chain them in any order to build complex retrieval strategies.

What monitoring and observability does Mixpeek provide for ML pipelines?

The API exposes batch processing status, per-object extraction results, throughput metrics, and error details. You can track embedding generation latency, extraction success rates, and indexing progress. For self-hosted deployments, the admin dashboard provides real-time engine performance metrics including VRAM usage and worker utilization.

Can I use Mixpeek for model evaluation without deploying to production?

Yes. Create isolated namespaces and collections for evaluation purposes. Process evaluation datasets, run retrieval benchmarks, and compare results without affecting production data or configurations. This is the recommended workflow for model experimentation and A/B testing before promotion.
