rubidium inference

we help organizations deploy, customize, and train open-weight large language models for domain-specific workloads where control, privacy, latency, and cost matter.

Model Strategy & Selection

Open-Weight Model Assessment

Evaluation of model families, licenses, context windows, deployment constraints, and benchmark fit for your use case.

Inference Roadmaps

Practical plans for moving from prototype prompts to reliable model-backed workflows, including architecture, data, and operations.

Benchmark Design

Task-specific evaluation sets and scoring methods that make model quality, latency, and cost tradeoffs visible.

Custom Deployment Architecture

Private Cloud & On-Prem Deployments

Deployment of open-weight LLMs in private cloud, VPC, or on-prem environments where control and data residency matter.

Inference Serving & Optimization

Serving stacks, batching, caching, quantization, and GPU sizing to improve throughput, latency, and cost efficiency.

Production Observability

Monitoring for model performance, request patterns, latency, error rates, and infrastructure health in production environments.

Domain Adaptation & Training

Supervised Fine-Tuning

Preparation and training of domain-specific instruction datasets to adapt open-weight models to specialized workflows.

Lightweight Model Customization

Efficient adaptation of open-weight models for targeted tasks without the cost and complexity of full-model retraining.

Training Data Pipelines

Data cleaning, labeling workflows, synthetic data generation, and evaluation splits for reliable model improvement cycles.

Retrieval & Tool Integration

Retrieval-Augmented Generation

RAG systems with document processing, embeddings, retrieval evaluation, and prompt orchestration for grounded responses.

Workflow & API Integration

Integration of models with internal systems, tools, and APIs so inference can support real operational processes.

Agentic Application Design

Design of constrained tool-using model workflows with explicit state, permissions, and handoff points.

Evaluation, Safety & Operations

Quality & Hallucination Testing

Evaluation harnesses that test factuality, refusal behavior, task completion, and regression risk before deployment.

Safety Guardrails

Policy design, red-team testing, output controls, and escalation workflows for sensitive model deployments.

Model Operations Support

Release processes, rollback plans, monitoring routines, and continuous evaluation for production model systems.
