OpenTier turns organizational knowledge into real-time, actionable intelligence. It's secure by design, fast by default, and built to scale with your business.
SYSTEM OUTPUT · SIMULATION MODE
OpenTier combines the performance of Rust with the intelligence of Python,
creating a production-ready platform that scales with your needs.
Handles public API traffic, authentication, tiered rate limits, and SSE streaming with zero-cost abstractions and sub-millisecond overhead.
Strongly-typed Protobuf RPCs connect services while Redis 8 Streams coordinates decoupled events with zero loss guarantees.
Orchestrates multi-provider LLM inference, conversation history, query expansion, and hybrid retrieval isolated from public traffic.
System of record for vector embeddings, executing sub-millisecond dense cosine search fused with sparse BM25 lexical tokens.
Dedicated stream consumers handle heavy background tasks: web scraping, token chunking, embedding generation, and billing metering.
PostgreSQL 18 stores users, organizations, permissions, document metadata, and immutable credit transaction ledgers.
Blazing-fast API gateway built with Axum for maximum throughput, memory safety, and native SSE streaming.
Dense neural embeddings (up to 3072d) fused with sparse BM25 lexical tokens via Reciprocal Rank Fusion.
Redis 8 AOF event streaming with consumer groups, distributed locks, SHA-256 deduplication, and DLQs.
Decoupled background workers executing long-running web scraping, document chunking, and billing metering.
OAuth 2.0, AES-256 encrypted provider keys at rest, session management, and granular RBAC built-in.
Seamlessly route across Google Gemini, OpenAI GPT, and local Ollama models with custom endpoint overrides.
Server-sent events and gRPC server streaming for instant, responsive token-by-token chat experiences.
Docker Compose orchestration, self-healing workers, built-in observability, and zero-downtime migrations.
Download the production compose file, deploy the published GHCR containers, and stream intelligence.
