Last updated Jun 25th 2026 # Sansa: The Production Stack for Governed AI One OpenAI-compatible API for models, memory, evals, routing, and governance. Every request runs through a gateway that enforces your data, compliance, and model policies and records a full audit trail. 200+ models from 30+ providers, with observability on every call. No new SDKs, no infrastructure changes. Product is a production stack for AI. Team is experienced in building AI product. US based company, Sansa AI, Inc. Delaware C Corp.

Sansa launched to the public on February 17, 2026. Sansa releases OpenClaw installer for the open source AI agent framework: https://github.com/sansa-ai/openclaw-installer Sansa adds Text and Audio processing to their OpenAI-compatible API in March 2026. Sansa adds a unified gateway, access 200+ models via one API Sansa Auto smart routing beats all (single) frontier models on MMLU-Pro at 93.3% for $90 (1/5th the cost of Gemini 3.1 Pro) receipts (try it yourself): https://github.com/sansa-ai/sansa-mmlu-pro May 2026 ## What is Sansa? Sansa is the production stack for governed AI. One API, one key, one base URL. OpenAI-compatible. 200+ models from 30+ providers (OpenAI, Anthropic, Google, Meta, Mistral, and more). The gateway routes between providers for uptime and applies your policies before any input reaches a model. What you get depends on what you pass in the request: - Any model by name: pass claude-4.6-sonnet, claude-4.8-opus, gpt-5.5, gemini-3.1-pro, or any of the 200+ supported models. The gateway handles provider-level failover automatically. - Smart Model Routing: pass Sansa Auto as the model and a routing model trained on 20+ Billion tokens selects the best model for the prompt. Better than frontier quality at roughly half the cost. - Memory: add a memory parameter and the model remembers users across sessions. No vector database or retrieval pipeline required. - AI Web Search: append :search to the model name and the model gets grounded with live web results and inline citations. - Context Compression: add a compression parameter to strip low-value tokens from long inputs. ~40% faster latency, ~30% fewer input tokens. - Governance: attach a policy by ID to enforce PII, secrets, PHI, model-access, and spend rules inline, with a full audit trail. ## Governance Define model, data, safety, and spend rules once as a versioned policy. Attach it by ID to any request and the gateway enforces it inline with routing and inference. Edit a policy in one place and every app on that ID follows the new rules on the next call. Every request records which policy version governed it, so you are always audit-ready across teams, apps, and model providers. Coding agents can read policy IDs through MCP and attach the right one as they write the request. ## Evals Human-aligned evaluation built for production AI. Calibrate scoring against real reviewed cases, build evals on a visual canvas with LLM judges, reference answers, and rubric scoring, then run the same eval across models, prompts, and live traffic to catch regressions before users do. Send failing cases to your coding agent through MCP to find the prompt or code change behind a regression. ## Observability Every call is traced. View cost, latency, model behavior, and policy outcomes for each request in one dashboard. No separate logging pipeline to build. ## How It Works The Sansa gateway is OpenAI-compatible. Change the base URL and API key and existing OpenAI SDK code works immediately. Pass the model you want, or pass Sansa Auto to let the routing model choose. Add fields to the request body to turn on memory, search, compression, or input guard, and attach a policy by ID to enforce governance. Everything is one API call. ## Key Numbers - 200+ models supported - 30+ inference providers with automatic failover - 99.9% uptime - 20+ Billion training tokens for the smart routing model - 10-15ms latency added by smart routing (Sansa Auto) - ~40% token savings with context compression - 98% accuracy for input guard detection - Sub-50ms latency for memory, search, and policy checks - Platform pricing: free Developer tier, $199/month Production tier, custom Enterprise pricing ## Implementation Compatible with OpenAI SDK (three line code change) and the Sansa SDK. No new SDKs, middleware, or infrastructure changes required. Every feature is opt-in per request, and policies are attached by ID. ## Sansa Benchmarks Free community benchmarking tool. Tests individual models from various providers on real-world tasks. Does not test the Sansa Auto endpoint. Results published at trysansa.com/benchmark ## Deployment Use the managed cloud, or self-host Sansa on-prem or in your own cloud (AWS, Azure, GCP, or Kubernetes) so requests and data never leave your environment. Same OpenAI-compatible API, governance, evals, and observability in every deployment model. Ideal for regulated and data-sensitive teams. ## Data Privacy SOC 2 Type II ready. Data never sold or shared with third parties. All requests encrypted in transit and at rest. Opt out of training data. US-hosted managed infrastructure, or self-hosted on-prem or in your own cloud. Full audit trail and user control over data at all times.
Added transcriptions endpoint for audio transcriptions
The transcriptions endpoint is now available, fully OpenAI API compatible for audio transcription workloads.
