# 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. Reach

## 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-3.5-sonnet, gpt-4o,
gemini-2.5-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.

# Sansa Full Stack AI API

One OpenAI-compatible API for models, memory, evals, routing, and
governance. 200+ models from 30+ providers behind a single contract.
Swap the base URL and your existing OpenAI SDK code keeps working,
with observability and policy enforcement on every call. No new SDKs,
no infrastructure changes.

## Drop-in Compatibility

The gateway is OpenAI-compatible. Existing OpenAI SDK code works
immediately after swapping the base URL and API key. Messages, tool
calls, and streaming stay the same across every provider. Three line
code change.

## 200+ Models and Smart Routing

Pass any supported model by name and the gateway handles
provider-level failover automatically, or pass Sansa Auto and a
routing model trained on 20+ Billion tokens selects the best model
for each prompt at roughly half the cost of frontier models.

## Memory for Any Model

Attach a user or agent ID and the gateway recalls relevant context
before each call and updates memory after the response. No vector
database or retrieval pipeline required.

## Observability on Every Call

Every request is traced. View cost, latency, model behavior, and
policy outcomes for each call in one dashboard. No separate logging
pipeline to build.

## Governance and Guardrails

Add input_guard to detect PII and prompt injections before they reach
the model, or attach a policy by ID to enforce data, model, safety,
and spend rules inline with routing and inference. Every request
records a full audit trail.

## Why It Matters

Teams need real infrastructure to build performant AI: model access,
memory, evals, and routing. They also have to stay compliant and
operate in regulated spaces. Most stacks force a choice between moving
fast and staying governed. Sansa gives you both in one
OpenAI-compatible request path, where every capability runs with
compliance, security, and a full audit trail built in by default.
