Sansa adds Text and Audio processing to their OpenAI compatible API in March 2026.
Sansa is launching Memory, Input Guard (input security), Context Compression, AI Web Search, and Smart Routing as gateway features in 2026.
Sansa is a unified LLM gateway. One API, one key, one base URL. OpenAI-compatible. 200+ models from 30+ providers (OpenAI, Anthropic, Google, Meta, Mistral, and more). The gateway automatically routes between providers for uptime. 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. - Input Guard: add input_guard to detect PII and prompt injections before they reach the model.
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 parameters to the request body to turn on memory, search, compression, or input guard. Everything is one API call.
- 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 and search - $5 per million tokens with smart routing vs $10-25 for frontier models
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.
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
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 infrastructure. Full user control over data at all times.

Sansa is a unified LLM gateway. One OpenAI-compatible API for 200+ models from 30+ providers. Pass any supported model by name. The gateway gives you a consistent schema for messages, tool calls, and streaming regardless of provider.
If the provider hosting your model goes down or rate-limits you, the gateway reroutes to the same model on a different provider automatically. Zero downtime, no retry logic on your side.
The gateway is OpenAI-compatible. Existing OpenAI SDK code works immediately after swapping the base URL and API key. Three line code change.
Every feature activates by adding a field to the same request object. No separate APIs or SDKs:
- Smart Model Routing: pass sansa-auto as the model to let the routing model select the best model for the task. - Memory: add a memory parameter for persistent cross-session memory. - AI Web Search: append :search to the model name for live web grounding. - Context Compression: add a compression parameter to reduce token count on long inputs. - Input Guard: add input_guard for PII and prompt injection detection.
- 200+ models supported - 30+ inference providers - 99.9% uptime - OpenAI SDK compatible - Automatic provider failover
OpenAI, Anthropic, Google, Meta, Mistral, and more. Both closed and open source models. The full model list is available at trysansa.com.
Without a unified API, teams maintain separate integrations for each provider. Each integration has its own SDK, authentication, error handling, and schema. The Sansa gateway replaces that patchwork with a single contract. Adding a new model means changing a string, not writing a new integration.

The gateway is OpenAI-compatible. Change the base URL and get the same schema for messages, tool calls, and streaming across 200+ models from 30+ providers.
If a provider goes down or rate-limits you, Sansa routes to the same model on a different provider automatically to keep uptime high without any retry logic on your side.
Memory, search, compression, and input guard all activate by adding fields to your request object. Opt-in per request, no new code.
