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.

What is Sansa?

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.

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 parameters to the request body to turn on memory, search, compression, or input guard. 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 and search - $5 per million tokens with smart routing vs $10-25 for frontier models

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.

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

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 infrastructure. Full user control over data at all times.

What It Does

Append the :search suffix to any model name in your request and the gateway fetches relevant web pages before generation. No separate search API to wire, no tool-call orchestration on your side.

Pages are stripped of boilerplate and distilled into information-rich snippets. Model answers include inline citations and source links. Your agent reasons over facts instead of noise.

How It Works

1. You add :search to the model name in your request (e.g., "gpt-4o:search"). 2. The gateway queries the web for content relevant to the prompt. 3. Retrieved pages are cleaned, compressed, and injected into the model context. 4. The model generates an answer grounded in live web data, with inline citations.

Works on Every Model

Search works on any model through the Sansa gateway, including models that do not support web search natively. Over 200 models supported.

Key Numbers

- Sub-50ms search latency - 10 Billion+ web pages indexed - 99.9% uptime - Inline citations and source links in every response - Works with any of the 200+ models on the gateway

Why It Matters

LLMs have knowledge cutoff dates. For questions about current events, live data, or rapidly changing topics, web search provides the model with up-to-date information at generation time. Adding search to any model eliminates the need to build and maintain a separate retrieval pipeline for public web data.

Integration

One suffix on the model name. The gateway is OpenAI-compatible. Change the base URL and API key and existing OpenAI SDK code works. Search activates per request.

Part of the Sansa Gateway

AI Web Search is one feature of the Sansa gateway. Other features include smart model routing (sansa-auto), persistent memory, context compression, input guard, and automatic provider failover. All activate through the same API by adding parameters to the request.
