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.

Context Compression is a feature of the Sansa AI gateway. It strips low-value tokens from long inputs to reduce cost, improve latency, and preserve (or improve) output quality.
Long inputs mix signal with boilerplate and noise. A compression model scores every span of text for relevance, then removes low-importance content before the LLM sees it. You control the compression level: low for precision tasks, heavy for maximum savings.
This is semantic scoring, not truncation. The model understands what matters in context and keeps it.
- ~40% faster end-to-end latency - ~30% fewer input tokens - Compression overhead below 20ms - Quality preserved at 99%+ on benchmarks
In benchmarks, context-aware compression improved reading comprehension and output quality. Less noise in, better answers out.
1. Your request passes through the Sansa gateway. 2. The compression model scores each span of input text for relevance to the prompt. 3. Low-importance spans are removed. 4. The compressed input is forwarded to the selected LLM. 5. You receive the model response as normal.
Compression level is configurable per request.
- ~40% latency improvement - ~30% token savings - Sub-20ms compression overhead - 99%+ quality retention - Works with any of the 200+ models on the gateway
Token costs scale with input length. Long conversation threads, documents, and RAG contexts accumulate tokens quickly. Compression reduces spend and latency on every request without requiring you to manually trim context.
Enable compression by adding a parameter to the request body. The gateway is OpenAI-compatible. Change the base URL and API key and existing OpenAI SDK code works. Compression activates per request.
Context Compression is one feature of the Sansa gateway. Other features include smart model routing (sansa-auto), persistent memory, AI web search, input guard, and automatic provider failover. All activate through the same API by adding parameters to the request.

Context compression
Context compression intelligently strips tokens from long inputs, lowering costs, improving latency, and preserving quality.
TOKEN SAVINGS
QUALITY
LATENCY
Long inputs mix signal with boilerplate and noise. In benchmarks, context aware compression improved reading comprehension and output quality. Less noise in, better answers out.
Context compression analyzes all of the tokens within your prompt to evaluate their semantic weight and relative importance. When a large language model works to process the inputs it receives, every word contributes to its overall understanding. But not equally. Many filler words can be completely stripped away while leaving the core meaning intact. To achieve this, a scoring function evaluates each of the input token's significance and assigns a retention probability. Tokens falling below the retention threshold are pruned from the text. The resulting output is denser and preserves the original intent and contextual meaning while using fewer tokens, resulting in lower cost, higher quality responses, and improved long context understanding.
Our compression model scores every span of text for relevance, then strips low-importance text before your LLM sees it. You control the compression level: low for precision tasks, heavy for maximum savings.
~40% faster end-to-end latency. ~30% fewer input tokens. Compression overhead sits below 20 ms. Speed and savings without a quality trade-off.
