WHY PIONEER
app.py
01 SHIP FAST
From curl to production in 30 seconds.
A single OpenAI and Claude-compatible endpoint. Change one line of code and you’re live.
+ 70+ frontier and open source models including Qwen, DeepSeek, Gemma, Nemotron, and GLiNER
+ Industry-leading tokens per second, sub-200ms p50 latency
+ 99.99% uptime SLA, production-grade from day one
+ Streaming, tool calls, and structured outputs included
View quickstart ↗
02 SEE CLEARLY
Know exactly where your model fails.
Every response is automatically clustered by task and failure mode. See what’s breaking and why across every model you deploy.
+ Auto-clustered failure modes and task breakdowns across every request
+ Supported on all 40+ models on Pioneer
+ Drill into any cluster to see example inputs, outputs, and failure patterns
+ Use failure clusters to drive automatic model improvement

03 GET SMARTER
Your model retrains itself while you sleep.
Your endpoint gets smarter on its own. Adaptive Inference mines failures for high-signal examples and surfaces an improved model behind the same URL.
+ Continuous retraining on live production traffic
+ Download your weights and training datasets at any time
+ Every auto agent run generates a full PDF report
+ Bring your own evals or use ours
