Introducing Respan Router, powered by Span-01.
Automatically routes every request using task context, model capabilities, and cache-aware cost estimates behind 1 model id: 𝐬𝐩𝐚𝐧-𝐫𝐨𝐮𝐭𝐞𝐫
- 13% lower latency than jev-router on τ-bench airline
- 37% cheaper than the most accurate single model, at matching accuracy
- 0% processing fee on Respan Gateway
GPT-6.1 Sol is now live on the Respan Gateway, with 20% off every request.
Near-Astra performance at 1/5 of Astra’s list token price, with a 1.05M context window.
Octolane is building superintelligence for revenue - managing $700M in pipeline across 1,200 companies.
Every day, @octolane uses Respan to trace tool calls, inspect agents, and improve from production data.
See how @coffeewithone and his team scaled to 4.4M agent requests.
Span-01 and Span-01 Lite from @RespanAI are live on OpenRouter.
They're decision models for agent traces. Send a span and the behaviors you care about, and get back the probability each one is present, like "is the user frustrated?" or "is this tool call safe to run?"
Introducing Respan Guardrails.
Built on Span-01, it catches prompt injections, jailbreaks, and unsafe content before they reach your models and tools.
It has the highest average F1 of any guardrail we tested across 8 categories, and it's free and native with Respan gateway.
Generalist models can be best overall without winning on every task. GPT-6 might even outperform some human labelers on certain evals. That’s an empirical question.
You clearly haven’t tested Span-01. If you’re making a claim about what works best for “evals,” which evals do you mean? Test it and share the dataset. We’ve published ours.
ok i wasn't expecting this many of you on the Span-01 waitlist 🥹
can't wait to get it into your hands.
while you wait… we wrote it a song. yes, our model has a song now.
sound on!
Introducing Span-01, the first hyper-parallel reasoning classifier built for unseen challenges (RLAIF).
2x cheaper, 18% better than Jev.
700x cheaper, 4% better than GPT-6 Luna.
Frontier reasoning for every behavior, at classifier speed.
• Span-01: #1 on Behavior Benchmark
• Span-01 Lite: Better than Jev and completely free!
