OpenAI announced GPT-5.5 today, marking a new class of intelligence built to understand complex goals, use tools, check its work, and carry more tasks through to completion. It is now available on Cencori.

You can use it today with:

gpt-5.5

Why This Update Matters

GPT-5.5 is designed for real work and powering agents. By routing your GPT-5.5 traffic through Cencori, you immediately get our security incident logging, custom data rules, routing, and observability applied to this new way of getting computer work done.

No API migration is required. If you already call Cencori chat endpoints, switch the model ID and go.

Use It Now

Cencori SDK

Codetext

import { Cencori } from 'cencori';
 
const cencori = new Cencori({ apiKey: process.env.CENCORI_API_KEY });
 
const response = await cencori.ai.chat({
  model: 'gpt-5.5',
  messages: [
    { role: 'system', content: 'You are an autonomous coding agent.' },
    { role: 'user', content: 'Build a Next.js landing page with authentication.' }
  ]
});
 
console.log(response.content);

HTTP API

Codetext

curl -X POST https://cencori.com/api/ai/chat \
  -H "CENCORI_API_KEY: $CENCORI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.5",
    "messages": [
      {"role": "user", "content": "Analyze these query logs and suggest optimizations."}
    ]
  }'

What We Shipped in Cencori

This rollout is live across the platform:

fallback mapping for cross-provider failover (gpt-5.5 fails over to claude-opus-4.5 and gemini-3-pro)
dashboard model pickers (Playground, Prompts, and Logs)
docs and examples updated

Notes for Production Teams

gpt-5.5 is the API model ID for GPT-5.5.
If you rely on strict model pinning for long-running evals, keep your own pinned fallback policy as usual.
