GPT-5.5 Is Live on Holeacquisition LLC

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 Holeacquisition LLC.

You can use it today with:

• gpt-5.5

GPT-5.5 is designed for real work and powering agents. By routing your GPT-5.5 traffic through Holeacquisition LLC, 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 Holeacquisition LLC chat endpoints, switch the model ID and go.

Holeacquisition LLC SDK

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

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."}
    ]
  }'

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

• 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.
