Last updated: 2026-09-17 — GPT-6 Astra shipped on September 3, 2026. This setup guide was written before launch; every config now uses the confirmed model ID
gpt-6-astra, and the coding-benchmark FAQ reflects the published scores. Specs and background: What Is GPT-6 Astra.
Quick Answer
GPT-6 Astra shipped on September 3, 2026, and using it in Codex, Cursor, or Claude Code is the same OpenAI-compatible setup as GPT-5.6: point base_url at an OpenAI-compatible gateway, add your key, set the model name to gpt-6-astra. These tools don't need to know anything about "Astra" — they only speak the OpenAI-compatible contract and pass the model ID through. With TeamoRouter, one key switches between GPT-6, Claude, and DeepSeek.
No card at all? You can also top up with USDT, USDC or ETH: click Pay with crypto in the top-up dialog and send it from Binance, OKX or any wallet. The minimum is $5 and no browser extension is needed. Step by step: Pay for Claude and GPT APIs with crypto (USDT).
Why It Works Everywhere
Codex, Cursor, Claude Code, and Cline all abstract the "model provider" as an OpenAI-compatible endpoint. Give them a base_url that responds plus a valid model name, and they work. So "connecting Astra" = "provide an OpenAI-compatible entry + tell it the model name."
Cursor
Cursor → Settings → Models → enable OpenAI API Key, then fill in:
Base URL: https://api.teamorouter.ai/v1
API Key: sk-teamo-xxxxxx
Enter gpt-6-astra in the model list — that is the official API model ID. The same config also runs GPT-5.6 Sol if you switch the model name. For GPT-6 Sol's model ID and Codex CLI config, see GPT-6 Sol API pricing, model ID and Codex CLI setup.
Claude Code
Switch the provider via environment variables:
export ANTHROPIC_BASE_URL="https://api.teamorouter.ai"
export ANTHROPIC_AUTH_TOKEN="sk-teamo-xxxxxx"
Or specify the model directly with claude --model gpt-6-astra. Claude Code's provider abstraction is OpenAI-compatible too — change base_url + model and you're done. If you're also routing Claude's own flagship through the same key, the Claude Fable 5.1 API guide covers that side.
Codex
# ~/.codex/config.toml
model = "gpt-6-astra" # the official API model ID
model_provider = "openai"
Or env vars:
export OPENAI_BASE_URL="https://api.teamorouter.ai/v1"
export OPENAI_API_KEY="sk-teamo-xxxxxx"
Route by Task, Don't Lock One Model
Once connected, the pragmatic pattern is task-based routing, not "Astra everywhere":
| Task | Model |
|---|---|
| Complex refactor, hard bug, architecture | GPT-6 Astra / Claude |
| Daily completion, simple Q&A | GPT-5.6 Terra / DeepSeek |
| Batch generation, low-value | GPT-5.6 Luna / DeepSeek V4 Flash |
One gateway key makes this a model string change across tools — no per-provider accounts, top-ups, or configs. Astra on simple tasks is just wasted money (the GPT-6 Astra pricing breakdown shows why). For batch and simple tasks, GPT-6 Luna's model ID and setup are in GPT-6 Luna API pricing and setup. The gateway balance can be topped up by card or with USDT, USDC or ETH from any exchange app (how).
If you're new to calling Astra itself, start with How to use GPT-6 Astra, then come back to the per-tool configs above.
FAQ
Q: Do these tools need a version upgrade for Astra? Usually not — they speak the generic OpenAI-compatible protocol. Some may require manually entering a "custom model name" in the list.
Q: Will Claude Code treat an OpenAI-model as Claude? No. You're explicitly setting the provider via base_url, and the model name is passed through as you configure it.
Q: Is Astra actually better at coding? On OpenAI's own table, slightly: 74.1% on DeepSWE v1.1 versus 72.7% for GPT-5.6 Sol — vendor-reported and within run-to-run noise on real codebases. Independent coding results against Claude Fable 5.1 are mixed (see GPT-6 Astra benchmarks). Test it on your own repo before making it the daily driver.
Summary
Codex / Cursor / Claude Code connect to GPT-6 Astra with three fields: Base URL, API Key, Model ID. Astra shipped on September 3, 2026, so one multi-model key and the model ID gpt-6-astra are all you need today. Sign up for TeamoRouter and flip between GPT-6, Claude, and DeepSeek in every tool.
