Quick Answer
Using GPT-6 Astra in Codex, Cursor, or Claude Code is the same OpenAI-compatible setup as GPT-5.6 today: point base_url at an OpenAI-compatible gateway, add your key, set the model name to gpt-6. These tools don't recognize the "Astra" codename — they only speak the OpenAI-compatible contract. With TeamoRouter, one key switches between GPT-6, Claude, and DeepSeek.
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.com/v1
API Key: sk-teamo-xxxxxx
Enter gpt-6 in the model list (replace with the official name on launch). Until then, the same config runs GPT-5.6 Sol.
Claude Code
Switch the provider via environment variables:
export ANTHROPIC_BASE_URL="https://api.teamorouter.com/v1"
export ANTHROPIC_AUTH_TOKEN="sk-teamo-xxxxxx"
Or specify the model directly with claude --model gpt-6. Claude Code's provider abstraction is OpenAI-compatible too — change base_url + model and you're done.
Codex
# ~/.codex/config.toml
model = "gpt-6" # replace with the final official name
model_provider = "openai"
Or env vars:
export OPENAI_BASE_URL="https://api.teamorouter.com/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.
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? Indirect evidence only (10 math proofs, multi-agent). No official coding benchmark. 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. Prep one multi-model key now and you're ready the day it ships. Sign up for TeamoRouter and flip between GPT-6, Claude, and DeepSeek in every tool.
