GPT-6 Astra vs Sol: which Codex model should you pick?
For most day-to-day Codex coding, GPT-6.1 Sol is the better default. Save Astra for the hardest jobs where quality matters more than token burn.
Head-to-head
| GPT-6 Astra | GPT-6.1 Sol | |
|---|---|---|
| API id | gpt-6-astra | gpt-6.1-sol |
| Role | Absolute flagship | Near-Astra coding / preferred default |
| API $/1M in/out | $10 / $50 | $2 / $10 |
| Codex burn | Highest | Much lower than Astra |
| When to pick | Hardest end-to-end jobs | Most daily coding agents |
GPT-6 Sol (gpt-6-sol) remains in some Work/Codex pickers at the same $2 / $10 standard API band as GPT-6.1 Sol—check your client’s model list. OpenAI’s GPT-6.1 Sol post positions it as near-Astra intelligence at roughly one-fifth Astra’s standard token prices.
Practical Codex recommendation
- Default new coding sessions to GPT-6.1 Sol.
- Escalate to Astra when Sol stalls on architecture, long ambiguous refactors, or brittle computer-use.
- Use Terra for snappy writing/vision/CU style work; Luna for bulk cheap passes.
- Watch Settings → Usage: Astra’s 5–45 vs Sol’s 15–160 style estimates (Plus/Standard) show why Sol lasts longer.
About “Astra vs Fable 5.1”
Claude Fable 5.1 appears in OpenAI’s own public evaluation tables (for example Terminal-Bench 4.0 comparisons in Astra / work announcements). It is a competing frontier model family from Anthropic’s naming in those posts—not an OpenAI Codex model. We do not invent cross-vendor pricing; compare vendor docs if you evaluate outside OpenAI.

Call via API / relay
Besides ChatGPT-signed Codex plan allowance, you can call gpt-6-astra, gpt-6.1-sol, gpt-6-luna, and related models with an OpenAI-compatible API key (pay-as-you-go). If you need a third-party API relay for access or billing convenience, try TryAllAPI (tryallapi.com / APIPRO).
