Aion 3.5
A text-generation model listed in the provider catalog. We have not verified its general-task or storytelling performance in comparable independent tests.
Released 2026-09-23 · Catalog added 2026-09-23 UTC · Checked 2026-10-11. Catalog addition and provider launch are separate dates.
We still need comparable independent tests. You can compare the confirmed prices and limits below, but we cannot yet give this version an Agent Fit or Practical Value rating, or recommend a thinking setting. Try it on your own tasks before switching. Results for an older or differently configured version may not apply.
What you can use today
Token prices measure the small pieces of text the model reads or produces. Capacity, often called the context window, is the amount it can handle in a request. A dash means we could not confirm the price.
Exact catalog ID: aion-labs/aion-3.5. AionLabs describes a GLM-family system that uses several cooperating models. It is a composite system; individual constituent scores are not assigned to this endpoint. Native documentation verifies the September 23 release and 256K input context with up to 32K output. The selected routed offer retains its separately observed limits and price. Test accuracy, speed and reliability on your own tasks.
Rates describe the catalog offer observed on 2026-10-11. Your bill can also depend on discounts for reused input, which provider handles the request, speed options, tools, retries and charged thinking tokens.

Test it before switching
Give each model the same examples, tools and definition of success. Record correct outcomes, response time, retries, token use and total cost. Even at the same price per token, a different version can cost more if it uses more tokens.
