Aion 3.5 Mini API: frequently asked questions
Aion 3.5 Mini is a multi-model roleplaying and storytelling system from AionLabs, built on the GLM family of models.
Aion 3.5 Mini costs $0.70 per 1M input tokens and $1.40 per 1M output tokens. Cached input costs $0.18 per 1M tokens. These are OceanToken starting prices as of November 5, 2026, charged per use to your prepaid balance. The console always shows the current price.
Aion 3.5 Mini has a context window of 262K tokens (262,144 tokens).
Aion 3.5 Mini supports tool calling and reasoning. It takes text input and returns text. The catalog does not list image input (vision) for it.
Send requests to https://api.oceantoken.ai/v1/chat/completions with the model ID aion-labs/aion-3.5-mini and your OceanToken API key. The API is OpenAI-compatible, so an OpenAI SDK needs only the base URL https://api.oceantoken.ai/v1 and your key. The Responses API and the Anthropic Messages API (/v1/messages) work too. The same OceanToken API key works for every model your account can use. Full reference: docs.oceantoken.ai.
OceanToken is prepaid. Open Credits in the console, choose an amount and pay by card on Stripe's hosted checkout page (Link works too). Your balance updates a few seconds after payment. Have a trial code? Redeem it on the same page.
Purchased credits are valid for 12 months from the date of purchase. Credits from trial codes, promotions or gifts may have a shorter validity. All purchases are final and non-refundable, except where the law requires a refund. Section 6 of the Terms of Service has the details.
Not if the request never ran: a request refused for an insufficient balance or by a safety check, or one whose provider fails before returning any output, is not charged. A video job that fails releases the amount it held. If a request breaks off after the model has started producing output, for example a stream cut off part-way, you pay for the tokens that were processed and generated for it.
