OpenRouter adds free Ling 3.2 Flash access for up to 200 images per request

OpenRouter added Ant Group’s Ling 3.2 Flash to its free model catalog on November 13. The model gateway lists a price of zero for both input and output tokens. Its public endpoint data checked on November 15 shows Ant Digital serving the route.

The addition gives developers who already use OpenRouter’s chat API a way to send text and images together and get a text response. The listing allows up to 200 images per request and specifies a context window of 1,048,576 tokens. OpenRouter applies its free-model request limits to the route.

What the free endpoint accepts

Ant Group’s Ant Ling team introduced Ling 3.2 Flash on its own platform on November 5. The developer documents a model with 560 billion parameters in total and about 25 billion active per token. Ant Ling lists video alongside text and images for the model it introduced. OpenRouter’s free route lists two input types, text and images, and returns text.

The gateway uses its existing image-input format. A request can carry a written question and an image in the same message. OpenRouter’s guide describes two ways to supply the image. A hosted picture can be referenced by URL, while the contents of a file can be encoded and sent with the message. A screenshot with instructions about which part of the screen to inspect is one example. Because the input format is shared, a developer comparing two image-capable models can keep the message the same and change the model identifier.

The image count and context window are separate limits. OpenRouter explains that image resolution can affect how many tokens a picture uses. Two requests with the same number of images can therefore consume different amounts of context. The endpoint data lists a separate maximum of 262,144 output tokens for a completion.

The route also lists structured outputs and function calling. Those options let a developer ask for information in fields an application can read or have the model request an external function. A result might, for example, put the fields visible in a screenshot into a specified data format for a subsequent step. The model listing also gives callers the option to switch reasoning off for a request.

Request limits and European routing

OpenRouter caps its free variants at 20 requests per minute and normally 50 per day. The daily allowance can increase to 1,000 for accounts with qualifying credit purchases. The allowance applies at the account level across free variants. The company counts unsuccessful attempts toward the daily cap. A workflow that retries failed calls can therefore use up more requests than the number of answers it receives.

The public endpoint data lists one provider for this model on OpenRouter. Applications that use the gateway to switch between providers have only Ant Digital available for this free route. OpenRouter tracks whether a provider could be reached separately from whether it delivered a response. Errors and empty responses reduce its published availability figure.

Ant Ling’s November 5 update advertised an introductory two-week free period on its own platform. OpenRouter created a separate listing on November 13. Each route has its own terms and accepted inputs. The OpenRouter listing gives no end date for its free offering.

OpenRouter marks this route as unavailable through its European in-region service. Its regional addresses send requests only to endpoints enrolled for the chosen region. With no eligible endpoint for this model in Europe at the time of reporting, requests to the regional address would return an error without falling back to another region.
