Tasks and inputs
LongCat-2.0 is listed for Text generation. It accepts text and produces text. Use the publisher’s input format and preprocessing for your chosen deployment.
LongCat-2.0 from Meituan: Meituan LongCat-2.0, a reasoning model with tool calling and a 1M-token context window.
The specification score summarizes recorded features and limits. It is not a benchmark result.
Recorded modality support shows what this model can accept and produce. An undocumented modality is shown as unknown rather than assumed to be unsupported.

Meituan LongCat-2.0, a reasoning model with tool calling and a 1M-token context window. The registry places it in the longcat family with a release date of 2026-06-30. This profile describes its documented interface and how to evaluate it for the intended task.
The recorded inputs are text, with text output. The registry lists a 1,000,000-token context window and up to 131,072 output tokens. It also declares reasoning and function calling. These are specifications, not a measured quality or speed ranking. A host can impose its own request limits and support a different subset of features.
LongCat-2.0 is recorded as a hosted model without downloadable weights. Confirm the current model ID and access conditions on the chosen API. A registry listing alone does not establish that an account or region has access.
No independently checked token rate is added from a hosting alias. Use the route’s current price and billing unit when comparing cost, including output, reasoning, cache behavior and retries where applicable.
Use tasks with checkable intermediate steps and a clear final answer. Keep reasoning settings and tool access consistent across candidates. Count the tokens and retries needed for an accepted result; a context limit or reasoning flag does not predict task accuracy.
This is a registry-sourced profile. A model-specific publisher document has not yet been confirmed; access and specifications should be checked before an integration decision. SyncDev has not independently benchmarked LongCat-2.0.

LongCat-2.0 is listed for Text generation. It accepts text and produces text. Use the publisher’s input format and preprocessing for your chosen deployment.
Documented limits: 1M context and 131.07K maximum output. The listed route charges $0.75 input and $3.00 output per million tokens. Measure a completed task using the prompts, documents and tools your application will use. Include reasoning and retries in the result.
Use the model identifier and account requirements for the selected API route. Confirm its request limits and output format with one complete task before connecting a larger workflow.
These records share a directory category. Check the source card, output type and deployment requirements before treating a model as a replacement.
