The author says LongCat 2.5 Preview repeatedly looped while analyzing five C# classes in OpenCode and still had not completed the request after about 20 minutes. This was one personal experience, without complete input or repeated tests.
Tasks this is suitable for assessing: Analyzing relatively complex C# code and suggesting improvements in the OpenCode CLI.
Tasks this should not be extrapolated to: Overall capability with other languages, simple code, or other clients or providers.
Applicable model version: LongCat 2.5 Preview.
Test environment or client: OpenCode CLI. The author says the model was free on OpenCode Go/Zen at the time, but does not specify the server configuration used for this test.
Reasoning tier and parameters: Not specified.
The author asked the model to analyze five C# classes and suggest code improvements, then observed its reasoning process. The author also noted that the code was relatively complex and might not be an ideal model benchmark scenario.
The author reports that the model often looped and repeated the same sentences extensively. The request was still incomplete after about 20 minutes. The post does not provide a completion rate or comparison results from other models on the same task.
| Item | Reported in the post |
|---|---|
| Input size | 5 C# classes |
| Duration | About 20 minutes |
| Result | Request incomplete; reasoning process repetitive |
| Number of tests | Not specified |
This is one user's report of a single task and cannot distinguish the effects of the model, client, or server on the outcome. The post does not disclose the complete code, prompt, parameters, logs, or repeated trials, so the result cannot be independently verified. It also does not show that all LongCat 2.5 use cases would have the same issue.
In the OpenCode CLI, select LongCat 2.5 Preview, ask it to analyze your own C# classes and suggest improvements, and record the full configuration, duration, output, and whether the request completes. Because the original input was not disclosed, this test cannot be strictly reproduced.
