Changelog Entry

Description

Fixed an issue where specific model "stop" tokens (e.g., <|system|>, <|user|>) in model descriptions were not displayed correctly. Previously, these tokens were being inadvertently removed or corrupted by an overzealous sanitization rule, making model descriptions appear incomplete or malformed.

Changed

Updated the sanitizeResponseContent utility function (src/lib/utils/index.ts) to reorder string replacement operations. Specifically, the general HTML entity escaping for < and > characters is now performed after specific regex-based cleanups, ensuring that essential tokens are properly escaped for rendering rather than being removed or altered.

Fixed

Corrected the display of special tokens (e.g., <|system|>, <|user|>, <|end|>, <|assistant|>) within model descriptions in ChatPlaceholder.svelte and Placeholder.svelte, ensuring they are now rendered literally as intended.

Additional Information

The issue was traced to the sanitizeResponseContent function where a replaceAll(/<\|[a-z]+\|>/g, ' ') operation was occurring before the general HTML escaping for < and > characters. By moving this specific replaceAll operation to occur after the HTML escaping, the tokens are now correctly converted to their HTML entity equivalents (<|token|>) and displayed as plain text by the browser, rather than being replaced with a space.
