System Update

Released: 2026-03-23

We now support an `apertis/` namespace prefix for all model IDs, designed specifically for **Cursor IDE** users who experience model ID collisions with Cursor's built-in model routing. ### How It Works When your model ID overlaps with Cursor's built-in models, simply add the `apertis/` prefix to ensure requests route through Apertis: | Standard ID | Cursor IDE ID | |-------------|---------------| | `gpt-5.4` | `apertis/gpt-5.4` | | `claude-sonnet-4.5` | `apertis/claude-sonnet-4.5` | | `code:claude-sonnet-4.5` | `apertis/code:claude-sonnet-4.5` | | `gpt-5.4:web` | `apertis/gpt-5.4:web` | The `apertis/` prefix is automatically stripped on our end — all downstream processing (model validation, channel routing, billing, and logging) uses the original model ID. Fully compatible with existing suffixes like `:web` and `code:` prefix and **all models**. ### Model Detail Page Each model's detail page now includes a **Cursor IDE Model IDs** section listing all available `apertis/`-prefixed identifiers. Click to copy, and hover the infoicon for context. **Happy Building**
