Why do Transformer models like BERT use GELU instead of the traditional ReLU activation function? The answer lies in how these functions process information. While ReLU completely removes negative inputs, GELU uses a smooth, input-dependent mechanism to decide how much information should pass through. This small mathematical difference can influence how neural networks learn complex […] The post GELU Activation Function Explained: How It Works and Why Transformers Use It appeared first on Analytics Vidhya.

How OpenSmartRoute helps
For a team that routes through the router, a release like this is one catalogue entry. The new model competes on the next request against what the team already runs, on quality, cost and speed. If it answers well it earns more traffic; if it fails it gets less, with no code change in the app.
Any OpenAI-compatible provider works, as do open-weight models served locally. The catalogue at https://opensmartroute.ai lists models with their prices and live rankings, and the savings ledger shows what the routing saved against always using the most expensive option.
