GuitarML offers additional free software.

Epoch Amp

• 4 amp models: from clean to edge of breakup, crunchy to high gain
• mix control for mixing in the input signal with the dirty signal
• Epoch Amp is intended to be used as the foundation of your signal chain to add any number of other effects to
• Impulse Responses
• 3D amp model (by John Stutts)

Chameleon

• Chameleon is a guitar plugin using neural networks to create three distinct sounds from a vintage style amp head
• Chameleon's core sound comes from a neural net inference engine which allows the plugin to disguise itself as a high end tube amplifier
• While SmartAmp and SmartAmpPro are more experimental in nature, Chameleon uses the state-of-the-art RTNeural engine which brings CPU usage down to compete with other commercial plugins

Smartamp

• The SmartAmp is a guitar plugin that uses machine learning to mimic all the nuances of a tube amplifier
• It features a clean and lead channel with EQ and gain controls

Proteus

Proteus is a free, open-source plugin and format for modeling guitar amplifiers and effects pedals. Unlike static impulse responses (IRs), Proteus uses machine learning (AI)—specifically, LSTM neural networks—to accurately replicate the nonlinear behavior and dynamic response of tube amps and distortion pedals.  The format saves these models as .json files. For a long time, what set Proteus apart from other AI models was its high efficiency: it offers excellent sound quality with significantly lower CPU usage, making it particularly attractive for live applications or complex sessions.

Key Features:

• Platform: There is a central library, the GuitarML Tone Library, which serves as an exchange platform for .json models. 
• Creation: Users can create (profile) their own models using the “Proteus Capture Utility.”
