Answered from the vendors’ own pages

Inflection AI: Is Inflection AI's Pi service free to use?

The website invites users to 'Try Pi' but does not disclose pricing details, whether there is a free tier, usage limits, or what happens after a trial period.

Source
Keras: What is Keras?

Keras is a high-level deep learning API built on top of TensorFlow that simplifies building and training neural networks. Keras 3 supports multiple backends including TensorFlow, PyTorch, and JAX, making it backend-agnostic.

Source
Inflection AI: Does Pi have a paid tier or premium features?

Pricing information is not published on Inflection's main website. Users must try the Pi platform or contact support to learn about premium options or costs.

Source
Keras: What model architectures does Keras support?

Keras supports the Sequential model for linear stacks of layers, the Functional API for arbitrary graph architectures, and model subclassing for custom implementations. All approaches provide access to layers, optimizers, metrics, and callbacks.

Source
Inflection AI: What commercial terms apply to using Pi?

Inflection does not disclose subscription models, pricing tiers, commercial licenses, or terms of service on their homepage, directing questions to support channels.

Source
Keras: Can Keras models run on TPUs and GPUs?

Yes, Keras models can run on TPU Pods or large GPU clusters, be exported to run in browsers or on mobile devices, and be served via web APIs.

Source
Keras: Does Keras offer pre-trained models?

Yes, Keras provides pre-trained models through KerasHub and Keras Applications for common deep learning tasks like image classification, object detection, and NLP.

Source
Keras: Who should use Keras?

Keras is ideal for beginners and rapid prototyping due to its simplicity and user-friendly interface. Advanced users and production deployments may benefit more from lower-level frameworks like TensorFlow or PyTorch for greater customization.
