Products, side by side
Hand-checked pairing
Modal
Developer tool
Hosted notebooks backed by Modal's GPUs, for profiling and experimenting without provisioning a machine.
Infrastructure service
Serverless GPU compute: a Python decorator puts a function on an accelerator, scales it from zero to thousands of containers and stops billing when it stops running — aimed at inference, fine-tuning and batch jobs rather than reserved clusters.
Batch execution of large jobs across Modal's fleet, described as one line of code on the product page.
Serve, scale and optimise model inference on Modal's runtime, with sub-second cold starts and autoscaling across regions.
Isolated, instantly-started containers for running untrusted or agent-generated code at scale — the primitive behind AI app-generation products.
Managed training runs on Modal's fleet, configured in Python alongside the rest of a team's code.
Together AI
Developer tool
Custom model training service covering supervised fine-tuning and direct preference optimization, billed per token.
Infrastructure service
Dedicated, reserved GPU containers for model inference with guaranteed performance, billed per GPU-hour.
Reserved NVIDIA GPU clusters for training and large-scale inference.
No counterpart
Together AI sells these in a stack layer with no product recorded for Modal yet — nothing on the other side to compare them against.
API service
Asynchronous bulk inference for workloads that do not need a real-time response, priced below Together's serverless rate.
A managed service for fine-tuning open-source models on a customer's own data and serving the result on Together's infrastructure.
Model API
Hosted API serving open-weight text, image and audio models, billed per token.
