Together AI - Open-Source Model API & Fine-Tuning Platform

Together AI offre API e infrastrutture per l’esecuzione, il fine-tuning e l’addestramento di modelli di IA aperti.

In inglese

Together AI is a developer platform for serverless and dedicated model inference, batch processing, fine-tuning, GPU clusters, sandboxes, and managed storage. It supports text, image, audio, video, transcription, embeddings, reranking, and moderation workloads.

Developers and AI teams use it to build applications, agents, media features, and production model deployments. Pricing is usage-based rather than subscription-based; dedicated infrastructure, compute, storage, and fine-tuning cost extra, and the platform requires at least $5 in purchased credits.

Features

Run serverless inference for text, image, audio, video, transcription, and embedding models
Process large workloads asynchronously with Batch Inference
Deploy models on dedicated, single-tenant GPU infrastructure
Fine-tune open models with supervised fine-tuning and preference optimization
Run GPU clusters for training and inference workloads
Create secure code sandboxes and code interpreter sessions through an API
Use managed storage with parallel filesystems and no egress fees

Use cases

Build production AI applications with model APIs
Deploy coding, research, and customer-support agents
Fine-tune open models for domain-specific behavior
Process batch text, image, audio, or video workloads
Run training and inference jobs on managed GPU clusters
Add voice, media generation, or multimodal features to products
