• playground: Test, compare, and experiment with different models and parameters in an intuitive web-based Playground before writing a single line of code.
• 💰 Unbeatable Cost-Effectiveness: By focusing on open-source models and optimizing its hardware and software stack, Together AI offers some of the most competitive pricing on the market.

Transparent Pay-As-You-Go Pricing

Together AI champions a straightforward and developer-friendly pricing model. There are no complex subscription tiers or hidden fees; you simply pay for what you use. This makes it incredibly accessible for everyone from solo developers to large enterprises.

Text & Chat Models (per 1M tokens)

Pricing is based on the number of input and output tokens processed. For example:

• Mixtral-8x7B-Instruct: ~$0.60 / 1M tokens
• Llama-3-70B-Instruct: ~$0.90 / 1M tokens
• Gemma-7B-It: ~$0.20 / 1M tokens

Image Models (per image)

You are charged on a per-image-generated basis, making costs predictable.

• Stable Diffusion XL: ~$0.0008 per image (based on 1024×1024, 30 steps)

Note: Prices are examples and subject to change. Please refer to the official Together AI website for the most current rates.

Who is Together AI For?

The platform’s versatility makes it an ideal choice for a wide range of users:

• 🚀 AI Developers & Startups: Build and scale AI-powered applications quickly and affordably without the headache of managing infrastructure.

• 💼 Enterprises: Integrate powerful, customizable, and cost-effective AI into existing workflows and products while maintaining data privacy through fine-tuning.
• 🧑‍💻 Data Scientists: Easily fine-tune and deploy custom models for specialized tasks like sentiment analysis, document classification, and more.
• 🎨 Creatives & Hobbyists: Access powerful generative tools through a simple API to fuel creative projects.

Alternatives & How Together AI Compares

The AI infrastructure space is competitive, but Together AI has carved out a distinct niche.

• Vs. Proprietary Models (OpenAI, Anthropic): While platforms like OpenAI offer highly capable models, they operate as black boxes with premium pricing. Together AI offers transparency, customizability through fine-tuning, and significantly lower costs by championing the open-source ecosystem.
• Vs. Other OS Model Platforms (Replicate, Anyscale, Fireworks AI): Together AI’s primary differentiator is its relentless focus on performance. Its custom inference stack often provides superior speed and lower latency compared to competitors. While a platform like Replicate might offer a wider range of niche community models, Together AI curates a selection of the most robust and popular models and optimizes them for maximum throughput.
• Vs. Cloud Giants (AWS Bedrock, Google Vertex AI): Major cloud providers offer access to some open-source models, but often with more complex pricing and less performance optimization. Together AI is purpose-built for one thing: running generative AI at peak efficiency, making it a more streamlined and often more cost-effective solution.

In conclusion, the Together AI Model Library is an exceptional resource for anyone looking to build with open-source AI. It masterfully combines variety, bleeding-edge speed, and disruptive pricing into a single, cohesive platform that empowers the next wave of AI innovation.
