Together AI doesn't publish results. It said its annual bookings crossed $1.15B in the quarter before July 2026, and Sacra estimated a $1B run rate in February 2026.

A run rate is a month's revenue times twelve and isn't audited revenue. Together AI hasn't given a run rate of its own, and bookings are a different measure.
How Together AI makes money
Together AI sells computing for open AI models. Its pricing page lists serverless inference, dedicated endpoints, fine-tuning and GPU clusters, with a free start.
Sacra estimates a gross margin of about 45%, and expects owning GPUs to improve it. Sacra also says the HUMAIN deal brings 250 MW of power and 120,000 chips. By Sacra's account, Together expects $5B in annual business from it once fully deployed.
- Per-token API. Developers pay by the token to run open models. Sacra counts this as one of two main revenue lines, with GPU server rentals. Sacra
- Batch API. Priced at 50% below real-time inference rates, according to Sacra. Sacra
- GPU rentals. Instant Clusters cost $1.76 to $2.39 per GPU-hour for HGX H100 and $4.00 to $5.50 for HGX B200, by Sacra's figures. The price depends on commitment length. Sacra
- Data center deals. In August 2026 it announced a partnership with HUMAIN that includes a new 250 megawatt data center in Saudi Arabia. Business Wire
