Together AI is the company you call when you've fallen in love with an open-weight model and need it in production by Friday.
Inference: their serving stack is among the fastest for Llama, Qwen, DeepSeek and friends. They publish benchmarks vs. other providers regularly — and they usually win on throughput and price per token.
Fine-tuning: LoRA and full fine-tuning on your data, without managing GPUs. Upload your dataset, pick the base model, get back an adapter and a serving endpoint.
Model deployment: dedicated endpoints for your custom models. Pay per hour or per token.
The honesty: their support for very new models can lag by a week or two after release — they have to validate and optimize each one.
What we run there: Qwen2.5-Coder-32B for our coding assistant evals, and DeepSeek-V3 as a cost-effective Claude alternative for internal tools.
Who this is for: teams committed to open weights that don't want to run their own GPU cluster. Together is the fastest path from model card to production API.
