Together AI vs DeepInfra: key differences

DeepInfra wins the per-token contest. Llama 3.1 8B runs $0.02 per million and DeepSeek V4 Flash $0.09 in and $0.18 out, with no minimums or contracts across 200+ models. Part of that edge is quantization: OpenRouter tags some DeepInfra endpoints as FP4, and reviewers report weaker output unless they pin FP8. Together prices at parity with Fireworks and Baseten, not at the floor. In return it offers a fuller platform: provisioned throughput with a 99% SLA, dedicated deployments with canary and shadow-traffic rollouts, and raw GPU clusters.

Training is the sharpest split. DeepInfra has no managed fine-tuning, so custom models get trained somewhere else. Together runs LoRA and full SFT from $0.48 per million training tokens and RL through Together Post-Training, with checkpoints that deploy straight to inference. For bulk tagging, extraction and synthetic data where cost per token dominates, DeepInfra is the natural pick, after checking precision per model. For production systems that need custom weights or rollout controls, Together fits better.

What Together AI and DeepInfra do

Together AI

Together AI is the broadest open-model platform in the category. One bill covers per-token serverless inference, batch at up to 50% off, provisioned throughput with a 99% SLA, dedicated deployments, raw GPU clusters, managed fine-tuning and code sandboxes for agents. The text catalog runs to about 20 open models, including GLM 5.3, DeepSeek V4.1 Flash, DeepSeek V4 Pro 0813, Kimi K3, Qwen 3.8 Flash and MiniMax M3.1 Flash, plus image, video and speech models. Token prices sit at parity with Fireworks and Baseten.
