## How they compare

DeepInfra wins the per-token contest. Llama 3.1 8B runs $0.02 per million and DeepSeek V4 Flash $0.14 in and $0.28 out, with no minimums or contracts across 150+ models. Part of that edge is quantization: DeepInfra serves DeepSeek V4 Pro in FP4 with context capped at 66K, 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 has RL in beta, 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 each one does

### 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 past thirty open models, including DeepSeek V4, Kimi K3, GLM 5.2, Qwen 3.8 and MiniMax M3, plus image, video, speech and embedding models. Token prices sit at parity with Fireworks and Baseten.

### DeepInfra

DeepInfra is the price floor for open-model inference. Developers treat it as the reference point for what a token should cost, with small models like Llama 3.1 8B at $0.02 per million and DeepSeek V4 Flash at $0.14 in and $0.28 out. The catalog covers 150+ open models across text, image and speech behind a fully OpenAI-compatible API. There are no minimums, setup fees or contracts on the shared API.
