## How they compare

RunInfra is a 2026 startup with two products. Its Model APIs serve a small set of mid-size models, like Nemotron 3.5 Lightning 30B and Qwen 3.8 27B, through one key that works with OpenAI and Anthropic SDKs, with coding plans from $10 a month. Its second product is an agent that takes a plain-English endpoint request, benchmarks GPUs from L4 to B200, searches quantized variants and ships an endpoint that scales to zero with cold starts under two seconds. Together serves frontier-scale open models such as Kimi K3 and DeepSeek V4 across thirty-plus text models.

Quality ceiling and track record favor Together. RunInfra's own downsides note its library is far from frontier quality and it has little independent benchmarking. Together adds managed LoRA, full SFT and RL, provisioned throughput with a 99% SLA and reserved clusters. RunInfra fits small teams without ML ops staff who want a tuned mid-size model or a voice pipeline chaining Whisper, an LLM and TTS, and developers wanting a cheap model in Claude Code or Codex. Together fits heavier production and training work.

## 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.

### RunInfra

RunInfra pitches open models built for agents, with two ways in. Its hosted Model APIs serve a small curated library, including Nemotron 3.5 Lightning 30B, Qwen 3.8 27B and Ornith 1.5 35B, behind one key that works with both the OpenAI and Anthropic SDKs. Cached context bills at a discount. Coding plans start at $10 a month with limits that reset every five hours and every week, and they plug into Claude Code, Codex, OpenCode, Cline, Aider and dozens of other agent CLIs.
