## How they compare

RunInfra is a young company with two products. Its hosted Model APIs serve a small library of mid-size models such as Nemotron 3.5 Lightning 30B and Qwen 3.8 27B, with coding plans from $10 a month for Claude Code, Codex and other agent CLIs. Its deployment agent takes a plain-English spec, benchmarks GPUs from L4 to B200, searches quantized variants and ships an endpoint that scales to zero with cold starts under two seconds. Cerebras skips configuration entirely and sells speed on its own chip, with GPT-OSS 120B near 3,000 tokens per second.

Both catalogs are small, so the decision turns on the job. RunInfra suits developers who want a flat-rate open model inside a coding tool, and small teams that need a tuned endpoint or a Whisper, LLM and TTS voice pipeline without ML ops staff. Cerebras suits teams whose users feel every token, such as voice agents and live autocomplete. RunInfra has little independent benchmarking or enterprise track record. Cerebras, founded in 2015, has OpenAI renting about 750 MW of its capacity.

## What each one does

### Cerebras

Cerebras builds a single chip the size of a silicon wafer, and its inference cloud is the fastest public host on the models it serves. Its developer table lists GPT-OSS 120B near 3,000 tokens per second, about six times Groq on the same weights, at $0.35 in and $0.75 out per million. The public shared catalog is thin, just GPT-OSS 120B and Gemma 4 31B as of August 2026. More model families live on dedicated endpoints and through partners like OpenRouter, Hugging Face, Vercel and AWS Marketplace.

### 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.
