OpenAI vs Inference.net

Inference.net sells a path off closed APIs: route traffic, capture it, then distill a smaller model. It can sit in front of OpenAI before replacing parts of it.

OpenAI vs Inference.net: key differences

Inference.net positions itself as the exit ramp from APIs like OpenAI's. Its Inference Gateway routes traffic to open, closed or custom models under one key and captures every request, turning that traffic into eval and training datasets. From there it fine-tunes a task-specific model and deploys it on a dedicated GPU with a 99.99% uptime target. The target is a narrow GPT-class workload that a smaller model can handle with lower cost and latency. OpenAI's broad lineup, from Luna to Astra, stays the source of general capability.

For bulk jobs, both sell batch. OpenAI's Batch halves every price. Inference.net's OpenAI-compatible Batch API takes up to 1M requests per file, with completion windows from 24 hours to 7 days, running on spare GPU capacity it buys at steep discounts. The trade-off is evidence: few independent benchmarks or public pricing comparisons exist, so buyers depend on Inference.net's own numbers, while OpenAI publishes its costs per tier. A sensible pattern keeps OpenAI for open-ended work and tests Inference.net on one high-volume, narrow task.

What OpenAI and Inference.net do

OpenAI

OpenAI runs the most widely adopted closed-model API. Its September 2026 lineup has GPT-6 Astra at the top for computer use, coding and long agentic runs, priced at $10 in and $50 out per million tokens. Below it sits the GPT-5.6 family: Sol for hard professional work, Terra as the balanced default, and Luna for high-volume jobs at $0.20 in and $1.20 out. All of them carry a 1.05M token context window with up to 128K output.

Example models: GPT-6 Astra, GPT-5.6 Terra

Inference.net

Inference.net started as a buyer of last resort for idle GPU time. Its scheduler aggregates small unused chunks of capacity across data centers and runs models on them, and it passes the steep discounts it gets from those data centers on to customers. That origin still shows in its OpenAI-compatible Batch API, which takes up to 1M requests per file with completion windows from 24 hours to 7 days and far higher headroom than synchronous limits.

Example models: open catalog models plus customer fine-tunes served on dedicated GPUs
