OpenAI vs DeepInfra: key differences
At the budget end, OpenAI's cheapest tier, GPT-6 Luna, costs $0.10 in and $0.50 out per million tokens before discounts. DeepInfra serves DeepSeek V4 Flash at $0.09 in and $0.18 out and small models like Llama 3.1 8B at $0.02, with no minimums or contracts. For bulk extraction, tagging and synthetic data, that gap adds up quickly. OpenAI narrows it with Batch at half price and cached input at 10% of list, and Luna keeps the full 1.05M window that every GPT tier carries.
DeepInfra's savings come with conditions. Much of its price edge comes from quantization, which can cut context on some endpoints. Some reviewers report weaker output unless they pin FP8 variants, and there is no managed fine-tuning. OpenAI costs more, but a team gets full context, hosted tools and the Agents SDK. The right answer is often both: DeepInfra for high-volume, low-stakes calls where precision has been checked per model, and OpenAI for customer-facing and multi-tool work.
What OpenAI and DeepInfra do
OpenAI
OpenAI runs the most widely adopted closed-model API. Its October 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 sit GPT-6.1 Sol, the default for coding, research and computer use at $2 in and $10 out, and GPT-6 Luna for high-volume jobs at $0.10 in and $0.50 out. All three carry a 1.05M token context window with up to 128K output.
Example models: GPT-6 Astra, GPT-6.1 Sol, GPT-6 Luna

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 $0.09 in and $0.18 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.
