Most buyers should pick OpenAI.
Choose OpenAI if you want a free ChatGPT tier, published individual prices from $8/month, or ChatGPT Business with per-user rates. Choose Azure OpenAI Service if you want Microsoft Foundry's model discovery-to-deployment path. The price gap is hard to quantify: Azure Standard and Batch rates are usage-based and not published here. Its 30-day, $200 credit is the general Azure Free Account offer, not an Azure OpenAI free plan. Compare expected token use before switching.

02Pricing compared
OpenAI has a free ChatGPT tier and published individual prices starting at $8/month for Go. Plus is $20/month; Pro plans are $100, $200 or $500/month. ChatGPT Business Standard is $25 per user monthly or $20 per user with annual billing; Premium is $125 monthly or $100 annually. Enterprise and Edu pricing is custom. These are ChatGPT prices, not API rates, which are not included on the vendor's site.
Azure OpenAI has no published monthly or annual price here. Standard is billed per token; Provisioned is billed per PTU-hour, and Batch is per token with a listed 50% discount on Global Standard pricing. The general Azure Free Account includes a 30-day trial and $200 credit, not a dedicated Azure OpenAI free plan. Compare expected token use before switching; the available figures do not establish which API will cost less.
03Features and depth
OpenAI combines ChatGPT, ChatGPT Business and an API Platform. Its homepage also presents AI research and announces models and products, including GPT-6.1 Terra and Images 2.6. ChatGPT plans vary in limits: the published pricing lists a 27K-token context window for Free, 54K standard context for Go and Plus, and 256K for reasoning on those paid plans. Plus includes advanced reasoning, deep research and custom GPTs; Business Premium lists five times Standard usage and no five-hour cap.
Azure OpenAI is listed within Microsoft Foundry Models. Microsoft describes Foundry as supporting model discovery from exploration through deployment, plus building and evaluating generative AI solutions and custom agents. The published Azure material does not give Azure OpenAI-specific model details, so we cannot compare its model selection or capabilities directly with OpenAI's. Its pricing information does distinguish Standard, Provisioned throughput and Batch workloads, with quotas and throttling applying.
04Ease of use and learning curve
For a person who wants a conversational tool, OpenAI makes the entry point clear: its homepage invites users to message ChatGPT, and the free tier is available. API use is a separate route, and the listed ChatGPT plans have different limits and usage caps to check before choosing.
Azure's documented route is through Foundry, which covers model exploration, evaluation and deployment. That may suit teams already building AI solutions in Azure, but the published information does not spell out Azure OpenAI setup steps or model-specific requirements. Pricing also needs more estimation: token usage, PTU allocation and possible throttling or spillover all matter. We would compare the workflow your team needs, not assume the two services have identical setup.
