Our verdict

OpenAI serves teams that want chat, realtime, image and transcription models from a single vendor behind an OpenAI-compatible API, rather than routing several providers. Developers standardising on a single interface get real breadth, but entry cost runs high: input price runs $0.10 to $10 and output $0.50 to $50.

Pros and cons

Pros

  • gpt 6 astra, gpt 6 sol and gpt 6 luna covers text, realtime, image and speech, so a single vendor serves the whole stack.
  • Buyers with a vendor security review have SOC 2 Type 2, ISO/IEC 27001:2022 and ISO/IEC 27017 to point at.
  • Existing OpenAI-compatible clients keep working, so migration work stays small.

Cons

  • Input price runs $0.10 to $10 against Salad's $0.06 entry rate, and output reaches $0.50 to $50.
  • Support runs on email, help centre and community only, so there is no phone or live chat route.

Who it suits

  • Teams that need text, realtime, image and speech models from gpt 6 astra, gpt 6 sol and gpt 6 luna in one place.
  • Organisations whose vendor review requires SOC 2 Type 2, ISO/IEC 27001:2022 and ISO/IEC 27017.
  • Procurement teams comfortable contracting with a US entity, OpenAI OpCo, LLC.

Who should look elsewhere

  • Azure AI Foundry, if catalogue breadth across gpt 6 astra, gpt 6 luna and gpt 6 sol matters more than a single vendor relationship.
  • Salad, if the entry rate decides it: $0.06 starts below $0.10 to $10.
  • Supascale AI, if DeepSeek V4 Pro, GPT 5.6 Sol and GPT 5.6 Terra is closer to the mix you need.

Core features

The catalogue covers text, realtime, image and speech. gpt 6 astra, gpt 6 sol and gpt 6 luna lists gpt-6-astra, gpt-6-sol and gpt-6-luna alongside gpt-live-1, gpt-realtime-translate, gpt-image-2.5-sunburst, gpt-transcribe and gpt-4o-transcribe. Largest context window is 1,050,000. The API is OpenAI-compatible, so existing clients and SDK calls stay as they are.

The company behind it

The contracting entity is OpenAI OpCo, LLC, headquartered in the US and founded in 2015. Support runs on email, help centre and community, which puts documentation and community answers ahead of direct contact for routine questions. Buyers needing a named counterparty get one, though everyday help arrives through self-service channels.

Frequently asked questions

What does it cost to run a prompt through the API?+

Pay per token, and the spread across the catalogue is wide. Input price runs $0.10 to $10 and output price runs $0.50 to $50, so a small model for classification and a heavy one for long answers sit at very different rates. Cheaper gateways such as Salad start at $0.06.

Which models can I call?+

gpt 6 astra, gpt 6 sol and gpt 6 luna is the full list, and it spans text models such as gpt-6-astra and gpt-6-sol, realtime and live variants, image generation, and a run of transcription endpoints including gpt-transcribe and gpt-4o-transcribe. Speech, vision and text therefore come from the same vendor.

How large is the largest context window?+

The top of the range is 1,050,000, which is a model limit rather than a plan limit. On the site that places OpenAI at 5 of 72 brands ranked on largest context window, so the headline window is wide without being the widest in the group.

Is the API OpenAI-compatible?+

The API is OpenAI-compatible, so existing client libraries, function calling and prompt code written against OpenAI keep the same request shapes. The same interface serves everything in gpt 6 astra, gpt 6 sol and gpt 6 luna, from gpt-6-astra through the realtime and transcription endpoints, so there is little to rewrite.

How do I get help?+

Support runs on email, help centre and community. Routine questions, billing queries and account changes are handled through the help centre and the community forum, with email as the written escalation route. A phone line or live chat is not part of the listed channels, so time-sensitive issues go through email.

What certifications does OpenAI hold?+

The published set is SOC 2 Type 2, ISO/IEC 27001:2022 and ISO/IEC 27017. That covers the frameworks most vendor security reviews ask for, spanning audit and control standards, data protection standards, an AI management standard, payment data handling and cloud controls. Teams that need a documented compliance baseline have it on record before signing.

Who am I actually contracting with?+

Terms are with OpenAI OpCo, LLC, a US entity founded in 2015. That matters for procurement, since the contract, the security documentation and the invoices all sit with a single named company rather than a reseller, which usually shortens vendor onboarding for regulated teams.

How does the model list compare with Azure AI Foundry?+

Azure AI Foundry sells gpt 6 astra, gpt 6 luna and gpt 6 sol directly, which is a wider catalogue for pure model shopping. OpenAI's own list is narrower but self-contained, with every model arriving under the same API and certification record.
