OpenAI launches Decisions API (public beta) using gpt-6-luna
OpenAI introduced the Decisions API in public beta, a service that evaluates text, images, or both and returns structured outputs (yes/no probabilities, category picks, or scale ratings). It uses only gpt-6-luna, is roughly ten times faster than the Responses API, charges $0.10 per million input tokens (output tokens free), supports zero-data retention and HIPAA-compliant use in the US and Europe, and comes alongside a simplified paid tiering (Build, Launch, Grow) with $500/$5,000/$200,000 monthly thresholds.
KEY POINTS
- OpenAI introduced the Decisions API in public beta, a service that evaluates text, images, or both and returns structured outputs (yes/no probabilities, category picks, or scale ratings).
- It uses only gpt-6-luna, is roughly ten times faster than the Responses API, charges $0.10 per million input tokens (output tokens free), supports zero-data retention and HIPAA-compliant use in the US and Europe, and comes alongside a simplified paid tiering (Build, Launch, Grow) with $500/$5,000/$200,000 monthly thresholds.
- This provides a faster, purpose-built API for structured decisioning that can reduce latency and cost for classification and routing tasks and signals OpenAI's push toward specialized decision models and clearer pricing tiers.
DECISION BRIEF
CONFIDENCE
WHAT CHANGED
OpenAI launched a public-beta Decisions API that evaluates text, images, or both and returns structured outputs (yes/no probabilities, category picks, or scale ratings). It currently supports only the gpt-6-luna model, is described as about ten times faster than the Responses API, and charges $0.10 per million input tokens (output tokens reported as free). OpenAI also simplified paid API tiers to three levels—Build, Launch, Grow—with monthly thresholds of $500, $5,000, and $200,000.
WHY NOW
The Decisions API packages classification-style outputs (yes/no, picks, scales) with a faster, lower-cost per-input pricing and data-retention/HIPAA options; this directly targets common tasks named in coverage (damage-photo detection, customer inquiry routing, document classification) and aligns with media coverage of a broader shift toward specialized decisioning and multimodal GPT-6 features.
WHO IS AFFECTED
Directly affected: developers and organizations that build classification, routing, or image-evaluation pipelines on OpenAI’s APIs; healthcare-related users in the US and Europe who require HIPAA-compliant processing; any customers whose billing crosses the new Build/Launch/Grow thresholds.
CONFIRMED
- OpenAI announced a Decisions API in public beta that evaluates text, images, or both and returns structured outputs (yes/no probabilities, picks from categories, scale ratings). - The Decisions API currently supports only gpt-6-luna. - OpenAI says the Decisions API runs about ten times faster than the Responses API. - Pricing reported: $0.10 per million input tokens; output tokens are reported free. - The Decisions API handles three response types: yes/no probabilities, predefined-category picks, and scale-based ratings. - The API is described as supporting zero-data retention and HIPAA-compliant use in the US and Europe. - OpenAI reduced paid API tiers to three (Build, Launch, Grow) with monthly thresholds of $500, $5,000, and $200,000. - Media coverage separately documents OpenAI’s GPT-6 rollout and new multimodal/visual Intelligent UI in ChatGPT.
UNCERTAIN
- No firm general-availability date for Decisions API is provided in the excerpts (The Decoder says GA is "coming soon" but gives no date). (missing) - The "about ten times faster" claim lacks benchmark details in the excerpts (no latency numbers, workloads, or test methodology provided). (missing) - It is not specified whether gpt-6-luna is the same GPT-6 variant used in the ChatGPT Intelligent UI coverage; the relationship between ChatGPT’s GPT-6 rollout and the gpt-6-luna Decisions model is not detailed. (potentially incomplete/conflicting) - Scope and conditions for the stated zero-data retention and HIPAA compliance are not detailed (e.g., whether these apply by default, require enterprise contracts, or have regional caveats). (missing) - The long-term pricing model (whether output tokens remain free beyond beta) and whether more models will be supported later are not stated. (missing)
WHAT TO WATCH
Concrete observable signals to watch next: - Official OpenAI documentation or blog post with GA date and full technical/benchmarked performance numbers for Decisions vs Responses. - API docs noting supported models beyond gpt-6-luna or variant mapping to ChatGPT’s GPT-6. - Published security/compliance documentation that clarifies zero-data-retention and HIPAA terms. - Billing/product pages or changelogs confirming whether output tokens remain free and any pricing updates. - Case studies, customer announcements, or partner integrations using Decisions API for named use cases (damage detection, routing, classification). - Any public benchmarks or independent tests measuring latency, throughput, and accuracy for Decisions API.
WHY IT MATTERS
This provides a faster, purpose-built API for structured decisioning that can reduce latency and cost for classification and routing tasks and signals OpenAI's push toward specialized decision models and clearer pricing tiers.

SOURCES & TIMELINE
3When you ask a chatbot a question, you’ll often get a wall of text back, maybe with an image or two pulled from the web. That may no longer be the case soon as OpenAI overhauls how ChatGPT answers prompts. On Wednesday, OpenAI unveiled an “Intelligent UI” update for ChatGPT that generates visual, custom elements—when helpful—for answering a user's questions. The company's new experience is powered by its recent GPT-…
ChatGPT is about to get a lot more visual, thanks to a new feature that OpenAI calls Intelligent UI. The new interface, which is being rolled out with a new GPT-6 model, will integrate a significant amount of visuals into users’ conversations. OpenAI says many of those visuals will be interactive. In other words, instead of just flat, cartoonish pictures, the chatbot will frequently include things like tappable butt…
OpenAI announced two updates to its API platform. The new Decisions API evaluates text, images, or both, running about ten times faster than the Responses API. It's in public beta now, with general availability coming soon. Only gpt-6-luna is supported so far, at $0.10 per million input tokens. Output tokens are free. The API handles three response types: yes/no probabilities, picks from predefined categories, and s…
