## OpenAI Platform

While ChatGPT serves end users, openai.com and the OpenAI Developer Platform (developers.openai.com) provide the foundational API, SDKs, and enterprise infrastructure powering thousands of production AI applications worldwide. In late 2026, OpenAI's API catalog is anchored by the GPT-6 and GPT-6.1 model suite—all featuring a 1.05-million-token context window and up to 128K output tokens. The lineup spans GPT-6 Astra for frontier reasoning and mission-critical research, GPT-6.1 Sol for near-Astra intelligence at one-fifth the price, GPT-6.1 Terra for fast visual reasoning and computer use, and GPT-6 Luna for ultra-high-volume, low-latency tasks, alongside specialized models like `gpt-5.3-codex` and `gpt-6-astra-law`.

The OpenAI Platform has evolved well beyond basic chat completion endpoints. Through the unified `v1/responses` API, developers can orchestrate stateful multi-step agents equipped with built-in server-side tools—including live web search, vector file search, code interpreter sandboxes, and GUI computer use—without stitching together external orchestration frameworks. Every flagship model supports configurable reasoning effort (`none`, `low`, `medium`, `high`, `xhigh`, and `max`), strict JSON schema Structured Outputs, and multimodal image/audio inputs, while `gpt-live-1` powers per-second billed speech-to-speech voice agents.

OpenAI bills API usage on a transparent consumption model scaled across usage tiers (Build, Launch, and Grow, scaling up to 40M+ tokens per minute). In 2026, aggressive price cuts on the 6.x generation dropped entry-level intelligence on GPT-6 Luna to $0.10 per million input tokens and $0.50 per million output tokens, while GPT-6.1 Sol runs at $2/$10 and flagship GPT-6 Astra sits at $10/$50. Engineering teams can cut spend by 90% on repeated context using automatic Prompt Caching, save 50% on asynchronous workloads via the Batch API, and enforce regional data residency with a 10% compliance uplift.

**Pricing & Plans:** Usage-based pay-per-token API billing: GPT-6 Astra at $10/1M input and $50/1M output tokens; GPT-6.1 Sol at $2/1M input and $10/1M output; GPT-6.1 Terra at $1/1M input and $5/1M output; GPT-6 Luna at $0.10/1M input and $0.50/1M output; GPT-Live-1 voice at $0.05/minute; 90% discount on cached inputs and 50% off via Batch API.

- **GPT-6 & GPT-6.1 Model Lineup with 1.05M Context:** Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
- **Configurable Reasoning Effort Controls:** Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
- **Responses API & Native Computer Use Tools:** Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
- **GPT-Live-1 Realtime Voice API:** Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
- **90% Prompt Caching Discount & Batch API:** Cached input tokens bill at just 10% of standard input rates, while asynchronous 24-hour Batch API jobs cut both input and output token costs by 50%.

**Strengths:** 100-fold cost flexibility from GPT-6 Luna ($0.10/$0.50 per 1M tokens) up to frontier GPT-6 Astra ($10/$50 per 1M tokens); Unified 1.05M-token context window and 128K output limit across the entire flagship GPT-6 and GPT-6.1 family; 90% discount on cached input tokens and 50% Batch API discount dramatically reduce production inference bills; Industry-standard SDKs, Structured Outputs, and built-in Responses API tools minimize boilerplate agent code

**Limitations:** Long-context requests exceeding the standard window threshold trigger roughly 2x higher per-token billing rates; Flagship GPT-6 Astra ($10 input / $50 output per 1M tokens) is significantly more expensive than Claude Opus 5.5 ($4/$20) and Grok 4.7 ($2/$6); Regional data residency endpoints incur a 10% price uplift on models released after March 2026

## Promi

Promi addresses a familiar ecommerce trade-off: discounts lift conversion but erode margin, and most stores solve it with one blunt sitewide promotion. Promi instead personalizes discount depth shopper by shopper and product by product. Its AI model ingests signals such as visitor views, traffic source and transaction history to estimate how price-sensitive a given shopper is, then applies the smallest offer likely to close the order — factoring in the product's profit margin and conversion rate so the discount does not simply give away profit on items that would have sold anyway.

On top of the model, Promi gives merchandisers direct control over who sees what. You can build targeting logic around views, orders, traffic sources, UTM parameters and tags — for example member-only discounts or offers shown exclusively to paid ad traffic — and then choose how the discount surfaces: automatic price strikethroughs, pop-ups, or discount descriptions that appear when a visitor follows a link. Klaviyo and similar CRM integrations extend the same personalization into email. Every campaign can be measured through built-in A/B tests covering revenue, gross profit and conversion rate, with raw experiment data available for export.

The company positions itself for both small stores and nine-figure brands, and publishes case studies reporting average increases of +24% revenue per visitor, +22% gross profit, +26% conversion rate and +20% ARPU. It is a B2B platform sold primarily through demos rather than self-serve signup, which makes sense given that the AI model needs your own traffic data to become useful. The site offers a 40-second discount analysis to give prospective customers a first read on their current promotion strategy.

**Pricing & Plans:** Promi offers a free trial and paid plans; pricing is discussed during a demo rather than published as a fixed self-serve rate card. Book a demo or contact the team for current plan details.

- **AI price-sensitivity model:** Promi's model uses visitor views, traffic source, transaction history and more to estimate price sensitivity, then sets discount depth at the individual product level with margin and conversion rates taken into account.
- **Custom targeting rules:** Define who sees an offer — members only, ad traffic only, specific UTM campaigns or tag-based segments — instead of discounting every visitor.
- **Flexible discount display:** Trigger price strikethroughs, pop-ups and discount descriptions automatically or on link click, with Klaviyo and similar CRM integrations for email offers.
- **Built-in A/B testing:** Run A/B tests measuring revenue, gross profit, conversion rate and more, and export the experiment data for your own analysis.
- **Documented performance:** The platform reports average uplifts of +24% revenue per visitor, +22% gross profit and +26% conversion rate across the small stores and $100M+ brands it works with.

**Strengths:** Optimizes at the individual shopper and product level rather than with blanket codes; Targeting rules and display formats give merchandisers direct control over offers; Built-in A/B testing with exportable data makes margin impact measurable; Integrates with Klaviyo and similar CRM tools for personalized email discounts

**Limitations:** The AI model needs enough traffic and transaction history to be effective, so very new or low-traffic stores may see limited benefit; Sold through demos rather than self-serve, and standard list pricing is not published; Setup involves configuring targeting rules and discount display, which takes some marketing effort
