## 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

## reAlpha

reAlpha is a real-estate technology company that applies AI to the homebuying process. Rather than a conventional brokerage, its consumer platform is built around a zero-commission model in which buyers work with a virtual real estate agent and AI-assisted search instead of paying a traditional buyer's agent fee.

The idea is to compress the cost and friction of buying a home. Buyers search listings, narrow down options with AI-matched recommendations, and receive guidance from a virtual agent through offers and closing. By removing the commission layer, the company positions itself as a lower-cost route to homeownership.

Because reAlpha is a publicly traded company, it also operates as an investment vehicle for real-estate technology, and its website presents both consumer-facing homebuying services and corporate/investor information. Coverage and program details vary by US market, so buyers should confirm current terms for their state on the official site.

**Pricing & Plans:** Positioned as a zero-commission homebuying platform: buyers are not charged a traditional buyer-agent commission. Transaction, financing and closing costs still apply, and program terms vary by market. Confirm current terms on the official website.

- **Zero-commission homebuying:** The platform is built to remove traditional buyer-agent commission from the purchase, keeping more equity with the buyer at closing.
- **Virtual real estate agent:** A virtual agent handles guidance across search, offers and closing instead of requiring an in-person buyer's agent.
- **AI-driven property search:** AI models analyse listings and buyer preferences to surface homes that fit budget, location and lifestyle.
- **End-to-end buying workflow:** Buyers get support through the full transaction, from initial search to closing, inside a single platform.

**Strengths:** Aims to cut buyer-agent commission to zero; AI-driven search can speed up home discovery; Virtual agent provides guidance without in-person showings; Backed by a publicly traded real-estate technology company

**Limitations:** Site is behind bot verification, so pricing and current feature details are hard to confirm; Service coverage is limited to specific US markets; Buying and selling incentives can vary by state and program terms; Commission-free models may still involve other transaction and closing costs
