## 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

## RTutor

RTutor, currently at version 2.00, is a browser-based tool from RTutor LLC (Orditus) that lets you analyze data by describing what you want in plain English. You upload a data file, and RTutor uses large language models to write R — or optionally Python — code, runs it, and shows you the results and the code side by side. The default model is now GPT-4o, and results can be downloaded as an HTML report within minutes.

The workflow is deliberately analyst-friendly. A row of tabs covers basic, categorical and numerical analysis, summaries, tables, correlation and GGpairs plots, plus a dedicated EDA reports tab. Within a session, previous questions and generated code become context for the next request, so you can ask to change a plot color or clean data step by step. A Q&A box lets you ask about the code, the result or an error message, and get guidance on methods or next steps. Uploaded data is loaded automatically into R as a data frame called df; a second file can be added as df2.

Privacy and use terms are spelled out clearly. By default, uploaded data is not sent to the model, though an option exists to include at most five random rows to improve coding quality; column names and data types are sent to guide generation, and uploaded data is deleted when the session ends. The website and source code are free for non-profit organizations only, and commercial use requires a license — businesses can arrange a custom, locally installed version. The developers also point heavier or messier workloads to their sibling platform, Datably.ai.

**Pricing & Plans:** Free for non-profit organizations (website and source code). Commercial use requires a paid license, and RTutor can be customized and locally installed. You can also supply your own OpenAI API key, with roughly $5/month often sufficient.

- **Natural language to R/Python:** Upload CSV, TSV or Excel files and request analyses in plain English; RTutor generates the R or Python code and executes it for you.
- **Guided analysis tabs:** Dedicated tabs for basic, categorical and numerical analysis, summary statistics, tables, correlation and GGpairs plots guide common workflows.
- **Downloadable EDA reports:** Generate multi-section EDA reports and download them as HTML documents in minutes.
- **Conversational iteration:** In a session, previous questions and generated code become context, so you can refine charts and clean data conversationally.
- **Built-in Q&A on code:** Ask about a result or error message and get methods, explanations or a plan for the next step.
- **Python mode & multi-file:** Switch to Python for code generation, or upload a second file as df2 to analyze datasets together.

**Strengths:** Analyze data by describing requests in plain English — no R syntax required; Runs generated code and returns results, plots and a downloadable HTML report; Context carries within a session, so you can refine charts and clean data conversationally; Guided tabs for EDA, distributions, tables and correlations speed up common tasks

**Limitations:** Generated code can be logically wrong even when it runs without error, so results need validation; Analyzes only traditional statistical data where rows are observations and columns are variables; Non-profit use is free but commercial use requires a paid license; By default a small random sample of rows is sent to OpenAI unless you opt out in settings
