## 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

## SpellBox

SpellBox is an AI coding assistant built around a simple idea: describe the problem you are solving and let the tool write the code. Instead of losing time to syntax errors, algorithm searches and documentation hunting, you type a prompt and get a solution back, then iterate from there. It is aimed at professional engineers as much as students and hobbyist coders.

Beyond generation, SpellBox adds two practical features. Code explanation takes code you did not write, or code you wrote weeks ago, and gives you a quick breakdown so you can pick up unfamiliar logic fast. Code bookmarking stores snippets you generate so you can retrieve the same solution when a similar problem shows up in another project.

SpellBox runs as a desktop app on macOS and Windows, and also integrates with VS Code and JetBrains IDEs so you can stay in your editor. It supports major programming languages, and the examples on the site include orbital mechanics in C++, quadratic equations in MATLAB and common Python problems. Licensing is a one-year purchase with unlimited generation, and the site notes a 5-day refund window.

**Pricing & Plans:** One-year license priced around $40 during the promotional early-bird period (list price about $65), including unlimited code generation, use on unlimited computers and code bookmarking. A 5-day money-back guarantee applies, and an extra promo code discount has been offered historically.

- **Code generation:** Describe what you need in plain language and SpellBox writes the code for you.
- **Code explanation:** Paste in existing code and get a fast explanation, so you can understand unfamiliar logic without deep documentation dives.
- **Code bookmarking:** Save snippets you generate and retrieve them later, useful when juggling multiple projects.
- **Editor extensions:** Use SpellBox inside VS Code or JetBrains IDEs instead of switching to a separate app.
- **Multi-language support:** Works across major programming languages including C++, Python, JavaScript and MATLAB.

**Strengths:** Handles generation, explanation and snippet storage in one tool; Available as desktop apps plus VS Code and JetBrains integrations; One-year license with unlimited code generation and no per-seat computer limit; Supported across major languages from Python to C++ and MATLAB

**Limitations:** Purchase is a one-year license rather than a perpetual or low-cost monthly plan; The publicly listed promotional pricing dates back to late 2024, so current pricing should be confirmed at checkout; No large public free tier beyond downloading and trying the apps
