## 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

## TopicMojo

TopicMojo describes itself as a topic and question research tool combined with a search listener. Its job is to tell you what people are talking about around any given query, so you can decide what content to create. It draws on more than 50 data sources and 10+ social platforms, spanning Reddit, Twitter, Pinterest, TikTok and Instagram, and presents the findings in a single dashboard with links back to the source material.

The toolkit is organized into a few core models. The Topic Model fetches data from across the web for any subject you enter and supports saved lists, workspaces, custom domains, export options and report sharing. The Question Finder gathers the questions people ask about your topic so you can understand their needs, and the Search Listener highlights new and unique searches so you can be first to cover them. A social model builds a parallel view across social platforms.

TopicMojo also reaches into content production with a blog post idea and outline generator, an AI content tool, Instagram and TikTok hashtag generators, and a Humanize feature. An SEO add-on adds depth with search volume and trends, sentiment and hype, and CPC and PPC difficulty. Research can be run in 35+ languages for 215+ countries, with team collaboration, CSV export and 30-day report history, and plans start at around $10 per month with a 7-day money-back guarantee.

**Pricing & Plans:** Freemium / paid: a free trial is available, and paid plans start at around $10 per month with monthly or yearly billing, a limited-time 50% discount, a 7-day money-back guarantee, and an optional SEO add-on.

- **Topic Model:** Build a topic model that pulls data from across the web for any subject, with saved lists, workspaces, custom domains, exports and shareable reports.
- **Question Finder:** Gather the questions people actually ask around your topic across the web so you can understand real intent and answer it.
- **Search Listener:** Be first to cover new and unique searches around a query with the Search Listener tool.
- **Social model:** Build a social model across Reddit, Twitter, Pinterest, TikTok, Instagram and 10+ platforms to see what people are talking about.
- **AI content & hashtag tools:** Blog post idea and outline generators, an AI content tool and Instagram/TikTok hashtag generators to move from research to publishing.
- **SEO data add-on:** An SEO add-on provides search volume, trends similarity, sentiment, hype, CPC and PPC difficulty to help you rank higher on Google.

**Strengths:** Aggregates 50+ data sources and 10+ social platforms in one dashboard; Question Finder and Search Listener surface real intent and emerging searches; Supports 35+ languages and 215+ countries; Includes AI content, outline and hashtag generators for content production

**Limitations:** The 50% off promotion is a limited-time teaser, so standard pricing applies after it ends; Some SEO data such as search volume and PPC difficulty is an add-on rather than core; Rich reporting features and saved lists are most valuable on paid plans; As a research and idea tool it does not publish or host finished content for you
