## 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

## Topicfinder

Topicfinder is built for content teams that compete hard for organic traffic. It starts from your competitor set: instead of checking one domain at a time in a browser tab, it crawls many competing websites at once, then pulls SEO and traffic statistics from a range of external APIs and displays them next to every topic it finds. The result is a large, sortable pool of candidate topics rather than a handful of manual searches.

Organization is a core part of the pitch. Each project lives in your account, so you can run reports at any hour on Topicfinder's servers, then filter and refine later. Exports are equally bulk-friendly — grab SEO insights on hundreds of competitor pages in seconds, or email reports to your team instead of merging spreadsheets by hand.

Where AI comes in is the last mile: once you've selected a topic, Topicfinder generates optimized article title variations automatically and scores them by SEO potential and length, marking green ones as ready to use. The tool is made by a content marketing agency that publishes hundreds of longform articles monthly, and a free trial is available before you commit to a paid plan.

**Pricing & Plans:** Free trial plus paid plans. You can start with a free trial at app.topicfinder.com/trial and upgrade to a paid subscription for ongoing reports and projects. Exact tier prices are not published on a public page we could verify, so confirm current pricing in the app.

- **Bulk competitor crawling:** Enter a competitor and Topicfinder crawls thousands of related sites in parallel, surfacing their best-performing pages instead of making you check one domain at a time.
- **SEO data beside every topic:** Real-time SEO metrics and traffic statistics are pulled from multiple APIs and shown next to each topic you find, so you can judge value at a glance.
- **Filters, organization and exports:** Sort, filter and refine results with smart filters, keep everything organized in your account, and export hundreds of competitor pages in seconds or email reports to your team.
- **AI title generation:** After you pick a topic, Topicfinder generates optimized title variations automatically and scores them by SEO potential and length, flagging ready-to-use options in green.
- **Server-side, multi-threaded speed:** Reports run on Topicfinder's servers around the clock with multi-threaded parallel processing, so research completes fast without dozens of open browser tabs or spreadsheets.

**Strengths:** Finds far more competitor topics than manual, one-domain-at-a-time research; Real-time SEO and traffic data sits right next to each topic idea; AI title suggestions scored for SEO potential and length; Built-in organization and bulk exports replace spreadsheets and endless tabs

**Limitations:** Cloudflare-style protection can block automated access and some third-party tooling; To get value you need to configure projects and filters — it is not a one-click tool; Requires several external SEO data sources/APIs, which can add cost at scale; Title generation suggests ideas but you still edit and publish the content yourself
