## 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

## OpenRepli

OpenRepli is a small Chrome extension aimed at one repetitive job: writing comments and replies on social networks. Instead of switching tabs to a chatbot, you click the OpenRepli icon in the reply box on LinkedIn, Twitter/X or Instagram and it produces a ready-to-edit comment based on the conversation in front of you.

The design philosophy is bare-bones and privacy-first. There is no signup and no account: you paste your own OpenAI API key into the extension and it calls the API directly from your browser. The developer's Chrome Web Store disclosure states that data is not sold to third parties and is not used for creditworthiness or unrelated purposes, which is a meaningful contrast to tools that route your social activity through their own servers.

OpenRepli is a niche, early-stage utility rather than a full social media suite. The store listing shows version 0.1.1 (updated April 2024), a footprint of roughly 24 KB, and a very small user base with no ratings yet. That makes it attractive for individuals who want a lightweight reply helper at no extra cost beyond their own API usage, but a poor fit for teams needing scheduling, analytics or multi-seat management. Note that this is an independent third-party extension and is not an official OpenAI product, even though it relies on the OpenAI API.

**Pricing & Plans:** Free. OpenRepli is a free Chrome Web Store extension with no subscription; you supply your own OpenAI API key and pay OpenAI directly for the API usage you generate.

- **One-click reply generation:** Open the extension icon in the comment interface on LinkedIn, Twitter/X or Instagram and it drafts a reply for that specific thread.
- **Bring your own OpenAI key:** Paste your own GPT API key in the extension settings — no account, no proxy server, and no data collection per the developer's disclosure.
- **Customizable instructions:** Write instructions to match your brand voice or personal persona so generated comments sound like you rather than a default chatbot.
- **In-browser, cross-platform:** Runs as a lightweight Chrome extension (about 24 KB) directly in the sites you already use, so there is nothing heavy to install or manage.

**Strengths:** Completely free extension with no subscription tier; No signup or account required; Works inside LinkedIn, Twitter/X and Instagram without leaving the page; Custom instructions adapt replies to your brand or persona

**Limitations:** Very small install base (about 7 users as shown on the store listing) and only version 0.1.1; No ratings yet, so quality signals from other users are essentially absent; Requires your own OpenAI API key and the associated usage costs; Limited to LinkedIn, Twitter/X and Instagram, with no scheduling, analytics or team features
