## Agentkit

Agentkit is aimed at the recurring problem of a support queue that fills with the same dozen questions. Instead of staffing around the clock, you give Agentkit your existing knowledge — website pages, PDFs, Word documents, pasted text, or hand-written Q&A pairs — and it turns that material into a conversational agent that can answer visitors at any hour. A typical ten-to-fifty page site is indexed in a few minutes, and web sources can be refreshed on a schedule so answers do not go stale.

Once trained, the agent is published with one script tag that works on WordPress, Shopify, Webflow, Wix, Squarespace, Framer, Next.js, or any HTML page, and it can also be connected to Instagram DMs, WhatsApp, and email. You decide which model powers each chatbot from a menu that spans OpenAI GPT, Anthropic Claude, and Google Gemini families, and you can change that choice per agent at any time.

The platform extends beyond answering questions. Agents can trigger buttons, forms, and API calls in context, capture leads mid-conversation, and respond in more than 95 languages with automatic language detection. A conversation inbox lets you review what visitors actually asked, spot gaps in your knowledge base, monitor credit usage, and export collected leads.

The free tier covers experimentation with a monthly credit allowance and a single chatbot; paid tiers add larger credit pools, more chatbots, team seats, auto-retrain, branding removal, integrations, and API access.

**Pricing & Plans:** Freemium. A free plan includes a monthly credit allowance, one chatbot, 10 website links, and basic actions with no credit card required. Hobby costs $29.99/month, Standard $119.99/month, and Pro $399.99/month when billed monthly, with annual billing available; higher tiers add credits, chatbots, team seats, integrations, and API access.

- **Multi-source training:** Crawl any URL and index pages automatically, upload PDFs and Word documents, paste text, or lock in exact Q&A answers for the questions visitors ask most.
- **Selectable AI models:** Choose from OpenAI GPT, Anthropic Claude, and Google Gemini models, and switch the model per chatbot at any time without rebuilding it.
- **Brand customization:** Match brand colors, welcome message, chat bubble styling, and suggested prompts so the widget feels native to your site.
- **Guardrails and controls:** Set domain restrictions, rate limiting, and visibility controls so your agent behaves within the boundaries you define.
- **Lead capture and inbox:** Collect emails and contact details inside the conversation, read full chat logs in an inbox, and export every captured lead.

**Strengths:** Trains on websites, documents, and exact Q&A pairs, so you can mix broad and precise knowledge; One script tag embeds on WordPress, Shopify, Webflow, Wix, and any HTML site; Choose between OpenAI, Anthropic, and Google models per chatbot and switch later; Built-in lead capture, conversation inbox, and lead export in the same product

## 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
