## 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

## SleekFlow

SleekFlow positions itself as an AI suite for revenue-driving conversations. Rather than treating customer messaging as a support cost centre, the platform is built around the idea that every chat, email, and call is a potential sale that should not be lost to a slow reply. It is used by more than 7,000 businesses across 70 countries according to the company's own figures.

The core of the product is an omnichannel inbox that consolidates WhatsApp, Instagram, TikTok, email, and voice into a single workspace. Each conversation is tied to a CRM profile showing lifecycle stage, purchase history, and owner assignment, so agents open a thread already knowing who they are talking to. On top of that sits AgentFlow, an AI agent layer that the company describes as an AI go-to-market workforce rather than a generic chatbot.

AgentFlow is trained on your website and internal data, then connected to systems such as Shopify, CRMs, and internal tools without code so it can recommend products, schedule bookings, and resolve tickets using live information. SleekFlow is also an official WhatsApp Business Solution Provider, and the platform extends into campaigns, catalogs and payment links, ticketing, analytics, and conversation-mining CX intelligence. Industry-specific solutions are offered for education, e-commerce, travel, real estate, automotive, beauty and wellness, and retail.

**Pricing & Plans:** SleekFlow is sold on a paid, quote-based model with a free trial and a book-a-demo path. Public pricing is presented through a WhatsApp pricing calculator and a contact-sales motion, so exact costs depend on channel volume, seats, and the modules you deploy.

- **Omnichannel team inbox:** Pull conversations from WhatsApp, Instagram, TikTok, email, and calls into one inbox where each thread links to a CRM profile with lifecycle stage and purchase history.
- **AgentFlow AI agents:** An AI workforce that follows your playbook to qualify leads, recommend products, schedule appointments, and route hot prospects to humans around the clock.
- **Flow builder and campaigns:** Build messaging automations and journeys visually, then send personalized broadcasts for restock reminders, loyalty offers, and birthdays.
- **CX intelligence:** Mine customer conversations for insight into what drives purchases and how your team performs, so CX decisions rest on real data rather than guesswork.
- **Social CRM and ticketing:** Store customer records, track pre-sales inquiries with ticketing, and sell directly in chats using catalogs and payment links.

**Strengths:** Consolidates WhatsApp, Instagram, TikTok, email, and calls into one inbox with CRM context attached; Official WhatsApp Business Solution Provider status adds credibility to the core messaging channel; AI agents connect to Shopify, CRMs, and internal systems without code and act on real-time data; Conversation-mining CX intelligence turns support and sales chats into structured business insight

**Limitations:** Quote-based pricing means you must talk to sales before knowing real costs; The breadth of modules — inbox, AI agents, CRM, ticketing, campaigns — may be more than a small team needs; Full value depends on connecting external systems and channels, which takes setup effort
