## 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

## Retune

Retune lets a small business or solo founder stand up an AI assistant without hiring an engineer. You point it at the content that already explains your offer — web pages, uploaded documents, a spreadsheet of prices — and the platform turns that material into a bot that can answer visitor questions in your voice. The assistant is then published as a chat widget that sits on your site, with lead capture and hand-off options built in.

Beyond answering questions, Retune has historically been used to package an assistant as a product: creators build a bot around a niche, brand it, and monetise access. Configuration happens through a visual dashboard, so prompts, welcome messages, conversation starters and knowledge sources are all edited in the browser rather than in code.

The most important thing to know in 2025 is the product's status. Retune is in maintenance mode, and the site now explains that the original feature roadmap stalled. Rather than abandon users, the team is building long-requested capabilities — appointment booking, sitemap crawling, voice input, widget theming, webhook delivery, GDPR controls — as separate standalone copies of the platform, offered free to anyone who emails for access. Existing Retune accounts continue to work; the new work simply is not rolled into them automatically. Treat Retune as a capable but no-longer-actively-developed assistant builder, and weigh that against alternatives with active release schedules.

**Pricing & Plans:** Retune has historically used a freemium model with a free tier and paid plans plus a free trial. The current site states that the new agent-built feature copies are free if you run your own copy and are obtained by emailing the team; check the site for current terms.

- **No-code assistant builder:** Configure prompts, welcome messages, conversation starters and persona in a visual dashboard instead of writing code.
- **Train on your own content:** Ground answers in your website pages, uploaded documents or spreadsheets so the bot speaks to your actual offer.
- **Embeddable chat widget:** Publish the assistant as a chat widget visitors can use directly on your site without leaving the page.
- **Lead capture and follow-up:** Collect visitor details during conversation so sales conversations can continue after the chat ends.
- **Agent-built add-on capabilities:** Newer, separately distributed builds add appointment booking, sitemap crawling, voice messages, widget theming and webhook delivery.

**Strengths:** Genuinely no-code — configuration lives in a browser dashboard; Knowledge can come from pages, documents or spreadsheets, not just a FAQ list; Embeddable widget makes deployment on an existing site straightforward; Long-requested features such as booking, voice and webhooks exist in free agent-built copies

**Limitations:** The product is in maintenance mode, so the main app is not receiving new features; New capabilities live in separate copies rather than your existing account; Access to the new builds requires emailing the team rather than a self-serve signup
