## 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

## TestDriver

TestDriver is an AI QA engineer for pull requests. Instead of reviewing code diffs in isolation, it spins up a real desktop sandbox, runs your application, and tests it the way a real user would—clicking, typing and reading the screen. Its vision agent reads the PR diff to understand what changed, generates end-to-end tests from that context, and verifies that the new behavior actually works before it merges.

Because testing is driven by AI vision rather than selectors, TestDriver works on surfaces that break traditional automation: third-party web apps you don't own, Chrome extensions with popups and background pages, native Windows and macOS applications, VS Code extensions, canvas, video players, iFrames and OAuth flows. When the UI shifts and a cached element no longer matches, the agent re-invokes the AI to relocate it, updates the cache and keeps going—so tests self-heal instead of failing on every pixel change.

Generated tests are plain Vitest, so they run identically on your machine and in CI across web, desktop and extensions on real VMs. The agent can also contribute tests back as a new pull request with the code committed for your review. For debugging, TestDriver offers video replays of failing runs, full network inspection with headers and payloads, CPU and memory monitoring, and a step-by-step action log. Pro Cloud pricing starts at $24 per seat per month with 360 testing minutes included, and a free trial is available without a credit card.

**Pricing & Plans:** Free trial (no credit card required) and paid plans. Pro Cloud starts at $24 per seat per month with 360 testing minutes included; enterprise options are available on request.

- **AI code review on every pull request:** TestDriver reviews every pull request automatically, reads the diff with its vision agent, and generates end-to-end tests straight from the PR content to prove the new behavior works.
- **Runs your app in a real desktop sandbox:** Tests run your actual application in a real desktop sandbox—clicking, typing and reading the screen—so they catch runtime and visual bugs, not just code diffs.
- **Self-healing tests:** When the UI shifts and a cached element no longer matches, the AI finds it again, updates the cache and continues, so tests survive redesigns without rewrites.
- **Contributes tests back as a pull request:** Once a test passes, TestDriver opens a fresh pull request with the generated Vitest test code committed, so coverage lands in your repo alongside the change it protects.
- **Debugging and quality monitoring:** Jump from a red build to a video replay of the run, inspect every network request, monitor CPU and memory, and track pass rates, flaky tests and failure trends.

**Strengths:** Runs the real app in a desktop sandbox and catches genuine runtime and visual bugs; No selectors or DOM dependency—tests survive UI changes via self-healing; Covers web, desktop, mobile-style and third-party apps that break other tools; Generates tests and opens pull requests automatically, saving QA hours

**Limitations:** Pricing scales with seats and testing minutes; Focused on GitHub-centric workflows; Running a full desktop sandbox per PR consumes CI time and resources; Advanced enterprise needs may require contacting sales
