## 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

## Resemble AI

Resemble AI began as a voice generation platform and has since concentrated its commercial focus on defending against synthetic media. Its detection stack combines pattern matching with a world-model architecture to spot deviations from physical reality, and the models are trained in-house across audio, image, video and text. Published accuracy figures reach 99.5% for audio, 98.2% for video and 95.8% for images, and results are returned as deterministic scores with human-readable explanations rather than opaque probabilities.

The platform is designed to sit where deepfakes actually appear. It can be deployed into carrier call infrastructure to alert teams before a fraudulent call ends, into meeting platforms to flag synthetic voices and faces, and into KYC or onboarding flows to verify identity. A Chrome extension and native Microsoft Teams integration let individuals run checks directly in the tools they already use, and everything is also reachable through an API and SDKs, with a pip install quickstart.

Alongside detection, Resemble offers provenance tooling: PerTh adds imperceptible multimodal watermarks that support C2PA compliance and EU AI Act obligations, and identity registration lets organisations enrol and authenticate voices and likenesses. Resemble also maintains the original voice cloning and text-to-speech capabilities, a public deepfake incident database and threat research on attack vectors and regulation.

**Pricing & Plans:** Freemium and enterprise: you can start free with an API key for detection and voice services, while production deployments, watermarking, identity registration and integrations are sold through contact-for-pricing enterprise agreements.

- **Multimodal deepfake detection:** Detect AI-generated audio, video and images with published accuracy of 99.5%, 98.2% and 95.8% respectively, via one API.
- **Explainable intelligence layer:** Results return as deterministic scores plus structured, human-readable explanations suitable for audits and incident review.
- **PerTh watermarking and provenance:** Apply imperceptible multimodal watermarks that help meet EU AI Act and C2PA provenance requirements.
- **Identity registration and matching:** Enrol voices and likenesses so organisations can authenticate speakers and detect impersonation attempts.
- **Integrations where deepfakes happen:** Deploy in call centres, meeting platforms, KYC flows and content pipelines, or run checks in a browser extension and Microsoft Teams.

**Strengths:** Detection, watermarking and identity verification in one platform; Strong third-party and internal benchmarks across audio, video and image; Explainable, deterministic results that hold up in audits and investigations; Deployable via API, SDKs, Chrome extension and native Microsoft Teams integration

**Limitations:** The strongest capabilities target enterprise procurement, so pricing requires a sales conversation; Detection accuracy is never absolute, so results should support rather than replace human review; The earlier voice-generation focus can make it harder to tell which products are current at a glance
