## Checkstep

Checkstep is built for the teams responsible for keeping user-generated and professional content safe: trust and safety, content operations and compliance leaders at gaming, marketplace, streaming, dating, social and review platforms. Rather than a single classifier, it provides an integrated platform where policy is defined once and then enforced consistently across every content type and language.

At its core is a configurable policy engine covering the major abuse categories. You set what is and is not allowed on your platform, and Checkstep's workflow and automation layer applies those rules. An AI marketplace gives access to leading moderation models so teams can determine which fits their policy and content needs, test alternatives and swap models without re-engineering the whole pipeline. Moderation itself blends automated scanning from ModBot with human review, letting specialists focus on the highest-risk or most nuanced cases.

Compliance is a first-class feature: the platform centralises the data required under the EU Digital Services Act and can generate transparency reports for European users on demand. Checkstep reports a 90% reduction in human moderation costs, 78% faster moderation and 98% detection accuracy, and works with handpicked BPO and technology partners for customers who need extra capacity. Public case studies include Trustpilot, JustGiving, Star Stable and 123 Multimedia.

**Pricing & Plans:** Free trial available; full pricing is provided on request after a demo, with costs depending on content volume and deployment scope.

- **Multi-format moderation:** Scan and moderate text, images, video and audio in more than 100 languages from one integrated platform.
- **Configurable policy engine:** Define your own rules across all major abuse categories, then let the workflow and automation layer enforce them consistently.
- **AI model marketplace:** Access leading moderation models, test which fit your policy, and swap providers seamlessly without rebuilding pipelines.
- **Human-in-the-loop workflows:** Blend automated ModBot screening with expert review so your team focuses on the cases that matter most.
- **DSA transparency reporting:** Centrally manage regulatory data and generate transparency reports for your European users instantly.

**Strengths:** One platform covers text, image, video and audio in over 100 languages; Policy engine plus model marketplace lets you tailor and swap AI models without rework; DSA transparency reporting is built in, easing regulatory compliance; Documented case studies with named customers and published efficiency figures

**Limitations:** Pricing is not published, so you need a demo and quote before budgeting; Enterprise-oriented setup means it is not aimed at small communities or solo developers; Effective deployment still requires staff to define policy and manage human review queues

## 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
