## 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

## Subex

Subex is a long-established telecom software vendor that has repositioned itself around an AI-first approach. The site describes the company as an AI-native provider helping operators move from reactive processes to predictive and autonomous assurance, and it leans heavily on a theme of "fearless, seamless, fraud-free" operations. The core promise is simple: detect revenue leakage, fraud and partner exceptions early, explain why they happened, and either fix them automatically or escalate a clear recommendation to a specialist.

The product surface is broad and telecom-specific. FraudZap covers the major fraud families operators face today — bypass, SMS, handset, mobile money, MVNO, subscription and roaming fraud, CLI spoofing, robocalling and artificially inflated traffic. The assurance portfolio handles revenue, margin, cost, migration and regulatory assurance, plus adjacent areas such as order management, collections, financial reporting and CX assurance. A third pillar handles ecosystem management: partner lifecycle, digital services and IoT/M2M billing, wholesale and interconnect billing, settlement, dispute management, route optimisation and roaming. AI Agent Squads and dedicated agents (fraud investigative, PEM, business assurance) sit across these workflows.

Subex emphasises scale and longevity: over 30 years of innovation, customers in more than 110 countries, 200 billion-plus CDRs processed in a single instance, and roughly 60 percent of customers staying more than eight years. Pricing is not published and the company sells through demos, which is typical for enterprise telecom software. Deployment is designed to sit alongside existing platforms rather than replace them, with agents operating inside configured guardrails and keeping specialists in control of consequential decisions.

**Pricing & Plans:** Contact for Pricing. Subex does not publish rates or self-serve plans; pricing is quoted per engagement after a demo request, based on the modules selected and the scale of the operator's network and subscriber base.

- **FraudZap fraud management:** FraudZap covers bypass fraud, SMS fraud, handset and mobile money fraud, subscription and roaming fraud, CLI spoofing, robocalling and artificially inflated traffic.
- **Business assurance suite:** Revenue, margin, cost, migration and regulatory assurance identify leakage and service or experience risks before they reach customers.
- **Agentic AI squads:** AI Agent Squads reason across evidence, execute configured checks, package supporting evidence and recommend actions with human oversight and audit trails.
- **Partner ecosystem management:** Replace email-and-spreadsheet partner operations with digital onboarding, offer design, order flows, settlements and reconciliation across B2B2X chains.
- **Billing and settlement:** Billing and settlement for wholesale, interconnect, roaming, IoT/M2M, digital services, content and enterprise, plus telecom-specific collections and payments.
- **Managed and advisory services:** Business consulting and managed services to run assurance, fraud and partner operations on the customer's behalf.

**Strengths:** Deep telecom domain coverage from fraud to billing to partner management; Agentic AI investigates cases and provides audit trails rather than only summarising; Human-in-the-loop design keeps specialists approving consequential actions; Long track record with operators in more than 110 countries

**Limitations:** Enterprise pricing is not published; buyers must go through a demo and sales cycle; The platform is highly specialised for telecom operators, so it is not relevant to general businesses; Overlapping product names (multiple FraudZap and assurance modules) can be confusing when scoping a deployment; Full value depends on integrating with existing BSS, OSS and billing systems, which is a sizeable implementation effort
