## 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

## Speko

The core idea is that no single speech model wins everywhere. Speko's benchmark shows six different models taking the top spot across 18 languages, and notes that a large share of models are only ever measured in English, leaving their ranking in other languages unknown. Instead of committing to one vendor, Speko routes each stage of a voice pipeline — STT, LLM and TTS — to whichever model performs best for the language your users actually speak, with measured selection and failover before the response starts.

Two commercial shapes are offered. On Speko infrastructure you pay a single bundled rate of $0.09 per minute covering all three legs. Alternatively, managed routing adds 5% on top of a provider's published rate and lets you use your own provider keys, in which case the provider bills you directly. The router is hosted at router.speko.dev with typed contracts and public OpenAPI and AsyncAPI documentation.

The platform layer targets teams that need working phone agents, not just model access. You can map a call step by step, connect calendars, CRMs, your own APIs and documentation into any step, buy a phone number, test drafts against simulated callers including adversarial ones, and score every live call against checks you write in plain language. Native integrations exist for LiveKit and Pipecat, and an MCP server exposes Speko to Claude, ChatGPT, Grok, Cursor and Claude Code. Speko states it is backed by Y Combinator and that new accounts receive $10 in credit.

**Pricing & Plans:** Two models. On Speko infrastructure, a flat $0.09 per minute bundles STT, LLM and TTS; calls bill from answer to hang-up and unanswered calls cost nothing. With managed routing, you pay the selected provider's published rate plus 5%. $10 in signup credit applies to every account. Phone numbers cost $1 setup and $2 per month for most numbers, and calls on Speko numbers add the carrier charge plus 20%.

- **Language-aware model routing:** STT, LLM and TTS are selected per language based on an independent benchmark covering 89 models across 18 languages, with pre-response failover.
- **Voice agent platform:** Design a call step by step, plug calendars, CRMs, your APIs and docs into any step, then run it with inbound, outbound and call-list support.
- **Simulated caller testing:** Draft agents are tested against simulated callers, including red-team scenarios that try to break the flow, before they go live.
- **Plain-language call scoring:** Every live call is scored against checks you write in everyday language, for example reading back a date or never quoting a price.
- **Framework and MCP integrations:** Native Gateway services for LiveKit and Pipecat, plus an MCP server for Claude, ChatGPT, Grok, Cursor and Claude Code.

**Strengths:** Independent, language-by-language benchmark rather than a single accuracy claim; Provider-neutral routing with the option to bring your own keys; Clear, simple pricing: $0.09 per minute bundled or 5% on routed provider spend; Agent platform includes phone numbers, evaluation and live call monitoring

**Limitations:** Public preview with no SLA and email-only support outside enterprise; The benchmark and model catalogue move quickly, so routing decisions need periodic review; Telephony costs sit on top of the per-minute rate, and international routes can exceed the US minimum
