## AI/ML API

AI/ML API is a developer-first aggregation layer for generative AI. Instead of signing up with each model vendor separately, you get a single universal endpoint plus an OpenAI-compatible SDK, so existing code that points at OPENAI_API_KEY, ANTHROPIC_API_KEY or GEMINI_API_KEY can be redirected to a single AIML_API_KEY and switch between models without rewriting integrations. The catalogue spans chat and reasoning models, code models, image and video generators, text-to-speech and music models, embeddings, OCR, moderation and image-to-3D pipelines.

Beyond raw models, the platform ships an MCP tool surface with 1,000+ connectors covering web search, YouTube transcripts, X/Twitter scraping, LinkedIn jobs, Reddit research and marketing/SEO data, which lets agent builders combine model reasoning with live external data. A routing layer called Jev Router automatically sends simple tasks to cheap, fast models and reserves frontier models for hard work, with the vendor claiming automatic cost reductions of up to 50%. Usage is metered per token, image, second of video or second of audio, with the company stating no markup over going direct to the provider.

The service targets startups and production engineering teams as well as enterprises. Self-serve accounts top up from a small minimum balance and pay for exactly what they consume, while larger organisations can request custom pricing, dedicated servers, private model deployments and higher rate limits with a dedicated account manager. Privacy documentation states that customer inputs are not used to train or fine-tune models.

**Pricing & Plans:** Pay-as-you-go with credits you can top up from around $20, billed per token, image, video second or audio second with a stated 0% markup over provider list prices. An enterprise tier with custom pricing, dedicated servers, private models and unlimited rate limits is available on request.

- **Unified multi-provider endpoint:** Call chat, code, image, video, audio, music, embedding, OCR and 3D models from 70+ providers through one API key and one SDK.
- **OpenAI-compatible integration:** Point existing OpenAI, Anthropic or Gemini SDK code at AI/ML API and swap models by changing the model string rather than the integration.
- **Jev Router cost optimisation:** An automatic router grades task difficulty and sends easy work to cheap models while escalating hard work to stronger ones.
- **1,000+ MCP agent tools:** Give agents live access to Google search, YouTube transcripts, X/Twitter, Reddit, LinkedIn jobs and SEO/marketing data sources.
- **Single consolidated bill:** Model calls and agent tools are metered from one balance with per-category usage receipts for tokens, images, video and audio.

**Strengths:** Very broad model catalogue behind one credential and one invoice; Drops into existing OpenAI-style code with minimal changes; MCP tool library adds research and data capabilities beyond raw models; Stated zero markup makes price comparison against direct providers straightforward

**Limitations:** You depend on a third party in the request path, so platform incidents affect all providers at once; Cost predictability requires active monitoring of per-token and per-second metering; Some cutting-edge model availability can lag the direct provider release

## 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
