## 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

## Perplexity

Perplexity is an AI-native answer engine and autonomous research platform designed to replace traditional keyword search and fragmented browser tab workflows. Instead of returning a ranked list of blue links, Perplexity interprets complex natural-language queries, crawls live web indexes, academic databases, financial filings, and social discussions in real time, and synthesizes direct, structured answers anchored by numbered inline citations. Beyond conversational search, the platform has evolved into a broader agentic ecosystem encompassing Perplexity Computer for autonomous multi-step tasks and the Comet AI browser assistant.

Under the hood, Perplexity orchestrates its proprietary web-grounded Sonar model family alongside frontier third-party reasoning models—allowing paid subscribers to route queries through Claude Opus 4 and Sonnet 4, OpenAI's o3-pro and GPT series, or Google's Gemini models, or run parallel evaluations via Model Council. Its Deep Research mode autonomously decomposes intricate questions, conducts dozens of iterative searches across hundreds of primary sources, and compiles exhaustive, exportable briefing reports in minutes. Users can also organize ongoing projects inside Perplexity Spaces, which fuse uploaded private documents (PDFs, CSVs, docs) with live web grounding and custom system instructions.

Perplexity serves an expansive audience ranging from students and journalists to equity analysts, legal researchers, and software engineers. Individual users can rely on the free tier for everyday fact-checking, step up to Perplexity Pro ($20/month) for daily deep research and model switching, or subscribe to Perplexity Max ($200/month) for uncapped high-compute agentic runs. Organizations adopt Enterprise Pro ($40/seat/month) and Enterprise Max ($325/seat/month) for SOC 2 compliance, zero data training guarantees, and internal knowledge connectors, while developers integrate real-time grounded citations into custom software via the Sonar REST API.

**Pricing & Plans:** Offers a permanent Free tier with unlimited Quick Searches, 3 Pro Searches per day, and 1 Deep Research query per month; Perplexity Pro costs $20/month ($200/year) and Perplexity Max costs $200/month ($2,000/year) for individuals. Team plans start at $40/seat/month ($400/seat/year) for Enterprise Pro and $325/seat/month for Enterprise Max, alongside usage-based Sonar API billing.

- **Deep Research Autonomous Reports:** Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
- **Multi-Model Routing & Model Council:** Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
- **Perplexity Spaces & Hybrid RAG:** Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
- **Perplexity Computer & Comet Assistant:** Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
- **Sonar Web-Grounded Developer API:** Exposes Sonar, Sonar Pro, Sonar Reasoning Pro, and Sonar Deep Research over standard HTTP endpoints so developers can embed low-latency, live-cited web intelligence directly into third-party applications.

**Strengths:** Every generated statement links directly to numbered, verifiable web or document sources, drastically reducing ungrounded LLM hallucinations.; Deep Research mode delivers comprehensive, multi-page synthesis reports at a fraction of the time required for manual desk research.; Broad model optionality lets subscribers use Sonar, Claude, OpenAI, and Gemini models under a single $20/month subscription.; Focused search scopes (Academic, Finance, Web, Social) and Spaces allow clean separation between general browsing and domain-specific knowledge work.

**Limitations:** The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.; Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.; Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.
