## Modelflare

Modelflare's core idea is consolidation. Rather than managing separate accounts, API keys, and invoices for OpenAI, Anthropic, Google, and a growing list of image and video providers, you hold one balance and one key. Requests can be sent with OpenAI SDKs against https://modelflare.dev/v1, or with Anthropic and Gemini SDKs against the bare host, and each model is listed alongside the official rate for its billing unit — tokens, images, or seconds of video.

Reliability is handled at the routing layer. Each model can be served by several routing groups, and where upstream failures allow failover you can configure a primary route plus ordered backups, so a single API key keeps requests flowing even when one provider wobbles. Every request records its token usage and cost, while per-project keys can carry quotas, expiry dates, and model or IP restrictions.

For teams, enterprise accounts add a shared balance with a dedicated console: admins invite members by email, give each an unlimited, one-time, or monthly budget, issue keys prefixed with the company name, top up balances, and review usage, creations, and admin actions. Alerts warn before a balance or member budget runs out, and the service is stated as available in 171 countries and territories. Modelflare also offers an engineering blog, integrations for VS Code, MCP, and n8n, an affiliate program, and Castaly, a no-code studio for image and video generation that shares the same account balance.

**Pricing & Plans:** Modelflare is paid and usage-based. You start with pay-as-you-go credits or choose a subscription plan with an included quota, and each model shows its rate next to the official one in units such as tokens, images, or video seconds. Top-up and refund policies are published, and enterprise accounts add member budgets with prepaid top-ups.

- **One OpenAI-compatible endpoint:** Use a single API key and base URL with OpenAI SDKs and compatible tools, or the bare host with Anthropic and Gemini SDKs, to reach text, image, video, and audio models from many providers.
- **Provider routing with ordered fallback:** Configure a primary route plus ordered backups for a regular API key so requests can fail over to another eligible route when an upstream provider has trouble.
- **Per-request usage and cost tracking:** Every request logs its token usage and cost in the console, with model prices listed beside the official rate for each routing group and billing unit.
- **Enterprise team console:** Invite admins and members by email, assign unlimited, one-time, or monthly budgets, issue keys prefixed with your company name, top up, and audit every action.
- **Castaly creative studio:** Sign in with the same account to pick an image or video model in a no-code studio, describe your idea, and share balance and usage records with the API side.

**Strengths:** One key and one balance across many model providers reduces integration and billing overhead; Routing with ordered fallback keeps requests moving when an upstream provider fails; Granular cost visibility down to the individual request, member, model, and key; No-code Castaly studio shares the same account, so creative users and developers bill together

**Limitations:** Prices vary by model and routing group, so cost forecasting still requires checking each rate; Reseller-style pricing means availability and terms can depend on upstream providers

## ZeroGPT

ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation.

Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%.

Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app.

**Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations.

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
- **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
- **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
- **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale.

**Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper

**Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
