CometAPI
Unified API for 500+ AI models at 20-40% below official pricing.
CometAPI delivers on its promise: a permanent 20% minimum discount on every model, no monthly fee, and zero lock-in. It's the most cost-efficient aggregator we've seen—OpenRouter adds a surcharge, CometAPI subtracts. Just confirm your must-have models are in the catalog before committing. Recent additions keep it current, but remember it's an intermediary, so upstream availability matters.

Skip CometAPI if you need model fine-tuning, on-premise deployment, or rely on a niche model not in its catalog; you'll find those only with direct providers.
Some models carry lower discounts than the advertised 20%—DeepSeek V4 Pro is discounted only 4%, so check per-model rates before assuming savings.
CometAPI's pay-as-you-go pricing with 20%+ discounts fits startups and scaling teams who want flexibility, while OpenRouter charges a surcharge and direct providers bill separately per vendor. It's cheaper than most alternatives, though enterprise volume pricing is custom.

Best for SaaS developers embedding AI features who want to avoid provider lock-in and cut API costs by 20%+, Enterprise teams centralizing AI spend and governance under one account with per-team budgets, AI automation builders using n8n, Make, or Zapier who need one key for multiple models.

About CometAPI
CometAPI is a unified AI API gateway that gives developers one API key to access 500+ models from providers like OpenAI, Anthropic, Google, ByteDance, and others, all priced at least 20% below official vendor rates. It's OpenAI-compatible, so you just change your base_url to https://api.cometapi.com/v1 and existing code runs unchanged. Coverage spans text, image, video, and audio, including voice and real-time audio models like gpt-audio-1.5 and GPT-Realtime-2.1. Recent additions like GPT-5.6 Sol, DeepSeek V4 Flash Vision, Grok Imagine, Gemini 3.7 Flash, GLM-5.3, and Qwen3.8 2.4T A95B keep the catalog current for coding, reasoning, and multimodal workloads. For teams, CometAPI centralizes billing: one invoice for all providers, pay-as-you-go credits with no monthly fee, and unused credits roll over indefinitely. The real-time dashboard tracks spend, latency, and call volume, with budget alerts. Enterprise tiers add per-team budgets, custom SLAs, volume discounts, and dedicated support. Integrations include Claude Code, Codex, Gemini, Cline, n8n, Zapier, and Dify, plus a built-in playground for benchmarking prompts across models. CometAPI is built for SaaS developers, enterprise teams, and automation builders who want to cut AI spend without rearchitecting. Compared to OpenRouter—which passes through official pricing plus a surcharge—CometAPI subtracts 20% off the top. It's the cost-efficient choice for consolidating AI access, though it doesn't support fine-tuning or on-prem deployment, and coverage isn't exhaustive. What this means for you: if you're already on the OpenAI SDK, migration is a few lines. If you need niche models or full data control, verify coverage first. For most production use, CometAPI delivers cheaper access to leading models with minimal friction.
Behind the Verdict
CometAPI is a pragmatic choice for teams that want to cut AI API costs without changing their code. The core value prop is simple: every model is priced at least 20% below official rates, with no monthly subscription and no minimum spend. This is a direct inversion of OpenRouter's model, which passes through official pricing and adds a surcharge on credit purchases. For teams spending thousands on inference, the savings are immediate and ongoing. What we like: the OpenAI-compatible endpoint means you can switch your base URL and keep your existing SDK calls. The catalog is broad—500+ models including text, image, video, and audio. Recent additions like GPT-5.6 Sol, DeepSeek V4 Flash Vision, Grok Imagine, and Gemini 3.7 Flash show they're keeping pace with the latest releases. The pay-as-you-go model with rolling credits is friendly for variable workloads, and the integrated dashboard gives you cost and latency visibility in one place. What to watch: like any reseller, CometAPI's availability depends on upstream providers. The discount is consistent at 20% for most models, but some (like DeepSeek V4 Pro) are only discounted 4% per the changelog. There's no fine-tuning support, and the free tier is just one-time test credits—not a persistent free tier. If you rely on a niche model, check the catalog first. But for most production AI workloads, CometAPI is a smart way to consolidate access and reduce spend.

Models Under the Hood
as of 2026-08-30
Limitations
- CometAPI is an intermediary, so service depends on upstream providers and their availability.
- The 20% discount applies to official models, but some models have different pricing (e.g., DeepSeek V4 Pro at 4% discount).
- No free tier beyond initial test credits.
- Model deprecations require active migration to avoid service interruption.
