Cheapest AI API: Provider Comparison 2026

The price of an AI API depends on three factors: model (size, quality), infrastructure (data centers vs. decentralized network), and the provider's business model (margin, subscriptions, free tiers).

Centralized providers — OpenAI, Anthropic, Google — maintain high prices. Their models (GPT-5.4, Claude Sonnet 4.5, Gemini 2.5) run in their own data centers with huge operational costs: rent, electricity, cooling, staff. The price per 1M tokens varies from $0.15 (Gemini Flash) to $15 (Claude Sonnet 4.5 output). These costs are passed on to users.

Open-source hosting providers — Together AI, Groq, Fireworks — offer open models (DeepSeek, Llama, Qwen) cheaper because they don't pay for model development. Typical price: $0.20 - $2.00/1M tokens. This is significantly cheaper, but still a centralized infrastructure with high overheads.

Decentralized networks — Gonka, Akash, io.net — operate fundamentally differently. Computing power is provided by independent hosts (miners) who receive tokens for their work. No data centers, no corporate expenses, no brand margin. The Gonka network uses Proof of Useful Work — each computation simultaneously processes a real AI inference request and secures the blockchain. The result: $0.001/1M tokens — 2500 times cheaper than OpenAI.

For developers and companies, this means a fundamentally different economy. A project that spent $10,000/month on OpenAI API can get the same volume of inference for $4. Automation, chatbots, RAG pipelines, AI assistants — all this becomes accessible even for small teams without an AI budget.

Below is the current price table for April 2026. We included all major AI API providers: from the largest (OpenAI, Anthropic, Google) to open-source hosters (Together AI, Groq) and decentralized solutions (JoinGonka Gateway). Prices are for 1M tokens.

What is visible from the table: a 15,000x price difference between the cheapest (JoinGonka Gateway, $0.001/1M) and the most expensive (Claude Sonnet 4.5 output, $15/1M). Even among centralized providers, the difference is huge: Gemini Flash is 25 times cheaper than Claude output.

Note on quality: GPT-5.4 and Claude Sonnet 4.5 are frontier models with the best benchmarks. Qwen3-235B is an open-source model with 235 billion parameters that shows performance comparable to GPT-4o on many tasks: coding, text analysis, content generation, multilingualism. For 90% of tasks (chatbots, automation, RAG, summarization), the difference in quality is imperceptible, while the price difference is thousands of times.

Hidden costs: some providers charge different prices for input and output tokens. For OpenAI, input costs $2.50, and output — $10.00/1M. For Anthropic: $3.00 input and $15.00 output. With JoinGonka Gateway, the price is uniform: $0.001/1M for all tokens, with no hidden markups.

JoinGonka Gateway is not just another hosting for AI models. It's a gateway to the decentralized Gonka network, and the network's architecture explains the record low prices.

No data centers: The Gonka Network features over 4,000 GPUs (H100, H200, A100, RTX 4090) provided by independent hosts worldwide. Hosts earn GNK tokens for performing AI computations. There are no data center rents, no corporate expenses, no brand margin.

Proof of Useful Work: Unlike Bitcoin (where mining wastes energy), every computation in Gonka is a real AI inference. Miners receive GNK for processing your requests. This is a zero-loss economy: 100% of computing power goes to useful work.

0% commission when paying with GNK: If you top up your JoinGonka Gateway balance with GNK tokens, the platform commission is 0%. You only pay the base cost of inference in the network. When paying with USDT, the commission is 5% — a fee for conversion and convenience.

Comparison with other Gonka gateways: JoinGonka is not the only gateway to Gonka, but it's the most functional. GonkaGate is 31% more expensive, accepts only GNK, has no Dashboard, and no Anthropic API. Mingles is 400% more expensive. proxy.gonka.gg is 133% more expensive. A detailed comparison is available in the article JoinGonka Gateway: full overview.

Two API formats: JoinGonka is the only Gonka gateway to support both OpenAI (/v1/chat/completions) and Anthropic (/v1/messages) formats. This means that any tool — Cursor, Claude Code, LangChain, n8n — works without modifications.

Connecting to the cheapest AI API takes 2 minutes:

1. Registration: Open gate.joingonka.ai and create an account. Email + password — standard form, no cryptocurrency or wallets needed.
2. Free tokens: Upon registration, you receive 10,000,000 free tokens. This is enough for thousands of requests — sufficient to test the API in your project.
3. Create API key: In the Dashboard, go to API Keys → Create Key. The key starts with jg-. It is displayed once — save it.
4. Connection: Replace base_url in your application with https://gate.joingonka.ai/v1. For Anthropic format: ANTHROPIC_BASE_URL=https://gate.joingonka.ai.

Connection examples for popular tools:

• Cursor — provider change in settings in 30 seconds
• Claude Code — two environment variables: ANTHROPIC_BASE_URL and ANTHROPIC_API_KEY
• Continue.dev — config in config.json
• LangChain — replace base_url in ChatOpenAI()
• n8n — Custom Base URL in credentials

Detailed instructions with code examples (curl, Python, TypeScript) are available in the API Quick Start.

Dashboard: After registration, you get a full control panel — balance, request history, daily consumption, API keys, referral link. Everything is transparent and under control.
