Cheapest AI API: Provider Comparison 2026

AI API pricing depends on three factors: the 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-5.5, Claude Opus 4.8, Gemini 3.1 Pro) operate in their own data centers with huge operational expenses: rent, electricity, cooling, staff. The price per 1M tokens varies from $1.50 (Gemini 3.5 Flash) to $30 (GPT-5.5 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 do not pay for model development. Typical price: $0.20 – $2.00/1M tokens. This is significantly cheaper, but still a centralized infrastructure with high overhead costs.

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. The Gonka network uses Proof of Useful Work — every computation simultaneously processes a real AI request and secures the blockchain. The result: $0.0069/1M tokens — hundreds of times cheaper than OpenAI.

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

Below is the current price table for August 2026. We have 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 per 1M tokens.

The same models, different price. MiniMax M2.7, DeepSeek V4 Flash, and GLM-5.3 Flash are exactly the same models provided by JoinGonka. Through OpenRouter, the same MiniMax M2.7 costs $0.30/1M for input — tens of times more expensive than JoinGonka's input price ($0.0069/1M). The difference is not in the model, but in the infrastructure: OpenRouter buys inference from commercial hosters, JoinGonka takes it directly from a decentralized network.

What the table shows: the price spread is enormous — from $0.0069/1M at the cheapest (JoinGonka Gateway) to $30/1M at the most expensive (GPT-5.5 output). Even among centralized providers, the difference is huge: Gemini 3.7 Flash is several times cheaper than the flagship output of OpenAI and Anthropic.

Note on quality: GPT-5.5 and Claude Opus 4.8 are frontier models with the best benchmarks. MiniMax M2.7, DeepSeek V4 Flash, and GLM-5.3 Flash are strong open-source models that, for many tasks — coding, text analysis, content generation, agentic scenarios — yield results comparable to GPT-5.5 and Claude Sonnet 4.6. For 90% of tasks (chatbots, automation, RAG, summarization), the difference in quality is unnoticeable, while the price difference is thousands of times.

Hidden costs: some providers charge different prices for input and output tokens. At OpenAI, input costs $5.00 and output costs $30.00/1M. At Anthropic: $5.00 input and $25.00 output. At JoinGonka Gateway, both rates are fractions of a cent: input $0.0069/1M, output $0.021/1M. Output is more expensive than input (as with almost all providers), but hundreds of times cheaper than OpenAI and Anthropic.

Usually, comparing AI API prices is hindered by the difference in models: every provider has their own flagship, and "cheaper" often means "weaker". With DeepSeek V4 Flash, this caveat does not apply — in August 2026, it was added to the Gonka network via governance proposal #94, and now the same model is provided both by standard inference platforms (via OpenRouter) and the decentralized network. By September 2026, DeepSeek itself removed V4 Flash 0731 from its API: requests under the old name are now handled by a different model — DeepSeek-V4.1-Flash. The weights are identical (an open MoE model with 284 billion parameters, ~13 billion active, MIT license), the context is 380K tokens, and the API is OpenAI-compatible in both cases. Only the infrastructure differs — and the price.

What this means for your bill. One million input tokens for the same model costs $0.06 on OpenRouter, vs $0.0069 with us. At a volume of 100M tokens per month (a typical load for an agent reading documentation and a codebase), the difference comes out to $6 vs 69 cents (based on September 2026 prices) — for the same quality of answers, because the model is literally the same.

How to switch. No need to change code: same base_url, same key, use deepseek-ai/DeepSeek-V4-Flash-0731 in the model field. For clients like Claude Code and Cline, there is an installer: npx @joingonka/setup --model deepseek (other network models — --model minimax and --model glm). A detailed analysis of the model — specifications, benchmarks, and comparison with other network models — is available in the article DeepSeek V4 Flash on the Gonka network.

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

No data centers: The Gonka Network consists of 584 GPUs (H100, H200, B300, and others) provided by independent hosts around the world. Hosts earn GNK tokens for performing AI computations. There is no data center rent, no corporate overhead, and no brand markup.

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-waste economy: 100% of the computing power goes toward useful work.

0% commission for GNK payments: If you top up your JoinGonka Gateway balance with GNK tokens, the platform commission is 0%. You pay only the base cost of inference in the network. For WGNK deposits from Ethereum, the commission is 1%. When paying with USDT, the commission is 5% — a fee for conversion and convenience.

The same model — ~6—58 times cheaper: Gonka's open models (MiniMax-M2.7, DeepSeek V4 Flash, GLM-5.3 Flash) are available on regular inference platforms as well. On OpenRouter, the same MiniMax-M2.7 costs $0.30 per 1M input tokens and $1.20 output, GLM-5.3 Flash — $0.09/$0.30, and DeepSeek V4 Flash 0731 — from $0.06/$0.12 (DeepSeek itself has already removed this version from its API in favor of V4.1 Flash). JoinGonka Gateway charges ~$0.0069/1M input and ~$0.021/1M output — several to dozens of times cheaper for the exact same model weights. A detailed analysis can be found in the article JoinGonka Gateway: full review.

Two API formats: JoinGonka supports 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:
