† OR costs equal the selected endpoint's listed rate × 1.055. The 5.5% fee is charged when buying credits, not again on each request.
* Savings use a 3:1 input-to-output token ratio with no caching. Cache-read prices are listed separately and are excluded from this percentage.
¹ GPT-6.1 Sol, GPT-6.1 Terra and GPT-5.5 use the base tier below 272K input tokens per request. ² GLM 5.1 and GLM 5 Turbo use the base tier below 32K context tokens per request. ³ Qwen3.7 Plus uses the base tier below 256K input tokens per request.

FAQ
Can I use ModelGo as an OpenRouter alternative?
ModelGo provides access to multiple models through one account. Supported SDKs and coding tools can connect using the appropriate ModelGo API address, API key and model name. Check the model documentation for protocol and feature compatibility.
Do I need a separate account with each model provider?
No. Create a ModelGo account and use a ModelGo API key to call platform models. ModelGo manages upstream access, so you do not need accounts with individual model providers. You cannot connect your own provider accounts or API keys.
Is ModelGo cheaper than OpenRouter?
Whether ModelGo costs less than OpenRouter depends on the model, selected provider and token mix. Under the table’s stated assumptions, GLM 5.3 costs 49.43% less and GPT-6.1 Sol costs 24.64% less. ModelGo charges no additional platform service fee.
Do these prices include OpenRouter’s platform fee?
Yes. The OR columns use the selected Standard endpoint’s listed rates × 1.055, including the 5.5% fee charged when buying credits. The fee is not charged again on each request. Provider prices and promotions vary.
How is the savings percentage calculated?
Every model uses the same comparison volume: 3 million regular input tokens and 1 million output tokens, with no caching.
Savings = [1 − (3 × MG input + MG output) ÷ (3 × OR input incl. fee + OR output incl. fee)] × 100%
For GLM 5.3, ModelGo costs 3 × $0.7059 + $2.4706 = $4.5883. The selected OR endpoint costs 3 × $1.477 + $4.642 = $9.073, including the allocated fee. The difference is 49.43%.
How does prompt caching affect costs?
Repeated system prompts, tool definitions and long documents can be billed at cache-read rates when they meet the model's caching requirements. For coding agents, multi-turn chat and knowledge-base applications, check regular input rates, cache-read rates and any cache-write charges together.
As more input is read from cache, regular input rates usually have less influence on the total bill. For example, ModelGo's GLM 5.1 cache-read rate is higher than that of the selected OR endpoint, so the 45.07% uncached savings figure does not apply to a cache-heavy workload. Cache writes, retention periods and setup requirements also affect the final cost.
Can I keep using my existing SDK or coding tool?
Supported SDKs and tools can connect to ModelGo. Compatible API integrations usually involve changing the API address, API key and model name. Models can use different protocols, paths and parameters, so follow the documentation for the model you choose.
See the integration guide and coding tool setup.
How do I get started, and what credits are available?
Sign up for ModelGo to receive $0.50 in credits, then earn another $2 by completing new-user tasks. Top-ups also come with bonus credits. Signup, task and top-up bonuses add up to a maximum of $12.50.
Use the credits to try models on the platform, with charges based on actual usage. Choose a model from the model catalog, then follow the integration guide to configure your API key and start making requests.
