OpenRouter — A broad model catalog and provider choice

OpenRouter makes sense if your shortlist changes frequently or you need to compare providers serving the same model. Its catalog includes proprietary and open-weight models, and free variants can help you test an integration before you fund it. Provider preferences also give experienced teams a way to balance availability, latency, data handling, and cost without wiring up several provider SDKs.

The main trade-off is that the token quote alone may understate what you pay. OpenRouter lists a platform fee on credit purchases, with different terms by plan. Free variants also have their own request limits and availability. If your application depends on one particular model, compare that route at a realistic monthly volume instead of using the cheapest model in the catalog as a stand-in.

Keep OpenRouter if a long list of models or the ability to choose among multiple hosts is worth more to you than a discount on one route. Before moving, write down which provider restrictions and fallback settings your application relies on. Those choices may need to be re-created in another gateway.

LAYSO — Lower prices on selected routes with one managed API key

LAYSO fits developers who regularly call a handful of models and want to pay less on those routes without running a proxy. The public catalog listed 219 model entries at the time of comparison. One key can access eligible GPT, Claude, and Gemini models, and the catalog exposes input, output, and cache prices by route. The ordinary API bills by usage against prepaid platform credits. Checkout can offer card, Alipay, WeChat Pay, UPI and crypto. Method availability and minimums depend on the checkout option and location.

The 50% figure in this guide applies to the quoted GPT-5.4 mini route. Other models, routes, and accounts can have different prices. Verify that the route and exact model ID are available to your key. A public catalog listing shows what the platform offers, while your key’s model list shows what you can call.

OpenRouter offers more catalog entries in this snapshot. If you depend on a niche model or a specific upstream provider, confirm availability before switching. LAYSO is a closer fit if your workloads are predictable enough to price individually. Its free model activities use a key bound to the featured model. For example, the November 2026 GPT-6.1 Sol event published a 10-billion-token shared pool and a per-account cap of 1,000 successful requests daily. Eligibility and remaining capacity appear on the activity page.

LiteLLM — A self-hosted, open-source gateway

LiteLLM is the strongest alternative here when you want to operate the gateway in your own environment. The proxy offers an OpenAI-compatible endpoint and integrates with more than 100 providers. That number describes integrations rather than a catalog of models you can call immediately. You decide which models to expose, which upstream credentials to use, and how requests travel through your infrastructure.

The open-source proxy is free to run. Budget separately for provider inference, compute, storage, and whoever will maintain the service. A production deployment needs key rotation, monitoring, upgrades, and a plan for when a provider starts returning errors or throttles your traffic. You also need to decide how to meter internal projects and reconcile usage against provider invoices.

Choose LiteLLM when deployment control is a requirement and your team already operates internal services. It can be a better fit than a hosted catalog for private routing or internal provider keys. A managed gateway is usually easier to evaluate if your immediate goal is a working API key and a predictable quote for one model.

Requesty — Managed routing with a bounded free trial for real requests

Requesty is a practical option for developers who want a managed router and a free allowance they can try with their own application. Its public pricing lists up to 200 daily requests on the free tier, subject to the available free models. Its catalog reports 244 unique models and lists a larger number of provider endpoints. Compare unique models when breadth matters, and compare endpoints when you care about alternate routes.

Its published pay-as-you-go pricing adds 5% to provider rates. Requesty also documents a bring-your-own-key option without that markup, in which the upstream provider charges for inference. Check which arrangement applies before comparing the figures on the model directory to the amount you expect to pay.

Requesty is useful when you want to test routing and monitoring together with minimal setup. It may be less attractive for a workload that sends the same expensive model request at high volume every day. Take one known workload, estimate the cost including markup, and check whether the free allowance covers the tests you actually want to run.

Vercel AI Gateway — A managed gateway for teams already using Vercel or the AI SDK

Vercel AI Gateway is a strong default for teams already shipping applications with the Vercel AI SDK. It offers a large managed catalog, supports the OpenAI-compatible endpoints, and prices tokens at provider list rates with zero gateway markup. The free tier includes a monthly five-dollar credit. Vercel says the monthly free credit no longer applies once the account transitions to paid usage.

Zero markup is useful as a price baseline. It does not make every model or route cheaper than a gateway offering a discount. Check the list price for the exact model, whether payment processing charges apply, and what happens when a request falls back to another credential or provider. Decide which routes you are willing to pay for before allowing fallback on production traffic.

Vercel can be the better fit when your deployment, telemetry, and SDK are already integrated with it. If you use the OpenAI SDK outside Vercel, still test the endpoints and features you depend on. Run one streamed request and one tool call with your actual configuration to check the output and usage fields you rely on.

When a different kind of gateway makes sense

If your search for an OpenRouter alternative starts with a specific infrastructure requirement, look at Portkey for team-wide policies, observability and budgets across providers you already use, Together AI for hosting open-weight models with serverless and dedicated capacity, or GroqCloud for latency-sensitive workloads where a supported model meets your quality requirements.

For a managed API with prepaid credits, start with the LAYSO model catalog and compare the GPT‑5.4 mini route prices for your expected traffic.

OpenRouter pricing and credit fees

OpenRouter’s public pricing separates model usage from the cost of buying credits. On its Standard plan, the platform lists a 5.5% credit purchase fee. The Business plan lists 8%, while Enterprise terms can vary. The per-token price in the catalog is the rate for the model or provider route. A funding fee is a separate checkout cost. Treat the two as separate lines in a budget, especially if you top up frequently in small amounts. Payment availability also varies by account and checkout method.

To compare a paid workload, use the same model, token mix and request features on both services. Start with input and output, then add cache rates where applicable. Check whether your configuration permits fallback to a more expensive provider, and confirm the quote for the exact route your key can use. The example below compares inference only so you can add funding fees and taxes that apply to your account. LAYSO bills in prepaid platform credits and shows USD reference prices in its catalog.

OpenRouter free models and rate limits

OpenRouter’s :free model variants have a published limit of 20 requests per minute. The daily allowance is generally 50 requests, rising to 1,000 after the qualifying credit purchase. Its documentation describes that tier as a $10 purchase, with a $9 threshold to account for top-up fees. Failed attempts can count against the daily allowance. Other models listed at zero token price can have different funding requirements or upstream limits. Verify the exact model ID before using a zero-price listing in a budget.

For a short trial, pick a model that supports your required request features and keep the test volume below both the minute and daily limits. For longer experiments, check how each service handles exhausted free usage. On LAYSO Activities, each event has its own eligibility, usage window, shared token allocation and request cap. Eligible users create or bind an activity key for the featured model. Paid continuation requires an explicit opt-in and selection of an eligible paid group.

What 60 million tokens cost each month

Suppose a support assistant sends 50 million uncached input tokens and generates 10 million output tokens each month. Both quotes below use the same GPT‑5.4 mini model. Each subtotal is the number of millions of tokens multiplied by the published rate for that direction.

The difference is $41.25 per month, or 50% at these rates. LAYSO shows a USD reference equivalent and deducts platform credits. The example excludes cached tokens, funding fees, taxes and optional extras. Check the GPT‑5.4 mini model page for current routes and prices. If most of your prompts hit the cache, repeat the calculation using the cached input rate.

Move an OpenAI SDK integration in four steps

1. Create a LAYSO API key and store it in the LAYSO_API_KEY environment variable.
2. Set the SDK base URL to https://api.layso.ai/v1 and use the new key.
3. Use the exact model ID from the pricing page. OpenRouter’s openai/gpt-5.4-mini is gpt-5.4-mini on LAYSO.
4. Install the Python SDK with python -m pip install openai, then run the example. Compare output quality, latency and billed usage before redirecting production traffic.

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.layso.ai/v1",
    api_key=os.environ["LAYSO_API_KEY"],
)

response = client.chat.completions.create(
    model="gpt-5.4-mini",
    messages=[{"role": "user", "content": "Write one sentence about API gateways."}],
)
print(response.choices[0].message.content)

Keep provider-specific routing headers separate from your SDK calls. If your application uses tool calling, streaming or JSON schemas, test those paths with the chosen model before switching the rest of your traffic.
