Most people assume that getting your hands on a modern language model means opening an account with one of the big labs, handing over a credit card and bracing for the bill. Free AI API access says otherwise — and it isn't just a one-week trial trick. A roundup published on Habr, backed by hands-on testing, lists ten API routers that offer long-term free or near-free access to DeepSeek, GLM, GPT and a few other models. Two of them are documented down to the exact model IDs, prices and error messages; the rest are named and put through the same checklist.
Everything below is a snapshot of that hands-on check. Prices, quotas and model names in this space move fast, so verify on the provider's own pricing page before you build anything on top of it.
What happened
The reviewer didn't just collect sign-up pages. They registered, looked at the balance, sent real API calls and recorded what came back — including whether the site opens without a VPN from three server nodes in Moscow and St. Petersburg, whether the interface can be switched into Russian, and whether you can pay in rubles rather than dollars. That last part matters to a Russian audience; the rest of us can read it as a useful stress test of how mature each service is.
What an API router actually is
An API is the drive-through window of software. You don't walk into the kitchen — you pull up, say what you want in a fixed format, and food comes out the other side. A router is the switchboard in between. Instead of opening ten separate accounts with ten separate AI providers, you point your code at one address, and the router forwards each request to whichever model you asked for.
Two more terms you'll bump into. A token is a chunk of text — roughly three-quarters of a word in English. A context window is how much the model can hold in its head at once, like the size of a desk before papers start falling off. TeamoRouter's promo models advertise a 1 million token window, which is a whole lot of desk.
OrcaRouter: five free models on a $0.00 balance
OrcaRouter opens without a VPN and the interface can be switched to Russian, though ruble payment isn't supported. After registration the balance sits at $0.00 — no starting bonus. What you do get is five genuinely free models: DeepSeek V4 Flash Free, GLM 5.3 Flash Free, Tencent Hy3 Free, Tencent Hy4 Preview Free and OrcaVerify Text 1.0 Free.
All five answered test calls correctly, with the expected `model` field in the response. There's also a sixth route, `orcarouter/free`, which picks a model for you automatically — handy, but the quota is small: after a few test requests it starts returning `free_quota_exhausted`. Rate limits apply, and cost per call is $0.
TeamoRouter: 99.9% off, while the promo lasts
TeamoRouter also opens without a VPN, its API endpoint answers, the interface switches to Russian, and ruble payment works. There's no starting bonus either — to test properly, the reviewer put $10 on the account.
Three promo models are marked Free: DeepSeek V4.1 Flash Free, DeepSeek V4 Flash Free and GLM-5.3-Flash-Free. At check time they were billed at 0.1% of the normal rate — a 99.9% discount — with a 1 million token context window on all three. The catch is that it's a time-limited promotion, so the pricing page is the source of truth. Test calls came back as `deepseek-v4-1-flash-260910`, `deepseek-v4-flash-ga-260731` and `glm-5.3-flash` respectively, all working.
The other eight names on the list
The same roundup covers Srazu, RockAPI, OpenRouter, llmgw, VseGPT, Token Harbor, NaraRouter and FreeRouter, put through the same checklist. Full test results for those eight weren't in the part of the article I saw, so treat them as leads to explore rather than verified numbers. OpenRouter, at least, is a name plenty of English-speaking developers already know.
What it means for you
Here's the thing: you don't need to be a programmer to benefit. Anyone who can paste a key into a tool — or ask an AI assistant to write the code for them — can put a free router to work. A few real-world versions of that.
At home: a helper that costs nothing
Say you've got a 40-page insurance document and no patience. Wiring DeepSeek V4 Flash Free into a simple chat interface gives you a summarizer you can ask follow-up questions. Because the model is free and the router eats the plumbing, your only real cost is the ten minutes it takes to set up. The rate limits mean it's fine for a few questions at a time, not for hammering all evening.
At work: drafting without a purchase order
If you're in marketing ops and want to auto-tag a batch of support tickets by topic, buying an enterprise plan for a one-off job is silly. Point a script at a free model, run it once, done. The 1 million token context window on TeamoRouter's promo models means you can feed in long documents — contracts, transcripts, whole spreadsheets of text — without chopping them up first.
For a small business: a chatbot you can actually afford
Customer-facing bots get expensive fast because every visitor burns tokens. A near-free route changes the maths. You could run a product Q&A bot on a promo model and keep a paid provider as the fallback for when the discount ends, which is exactly the kind of thing a router makes easy — swap one model name, keep the rest of your code.
For students and creators
Two uses, one setup. Students get a study buddy that will explain a concept five different ways without a subscription. Creators get a brainstorming engine for titles, hooks and outlines. If you'd rather test-drive models in a browser before touching any code, there's a decent pile of free AI tools worth bookmarking — a good way to figure out which model you actually like before you wire up an API key.
As a side income
Freelancers who build small automations — a summarizer for a podcast, a captioning tool for a shop's Instagram — usually eat the API cost themselves. On a $0 or 99.9%-off model, a modest fixed-price gig has a lot more margin. The risk is obvious: when the promo ends, your cost base changes overnight, so price your work with that in mind.
How to try it right now
Start with the free option, then graduate to the discounted one.
1. Open OrcaRouter and create an account. No card needed, no starting credit — just a $0.00 balance and five free models.
2. Grab your API key from the dashboard and switch the interface language if you'd prefer something other than English.
3. Send one test request to DeepSeek V4 Flash Free. Ask it something trivial like "summarize this paragraph." Check that the reply includes the model field — that's how you know the router really routed it.
4. Stay away from `orcarouter/free` for anything serious. It works, but a handful of calls can burn the quota and you'll get `free_quota_exhausted` back.
5. When you need longer documents, move to TeamoRouter. Register, top up the smallest amount you're comfortable with — the reviewer used $10 — and pick one of the three promo models marked Free.
6. Point the same code at the new address. Because it's an OpenAI-compatible style endpoint, you usually only change the base URL and the model name.
7. Set a reminder to check pricing monthly. The 99.9% discount is explicitly time-limited, and free tiers shift without much warning.
Upsides and what changes
The obvious win is that the price of experimenting drops to zero. Not long ago, testing three models against your own data meant three sign-ups and three bills. Now you can compare DeepSeek, GLM and Tencent side by side in an afternoon and only pay for whatever survives the test.
The second win is portability. A router means your code talks to one address, so swapping the model underneath is a one-line change rather than a rewrite. That's a real hedge against a provider changing its terms — which, as both OrcaRouter's quota behaviour and TeamoRouter's limited-time promo show, they do.
And for freelancers and small teams, near-zero inference costs change what's worth building. Automations that weren't viable at $30 of tokens a month suddenly are.
Limitations
Be clear-eyed about this: these are promotional and free-tier routes, not a foundation for a business that can't afford to fall over. OrcaRouter has no starting credit, the catch-all free route runs dry after a few requests, and rate limits are in place — so a burst of traffic will simply fail. TeamoRouter's 0.1% pricing is explicitly a limited-time promotion, and you have to fund the account before you can test anything. Neither is a substitute for a paid contract with a service-level agreement if you're building something customers rely on. Model names, quotas and even the exact models behind a label change without notice, the reviewer verified everything on a single day, and availability from your country or your home ISP may differ from a server node. Treat free tiers as a place to prototype, and budget for a paid fallback before you ship.
Conclusion
Ten API routers now offer free or nearly free access to DeepSeek, GLM and GPT-class models, and the numbers are concrete: five free models and a $0.00 balance on OrcaRouter, three promo models at 0.1% of list price with 1 million token context windows on TeamoRouter. It's the cheapest on-ramp to AI that's existed so far — provided you treat it as an on-ramp and not a forever home.
One action for today: open OrcaRouter, create a free account and send a single test request to DeepSeek V4 Flash Free. Ten minutes, no card, and you'll know whether this whole router thing fits how you work.
