Qoder stacked two benefits on 2026-09-18. On the international site, Qwen3.8-Flash is free for a limited window: its billing coefficient drops from 0.1x to 0.0x. At the same time, every personal user can manually claim 100 general Credits each day by logging in. The two benefits are independent and can be enjoyed together, but they live in different places and follow different rules. This is a hands-on SOP to follow step by step: install, log in, confirm the free model, claim daily Credits, manage your balance, and use the window before September 30. All UI paths and rules follow the official event pages; exact menu labels follow the client you actually run. For the backstory of this campaign, see the Qwen3.8-Flash free hotspot on Qoder, and for a cross-tool comparison of free allowances, see the AI coding tool free-credits comparison review.
Benefit overview: two actions to remember
The whole campaign comes down to two actions: pick a model, claim Credits. Action one is the Qwen3.8-Flash limited-time free ride. Inside Qoder its billing coefficient drops from the usual 0.1x to 0.0x during the window, which means every call to Qwen3.8-Flash costs zero Credits. The window runs from 10:00 Beijing time on September 18, 2026 to 23:59:59 on September 30, about 13 days. No claim is needed: select it in the model picker and it is active, even at zero balance. Action two is the daily 100 general Credits. Each round grants 100 general Credits that you can spend on other models under their own rules. You must claim it by hand; login never drops it in. A new round opens at 10:00 UTC+8 every day and stays open until 10:00 the next day; one claim per account per round, no make-up for missed rounds.
Who qualifies? On the international site (qoder.com) the trial free tier, Pro trial, Pro, Pro+ and Ultra all qualify. On Qoder CN (qoder.cn) the trial, Pro, Advanced, Flagship and membership-card tiers all qualify, including free and trial users. New and existing personal users are covered; enterprise subscriptions are out of scope. The international and CN accounts and balances do not interoperate, so Credits claimed on one side stay on that side. The two benefits are independent and never offset.
Download and install: update to the latest build
The daily 100 Credits claim lives inside the client, and the official note says you should install or upgrade to the latest Qoder first. So first get the client current. Qoder ships across desktop, mobile, IDE, the JetBrains plugin and CLI, and granted Credits work everywhere, but claim on the desktop client where the path is clearest.
Download addresses split by version: international at qoder.com, CN at qoder.cn. The desktop download page is qoder.com/download?product=qoder for the international site, with the matching entry on qoder.cn for CN. The installer follows its own wizard, so exact steps follow the client you run. After install, confirm you can reach the official download and event pages:
# Confirm the official download and event pages are reachable (open in a browser to be sure)
curl -I https://qoder.com/download?product=qoder
curl -I https://docs.qoder.com/zh/events/flashofferA 200 or 302 means the network and the official site are fine. Before launching the desktop client, you can also glance at your system info to confirm it meets the desktop minimum:
# Inspect OS and architecture to confirm the desktop client can run
uname -srmWhy update first? The daily claim entry (the gift icon in the bottom-left usage panel) only shows up reliably on newer builds. Older builds may hide the claim button until you upgrade. So if you open the client and cannot find the claim entry, check for updates before assuming you are ineligible.
Sign up and log in: international vs CN
Qoder runs two personal sites: the international qoder.com and the CN qoder.cn. Both are covered this time, but accounts, balances and login methods do not interoperate, so decide which one you are on before mixing up the rules. For the differences and which to pick, see the Qoder international vs CN comparison review.
The international site uses email or third-party accounts and documents at docs.qoder.com; the CN site lives at qoder.cn with docs at docs.qoder.cn and login and payment tuned for domestic users. On either version, any personal user (free, trial, or membership card) qualifies; enterprise plans are excluded. After sign-up, logging in with the same account shares the consumption of one balance across desktop, IDE, the JetBrains plugin, CLI, QoderWake, Cloud Agents, mobile and web. This is shared consumption, not shared asset, and the two versions cannot transfer balances.
A small reminder: if you hold accounts on both versions, you do get two independent benefits you can claim and use separately. But within one version, each account may claim the daily reward only once per round; do not try to farm the same allowance with many throwaway accounts on one version, since benefits are settled against the account state at claim time and abnormal accounts may be reclaimed.
Confirm the free model: pick Qwen3.8-Flash
Confirming the free model is the easiest step in this SOP because it needs no claim, only the right selection. Open the Qoder desktop client, find Qwen3.8-Flash in the model picker and select it. From 10:00 on 2026-09-18 its billing coefficient shows 0.0x and calls are free. How do you confirm it is on? Two signals: the model should show a limited-time-free marker next to it in the picker (exact wording follows the client), and after you start a conversation or task, the usage panel should show no deduction for that call, with both plan Credits and the add-on pool untouched.
Qwen3.8-Flash is Qwen's open-weight multimodal MoE model, strong at coding, long-document processing, image understanding and tool use, balancing capability, latency and cost. It is a strong zero-cost base for routine code, docs, data and images. If you want to run it inside your own network to keep sensitive code on-prem, see the Qwen3.8-Flash local deployment SOP and the Qwen3.8-Flash next-gen resource roundup.
Scope matters: this free ride covers only Qwen3.8-Flash inside Qoder. Other models (such as Qwen3.8-Max or the Qwen3.7 line) and other tiers still bill at their own coefficients; read the model name before you pick. The Flash free ride and the daily 100 Credits are two separate lines: Flash costs no Credits, and the Credits you claim are reserved for other models, enjoyed together without offset.
Daily 100 Credits claim rhythm
The daily login reward must be claimed by hand; that is the biggest difference from the model free ride. The official claim path is: open the Qoder desktop client, go to the bottom-left usage panel, find the gift icon, click it, then click the claim button. Users also share an equivalent path: click "view my usage" at the bottom left, then the gift icon, and the claim window pops up; click claim. Exact button text follows the client, but the entry logic is the same, near the bottom-left usage panel.
Lock in the timing: a new round opens at 10:00 UTC+8 every day and stays open until 10:00 the next day; one claim per account per round, 100 general Credits each, no make-up, and unclaimed Credits do not roll into the next round. Each grant is valid for 30 days from its claim date, and unexpired grants accumulate across days. Example: claim 100 today and spend 20, then claim 100 tomorrow, and your usable total is 180; today's grant counts down from today's claim time, tomorrow's from tomorrow's, two separate clocks, not one never-expiring balance.
The grant lands in Add-on Credits, also called the resource pool. Its reach is wide: after claiming, the same account can spend it on Qoder, Qoder IDE, the Qoder JetBrains plugin, Qoder CLI, QoderWake, Qoder Cloud Agents, mobile and web. A practical rhythm: make claiming the first thing you do every time you open Qoder, a quick tap, so you never find the window closed when you actually need it.
Usage management: let Flash carry the base load
Claiming and spending are two steps; managing them is what keeps both from going to waste. First, the deduction order: the daily reward belongs to the resource pool, and the system spends the earliest-expiring Credits first; when several grants share the same expiry, it spends plan Credits before the resource pool. That means your daily 100 Credits are last-in but earliest-out, so plan to keep near-term spend fresh rather than claiming two weeks of allowance up front and letting it sit. You can claim ahead if you like, just remember each grant expires on its own 30-day clock.
The management strategy is simple: use free Qwen3.8-Flash as the base, and reserve your limited plan Credits and daily general Credits for the genuinely hard tasks. Route high-frequency batchable work (code, docs, data, images, routine Q and A) to Flash by default so it never touches your pool; save the few heavy end-to-end jobs (complex architecture, long autonomous runs, top-tier reasoning) for paid models you stockpiled. With this combo, most daily work during the free window costs almost nothing, and you spend only on the cutting edge.
How do you watch the burn? Open "view my usage" at the bottom left; the panel shows plan Credits and resource-pool remaining and used percentages, plus the expiry of each grant. Build the habit of checking the usage panel before and after big tasks to confirm Flash calls really deducted nothing and paid-model calls hit the grant you expected. Benefits settle at claim time, and later plan changes do not alter resource-pool expiry.
Window planning: use it up before 9/30
Time is the scarcest resource. The Qwen3.8-Flash free window is only about 13 days, from 10:00 on September 18 to 23:59:59 on September 30 Beijing time; the daily 100 Credits campaign has no announced end date and can in principle keep running. So plan in two layers: use the free model now, let daily Credits trickle.
Inside the free window, schedule the big blocks you would normally hate to spend allowance on: a full feature upgrade of an existing project, turning an idea into a runnable site or app, turning a batch of raw data into a visual analysis report, or building a sourced research brief on a topic. These tasks call a lot per run and run long, so they are cheapest inside the Qwen3.8-Flash free period. After 23:59:59 on September 30, Qwen3.8-Flash returns to its 0.1x coefficient and normal Credit billing resumes.
The daily 100 Credits need no rush: claim at 10:00, roll on a 30-day clock, accumulate. A common misread is treating both benefits as ending the same day; only the Flash free ride has a deadline, while the daily reward has none (subject to later official notice). So after October you can still claim 100 Credits daily, only Flash is no longer free, and you then feed your stockpiled allowance to the models still worth paying for. Before the window closes, write a short list: which projects must run on Flash before 9/30, and which can wait for daily Credits.
FAQ
question
My Credit balance is already zero; can I still use Qwen3.8-Flash? A1: Yes. During the campaign, selecting Qwen3.8-Flash is free at a 0.0x coefficient and needs no remaining balance, so it works even at zero. That is exactly its value as a fallback workhorse: when allowance runs dry, Flash still finishes the job.
question
Do the daily 100 Credits arrive automatically, and can I make up a miss? A2: They do not arrive automatically; you must claim them by hand. The claim entry is the gift icon in the bottom-left usage panel, a new round opens at 10:00 UTC+8 and stays open until 10:00 the next day, one claim per account per round, no make-up, and unclaimed Credits do not roll forward. Make claiming the first thing you do each time you open Qoder.
question
Do international and CN (Qoder CN) balances interoperate? A3: No. The two versions keep separate accounts and balances; Credits claimed on the international site are spent only in the international system, and CN Credits only in the CN system, with no transfer between them. Within one version, though, desktop, IDE, plugin, CLI, mobile and web share the consumption of the same account balance.
question
Do the two benefits offset each other? A4: No. Calling Qwen3.8-Flash spends no Credits and does not deduct the 100 you claim daily; the daily reward is spent only on other models under their own coefficients. They are independent and can be enjoyed together. Short version: Flash free runs on the model line, daily Credits run on the allowance line, no interference.
question
How is Qwen3.8-Flash billed after September 30? A5: The campaign ends at 23:59:59 Beijing time on 2026-09-30, after which Qwen3.8-Flash returns to its 0.1x coefficient and calls bill normally at the then-published rate. Daily Credits you already claimed still expire on their own 30-day clocks and are unaffected. Other models always bill under their own rules.
