Are There Free DeepSeek V4 Flash Tokens? How to Get Set Up and Start Coding | TeamoRouter

Quick Answer

DeepSeek V4 Flash is available on TeamoRouter through the lower-priced deepseek-v4-flash-free model ID. It is not free: the tier is billed at a lower rate, and new accounts start at a $0 balance, so you top up (from $5) before the first call. It also has a daily request cap (see Rate limits). The -free tier gives you access to the same DeepSeek V4 Flash model as the standard tier: 284B MoE with 13B active parameters, 1M-token context window, MIT license, and thinking mode on by default. This guide walks through every step — registration, top-up, your first API call, and how to switch to the standard tier when you need more volume.

Why a Lower-Priced Tier on a Model This Capable Is Unusual

Let us be direct about what is happening here. DeepSeek V4 Flash, released July 31, 2026, is a genuinely competitive coding model. It scores 82.7 on TerminalBench 2.1, 76.7 on Cybergym, and 68.7% on DSBench-FullStack — numbers that put it in the same conversation as models costing 30-100x more. Its official API pricing — $0.30/$1.20 per million tokens at peak, half that off-peak — already makes it one of the cheapest major LLM APIs of 2026.

On TeamoRouter it also comes as a lower-priced -free tier — still billed, with a daily request cap, and new accounts top up from $5 before the first call.

Most cheap or free tiers in the AI API space come with significant catches: severely rate-limited models, older versions, stripped-down feature sets, or aggressive upsells the moment you hit the limit. The deepseek-v4-flash-free tier on TeamoRouter is different — it is the same model, same context window, same thinking mode, same MIT-licensed weights. What differs is the lower rate and a daily request cap.

Step 1: Register on TeamoRouter

Go to TeamoRouter and click Sign in. In the dialog, choose Continue with Google or register with your email. To use a phone number instead, click Use phone instead. TeamoRouter supports Alipay, WeChat Pay, and international cards, so developers in China and globally can sign up without friction.

After registration you land on the dashboard, where you top up and create keys.

Step 2: Top Up Before Your First Call

New accounts start at a $0 balance. deepseek-v4-flash-free is a lower-priced tier, not a free one — every request is billed — so top up (from $5) before your first call. The model ID to use is deepseek-v4-flash-free.

Your keys are always available under API Keys in the left sidebar.

No manual activation is required: once your account has a balance, your key can call deepseek-v4-flash-free.

Step 3: Find Your Model ID and Rate Limit Page

The key details live in two places:

1. Model page (/models/deepseek-v4-flash-free) — the model ID and its current price.
2. Rate limits page (/docs/rate-limits) — the daily request cap for -free models and when it resets.

If you hit the daily cap before the reset, the API returns an HTTP 402 error (free_request_quota_exhausted). Your options at that point are covered in Step 6 below.

The model ID you use in your code is exactly:

deepseek-v4-flash-free

This is the string you pass to the model parameter in every API call. It is separate from the standard deepseek-v4-flash model ID, so you always know which rate a request is billed at.

Step 4: Get Your API Key

From the dashboard, navigate to API Keys in the left sidebar. Click Create Key, give it a name (e.g., "free-tier-coding"), and copy the resulting key. It starts with sk-teamo-.

Keep this key secure. The -free tier uses the same security model as the standard tier — your key is scoped to your account, and usage is billed to your balance and counts against your daily cap.

Step 5: Make Your First API Call

The TeamoRouter API is OpenAI-compatible, which means you can use any OpenAI SDK, curl, or HTTP client you already have set up. Just change the base URL and the key.

curl

curl https://api.agentapiai.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-teamo-your-key-here" \
  -d '{
    "model": "deepseek-v4-flash-free",
    "messages": [
      {"role": "user", "content": "Write a Python function that validates an email address using regex."}
    ]
  }'

The response is standard OpenAI chat completions format:

{
  "id": "chatcmpl-xxx",
  "object": "chat.completion",
  "model": "deepseek-v4-flash-free",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "import re\n\ndef validate_email(email: str) -> bool:\n    ..."
      },
      "finish_reason": "stop"
    }
  ],
  "usage": {
    "prompt_tokens": 22,
    "completion_tokens": 145,
    "total_tokens": 167
  }
}

Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    api_key="sk-teamo-your-key-here",
    base_url="https://api.agentapiai.com/v1",
)

response = client.chat.completions.create(
    model="deepseek-v4-flash-free",
    messages=[
        {"role": "system", "content": "You are a senior Python engineer. Write clean, typed code with docstrings."},
        {"role": "user", "content": "Write a function that retries an HTTP request with exponential backoff and jitter."}
    ],
    max_tokens=1024,
)

print(response.choices[0].message.content)
print(f"Tokens used: {response.usage.total_tokens}")

Codex config.toml

If you use OpenAI Codex, add a profile for the -free tier. In your Codex config file (typically ~/.codex/config.toml):

[model_providers.teamorouter]
name = "TeamoRouter"
base_url = "https://api.agentapiai.com/v1"
env_key = "OPENAI_API_KEY"
wire_api = "responses"

[profiles.teamorouter-free]
model_provider = "teamorouter"
model = "deepseek-v4-flash-free"

Then launch Codex with:

export OPENAI_API_KEY="sk-teamo-your-key-here"
codex --profile teamorouter-free

Codex will route all its model calls through TeamoRouter to the lower-priced DeepSeek V4 Flash -free endpoint. Each call the agent makes is billed and counts as one request against your daily cap.

Step 6: What Happens at the Daily Cap

When you hit the daily cap, the API returns HTTP 402 with "type": "free_request_quota_exhausted". The message is currently in Chinese; it tells you to switch to deepseek-v4-flash and that the cap resets at 00:00 the next day (UTC+8):

{
  "error": {
    "message": "您的deepseek-v4-flash免费额度已耗尽。如需继续使用，请更换模型代号为deepseek-v4-flash。deepseek-v4-flash额度次日0点刷新。",
    "type": "free_request_quota_exhausted",
    "code": 402
  }
}

You have two options at this point:

1. Wait for reset — the counter resets once a day (see Rate limits). If you are close to the reset, just pause and resume after it.
2. Switch to the standard tier — use the deepseek-v4-flash model ID for requests without the daily cap. The standard model is the same V4 Flash, billed at the standard rate. See the pricing page for current rates.

To switch, top up your TeamoRouter balance if needed (Alipay, WeChat Pay, international card, or USDT) and replace deepseek-v4-flash-free with deepseek-v4-flash in your code. Everything else — API key, base URL, request format — stays identical.

What the Daily Cap Means in Practice

A "request" is one API call — one turn of conversation, one code generation, one completion. If you are using the chat completions endpoint, multi-turn conversations count each turn as a separate request. If you are running an agent loop where the model calls tools and receives responses, each round-trip counts.

Realistic daily usage on the -free tier:

Each of these is one request, so the daily cap goes furthest when you batch work into fewer, larger requests. For teams, each member uses their own account with its own daily cap.

Step 7: -free Tier Limitations (Honest List)

The -free tier is the real model, but it has limits:

• Billed per use. Every request is billed to your balance at the lower -free rate, and new accounts top up (from $5) before the first call.
• Daily request cap, hard limit (Rate limits). No rollover, no bursting, no carry-forward. The model has a max output of 384K tokens per request.
• No priority queue. -free requests share the same infrastructure as standard requests, but standard traffic may get priority during congestion. In practice, latency has been sub-second to ~2 seconds for both tiers.
• No vision. V4 Flash is text-only regardless of tier. This is a model limitation, not a -free tier restriction.
• Thinking mode is on by default. This is a feature, but it means temperature and top_p have no effect unless you explicitly disable thinking. Fill-in-the-middle (FIM) completion only works in non-thinking mode.

Why TeamoRouter Offers This

TeamoRouter is a multi-model API gateway that gives developers a single key to access DeepSeek, Claude, GPT, Gemini, Kimi, and other models. The -free tier is a straightforward acquisition play: let developers try the platform and the V4 Flash model at a low per-use cost, and when they need more volume or want to add other models (Claude Opus 5.5 for architecture, GPT-6.1 Sol for vision tasks), they are already on the platform with a working integration.

From a developer's perspective, this is a genuinely good deal. You get a capable coding model at a lower rate, and when your needs grow, you do not have to change APIs, keys, or SDKs — just switch the model ID string and add funds.

What Standard V4 Flash Gets You

When you need more than the daily cap allows, the standard deepseek-v4-flash model ID gives you:

The same balance also covers TeamoRouter's full feature set: cost controls, team management, and access to every other model on the platform — Claude Opus 5.5, GPT-6.1 Sol, DeepSeek V4 Pro, and more (see pricing).

Code Example: Switching from -free to Standard

The migration is a one-word change. Here is the same Python example, first on the -free tier, then on the standard tier:

from openai import OpenAI

client = OpenAI(
    api_key="sk-teamo-your-key-here",
    base_url="https://api.agentapiai.com/v1",
)

# -free tier (lower-priced, still billed; daily request cap)
free_response = client.chat.completions.create(
    model="deepseek-v4-flash-free",
    messages=[{"role": "user", "content": "Write a sorting algorithm in Rust."}],
)

# Standard tier (no daily cap, billed per token)
paid_response = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[{"role": "user", "content": "Optimize this sorting algorithm for cache locality."}],
)

Everything else — the client setup, the base URL, the API key, the request structure — is identical between the -free and standard tiers. This is the single strongest argument for starting on the -free tier: when you grow out of it, the migration is a find-and-replace on the model ID string.

How to Make Every Request Count

If you are operating within the -free tier's daily cap, a few habits maximize what you get from each call:

1. Combine prompts. Instead of "Write function A" then "Write function B," ask for both in one request. A 384K-token output ceiling means you can generate a lot of code per call.
2. Use system prompts. A strong system prompt ("You are a senior Rust engineer, write idiomatic code with error handling and doc comments") makes every response production-quality from the first attempt, reducing the need for follow-up refinements.
3. Batch similar tasks. If you need tests for three modules, ask for all three in one request rather than three separate calls.
4. Track your usage. Check your request history in the TeamoRouter dashboard so the daily cap does not catch you mid-session.
5. Save complex architecture questions for stronger models. V4 Flash is an executor, not a planner. Use your -free requests for code generation, test writing, and reviews; route multi-file architecture planning to a stronger model (V4 Pro or Claude Opus 5.5) when you need that depth. To set up Opus 5.5 in Claude Code, see Claude Opus 5.5 API pricing and Claude Code setup.

The Bottom Line

The DeepSeek V4 Flash -free tier on TeamoRouter is a developer-friendly way into V4 Flash. It is billed at a lower rate with a daily request cap, the model is the same V4 Flash as on the standard tier, and moving to the standard tier is a one-word change in your code. Register at TeamoRouter, top up from $5, grab your API key, set your model to deepseek-v4-flash-free, and start coding.

FAQ

Is the DeepSeek V4 Flash free tier really free?

No. Despite the -free suffix, deepseek-v4-flash-free is a lower-priced tier that is still billed. New accounts start at a $0 balance, so top up (from $5) before your first call. It also has a daily request cap; see Rate limits.

What happens when I hit the daily cap?

The API returns an HTTP 402 error (free_request_quota_exhausted). You can either wait until the daily reset, or switch to the standard deepseek-v4-flash model ID, which has no daily cap and is billed per token at the standard rate (see pricing).

Is the -free model the same as the standard V4 Flash?

Yes. It is the same DeepSeek V4 Flash model — 284B MoE with 13B active parameters, 1M-token context window, thinking mode on by default, MIT license. The differences are the lower rate and the daily request cap.

Can I use the -free tier with Codex or Claude Code?

Yes. Codex has official V4 Flash integration — use the TeamoRouter base URL and the deepseek-v4-flash-free model ID in your config.toml. Claude Code connects through TeamoRouter's Anthropic-compatible endpoint instead: set ANTHROPIC_BASE_URL=https://api.agentapiai.com (no /v1) and use the same model ID.

Does the -free tier support the Responses API?

Yes. V4 Flash was the first DeepSeek model with native OpenAI Responses API support. Both the -free (deepseek-v4-flash-free) and standard (deepseek-v4-flash) model IDs work with the Responses API through TeamoRouter.

How do I move from the -free tier to the standard tier?

Top up your TeamoRouter balance via Alipay, WeChat Pay, international card, or USDT, then change the model ID in your code from deepseek-v4-flash-free to deepseek-v4-flash. No other configuration changes are needed.

Where can I monitor my -free request usage?

The daily cap is listed on the Rate limits page; your requests and spend show up in your TeamoRouter dashboard.
