For UX speed orientation we show a speed score of 0/100 and call it “Moderate / variable”—Latency depends entirely on your hardware stack. Context window is 256,000 tokens (Strong for long reports, transcripts, and mid-size repos.). Vision path for images; long PDFs often via text extraction + RAG Tools: Strong — standard tool/function patterns on hosted API. JSON outputs: Yes — JSON / schema-style outputs widely used. Prompt caching: Depends on provider — use catalog cached rate when shown. Benchmark scan pending — live OpenRouter pricing is synced; scores populate after autonomous research.
Price + performance hints
Choosing between DeepSeek R1 and Google Gemini Gemma 4 31B affects your monthly API bill and how snappy your app feels. Skip the hype. Use the calculator above for dollars, then use this page for context limits, caching, and our plain-language hints on speed (0/100 vs 0/100) and rough “smarts” (0/100 vs 0/100). Those hints come from catalog + provider family signals—they are not lab benchmarks—so still try both on real tasks.
API latency and failover paths depend on where you host and which provider region you call. Teams in Australia often verify Sydney (ap-southeast-2) or Singapore edges; US buyers standardize on us-east-1 / us-west-2; Canada frequently maps to the same US regions or dedicated CA endpoints where offered. Our list prices are global list rates—map the model to your closest allowed region in the provider console, then re-run the workspace above with your real traffic split so CFOs and CTOs see numbers tied to production, not a generic blog table.

Benchmark scan pending — live OpenRouter pricing is synced; scores populate after autonomous research. Same idea applies to both sides—use these rows as a starting point, not a verdict.
Every prompt, document, and system message costs input tokens. DeepSeek R1 is $0.14 per million input tokens. Google Gemini Gemma 4 31B is $0.14. For read-heavy workloads, DeepSeek R1 wins. If you process huge documents daily, that gap adds up fast—pick DeepSeek R1 over Google Gemini Gemma 4 31B when quality is similar. Use our calculator above to see exact input costs.
Output tokens are what the model generates. They are usually pricier than input. DeepSeek R1 charges $0.28 per million output tokens; Google Gemini Gemma 4 31B charges $0.4. For long answers, code, or reports, favor DeepSeek R1. Tight prompts ("answer in one paragraph") cut spend on either side. Our calculator helps you estimate these output costs accurately.
Context is how much text fits in one request. DeepSeek R1 allows up to 640,000 tokens. Google Gemini Gemma 4 31B allows up to 256,000. DeepSeek R1 fits longer docs or repos—but you pay for every token you send, every turn. Do not max the window unless you need it. In plain words: Strong for long reports, transcripts, and mid-size repos. For the other side: Strong for long reports, transcripts, and mid-size repos.
DeepSeek R1 is text-only here. Gemma 4 31B supports vision (about $0.005 per image). Resize images before the API when you can—it lowers token load and cost.
Reusing the same long context? Caching can slash input cost. DeepSeek R1 lists cached input around $0.07 per million tokens. Gemma 4 31B does not show a cached rate here. Great for chat over one big PDF or policy doc.
If you do not need instant replies, batch jobs often run at a steep discount (often around half off list price, depending on the provider). Ship a file of requests, get results within about a day. Ideal for summaries, translations, and backfills. Use the calculator toggles above to see how batch mode changes your estimate.
Chats repeat system prompts and history every turn. A short user message can still bill thousands of input tokens. Lower input price helps—DeepSeek R1 is usually safer for high-volume chat. On our speed hints, DeepSeek R1 is 0/100 (Deliberate (reasoning-first)) and Google Gemini Gemma 4 31B is 0/100 (Moderate / variable). If one is clearly ahead on both price and speed hint, that is a nice combo for live chat—but slow networks or huge prompts can still swamp the difference, so try a realistic thread in your region.
Extraction needs accuracy and often a large context for messy PDFs. Try both DeepSeek R1 and Google Gemini Gemma 4 31B on real samples. If quality matches, pick the cheaper input side—extraction is usually input-heavy.
Coding rewards reliability over saving a few cents. Bad output costs engineer time. Our coding-strength hints (again, heuristics) put DeepSeek R1 at 0/100 and Google Gemini Gemma 4 31B at 0/100, with broader “smarts” hints at 0/100 vs 0/100. Between this pair, favor whichever passes your tests on your stack traces and style rules; if quality is a tie, output price leans toward DeepSeek R1 for long patches.
System prompts ride along on every call. Example: 1,000 tokens × 100,000 requests per day ≈ 100M input tokens daily. At $0.14 per million for DeepSeek R1, that is about $14.00 per day from the system prompt alone. Keep instructions short and reusable.
RAG sends retrieved chunks with each question. More chunks mean more input tokens to DeepSeek R1 or Google Gemini Gemma 4 31B. Tighten retrieval: send only the best few passages, not whole folders.
Long prompts tax you every request. Fine-tuning costs upfront but can shorten prompts. Compare total cost in our calculator: long prompt + cheap base model vs short prompt + fine-tuned pricing if you use it.
Agents may call DeepSeek R1 or Google Gemini Gemma 4 31B many times per user task. One workflow can equal dozens of normal chat turns. Cap steps, log spend, and alert on spikes.
Bill clients for API usage you resell. Use Agency Mode in the calculator for markup, client price, and margin—plus PDFs for proposals.
Flat plans get burned by power users on DeepSeek R1 or Google Gemini Gemma 4 31B. Credits or BYOK (bring your own key) align revenue with cost.
Dashboards, alerts, and tools like Helicone or Langfuse show who burns tokens and which prompts bloat bills. Measure before you optimize.
Beyond this pair, consider OpenAI GPT-4o, Anthropic Claude 3.5 Sonnet, or Google Gemini Gemini 1.5 Pro for price or capability fit. Design your stack so you can swap models without a rewrite.
List prices keep falling, but workloads get heavier—bigger contexts, agents, more tools. Net spend can still climb. Keep a running estimate whenever you change models or traffic.
Cost is not everything. DeepSeek R1 carries a speed hint of 0/100 (Deliberate (reasoning-first)); Gemma 4 31B is 0/100 (Moderate / variable).Reasoning models skew slower—plan UX accordingly. Latency depends entirely on your hardware stack. In production you still want time-to-first-token and tokens per second on your prompts, region, and concurrency—especially for voice, typing indicators, or anything that feels “live.”
