Best for: Reasoning-heavy analytics, tutoring, and internal tools on a budget
Best for: General text generation and chat
DeepSeek R1 is offered by DeepSeek as part of the hosted API lineup. List prices here are $0.14 per million input tokens and $0.28 per million output tokens. In this catalog it is set up as text-in, text-out. If you repeat the same long system prompt, cached input can drop toward about $0.07 per million tokens in our catalog snapshot (enable “Use Cached Pricing” above to model it). On our catalog benchmarks (0–100, not official vendor scorecards): composite 0/100, coding 0/100, logic/reasoning 0/100, math 0/100, and instruction following 0/100. For UX speed orientation we show a speed score of 0/100 and call it “Deliberate (reasoning-first)”—Reasoning models skew slower—plan UX accordingly. Context window is 640,000 tokens (Strong for long reports, transcripts, and mid-size repos.). Large single-shot context — fewer chunks for long PDFs / repos (still extract text per API rules) Tools: Strong — standard tool/function patterns on hosted API. JSON outputs: Usually yes on major hosted APIs; validate on your stack. Prompt caching: Yes — ~$0.07/M cached input. Benchmark scan pending — live OpenRouter pricing is synced; scores populate after autonomous research.
Z.ai GLM 5 Turbo is offered by Z.ai as part of the hosted API lineup. List prices here are $0.1 per million input tokens and $0.1 per million output tokens. In this catalog it is set up as text-in, text-out. On our catalog benchmarks (0–100, not official vendor scorecards): composite 83/100, coding 88/100, logic/reasoning 84/100, math 60/100, and instruction following 98/100. For UX speed orientation we show a speed score of 70/100 and call it “Moderate / variable”—Measure TTFT/TPS on your region and prompt shape. Context window is 128,000 tokens (Standard for chat + medium docs; chunk bigger sources.). Typically text-in via your ingestion pipeline; size to context limit Tools: Check provider docs for your endpoint. JSON outputs: Usually yes on major hosted APIs; validate on your stack. Prompt caching: Depends on provider — use catalog cached rate when shown. Catalog Benchmarks (0–100). Manually maintained model-level scores; verify on your own evals.
Price + performance hints
Choosing between DeepSeek R1 and Z.ai GLM 5 Turbo 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 70/100) and rough “smarts” (0/100 vs 83/100). 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. Z.ai GLM 5 Turbo is $0.1. For read-heavy workloads, Z.ai GLM 5 Turbo wins. If you process huge documents daily, that gap adds up fast—pick Z.ai GLM 5 Turbo over DeepSeek R1 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; Z.ai GLM 5 Turbo charges $0.1. For long answers, code, or reports, favor Z.ai GLM 5 Turbo. 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. Z.ai GLM 5 Turbo allows up to 128,000. 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: Standard for chat + medium docs; chunk bigger sources.
DeepSeek R1 is text-only here. GLM 5 Turbo is text-only here. 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. GLM 5 Turbo 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—Z.ai GLM 5 Turbo is usually safer for high-volume chat. On our speed hints, DeepSeek R1 is 0/100 (Deliberate (reasoning-first)) and Z.ai GLM 5 Turbo is 70/100 (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 Z.ai GLM 5 Turbo 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 Z.ai GLM 5 Turbo at 88/100, with broader “smarts” hints at 0/100 vs 83/100. Between this pair, favor whichever passes your tests on your stack traces and style rules; if quality is a tie, output price leans toward Z.ai GLM 5 Turbo 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 Z.ai GLM 5 Turbo. 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 Z.ai GLM 5 Turbo 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 Z.ai GLM 5 Turbo. 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)); GLM 5 Turbo is 70/100 (Moderate / variable).Reasoning models skew slower—plan UX accordingly. Measure TTFT/TPS on your region and prompt shape. 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.”
Check training, retention, and region rules for each provider behind DeepSeek R1 and GLM 5 Turbo. Regulated data needs enterprise terms, not guesswork.
Proprietary APIs are simple but price-controlled. Open models (e.g. Llama family) add ops work but can cut unit cost at scale. Match the tradeoff to your team.
