Should this workload run on a frontier LLM or a small language model?

Describe your workload. We compare 10 models — frontier LLMs and SLMs — on monthly cost, accuracy on your specific task, latency fit, and data residency. The right hosting mode comes with the answer.

How it works

Three inputs, one decision.
No tokens, no spreadsheets.

  1. Describe

    Tell us about the workload.

    Nine inputs: task, volume, token profile, accuracy tolerance, latency SLA, residency, language, current spend. About 90 seconds.

  2. Score

    A rule engine, not vibes.

    Hard filters cut anything that fails residency, language, or accuracy. Soft scores rank cost (35%), accuracy on your task (35%), latency fit (15%), and sovereignty bonus (15%).

  3. Decide

    Top-3 with a hosting mode.

    Side-by-side cost across 10 models. The right hosting mode (API / managed / self-host / on-prem). A savings number against what you pay today.

Who this is for

Built for the moment your AI bill becomes a board conversation.

  • CTO / VP Engineering

    AI bill grew 5× — questioning whether you still need a frontier LLM. The shortlist + break-even tells you.

  • CFO / Finance

    Need a defensible savings number for the board. Plug in current spend; the result is in dollars.

  • Head of AI / ML Lead

    Running architecture review. Top-3 with fit scores + accuracy deltas; PoC-ready in a week.

  • Sovereign-AI tech founder

    Residency or national-AI policy is the primary filter. Tool surfaces region-aligned SLMs (Mistral, Qwen, Falcon, BharatGen) on merit.

Methodology

Deterministic. Reproducible. Cited.

The scoring engine is rule-based — no LLM calls on the hot path. Same inputs always produce the same shortlist. Pricing refreshes monthly via the shared Buzzi LLM Pricing Database (Tool 01) with a daily snapshot cron catching mid-month moves. Benchmarks are cited per source, not invented.

No vendor sponsorships.

Pricing is not pay-to-play.

FAQ

Common questions about SLM vs LLM.

What does this tool do?

It takes nine details about your AI workload — task, volume, token profile, accuracy tolerance, latency SLA, residency, language, current spend — and returns a side-by-side monthly cost across 10 models, an accuracy delta on your task, the right hosting mode, and a top-3 shortlist with fit scores. No login, runs in 90 seconds.

How is this different from the LLM Pricing Comparison tool?

LLM Pricing Comparison compares token prices across models you pick. This tool picks models for a workload you describe. Same dataset, two lenses for two different buyer moments.

What's the difference between an SLM and an LLM?

SLM ≈ Small Language Model, typically 1–10B parameters with task-specific accuracy that matches frontier models on narrow tasks at a fraction of the cost. LLM = frontier general-purpose models like GPT-5, Claude Opus 4.7, Gemini 2.5 Pro that are stronger on agentic and reasoning workloads.

When does a small language model win?

Classification, extraction, summarization, translation. Cost-sensitive workloads at high volume. Residency-constrained deployments. Latency-critical paths where every millisecond counts. Anywhere accuracy on the specific task is good enough at much lower cost.

What assumptions does the cost formula make?

Monthly volume × average input tokens × published input price + monthly volume × average output tokens × published output price. Caching discount of up to 90% applied per cache-hit-rate; batch discount up to 50% applied when "Batch-tolerant" is selected. Self-hosted cost adds amortized setup + GPU monthly.

How much do caching and batch discounts change the numbers?

Up to 90% off the input portion when cache-hit-rate is 100% (rare). 50% off the total when batch mode is selected. Real workloads typically see 20–40% savings from caching, 50% from batch on async workloads.

How accurate are the benchmark scores?

They are public-benchmark proxies, not your workload. Strongly recommend a 100–500 sample PoC before committing. Benchmarks come from Artificial Analysis, HuggingFace Open LLM Leaderboard, Stanford HELM, HumanEval / MBPP, AgentBench, plus task-specific suites.

How do I pick the right hosting mode?

Use the matrix: under 100K queries/month → API. 100K–1M with EU residency → managed inference in EU. >1M with sub-second latency → self-hosted GPU. On-prem or air-gapped requirements → open-weight SLM on your hardware.

When does self-hosted beat API?

Typically past 1M–10M queries/month depending on token profile. The break-even chart on the results page shows the exact crossover for your inputs.

How do I size a GPU for self-hosted Llama 3 / Phi-3 / Mistral?

Use the min_vram_gb column on each model card. Phi-3.5 Mini fits on an L4 (24GB). Llama 3.x 8B + Mistral 7B comfortably on a single A100 40GB. Llama 3.3 70B needs 2× A100 80GB minimum at production throughput.

What are the implications of data residency?

Frontier APIs offer some regional hosting (Anthropic EU, OpenAI EU via Azure, Gemini in EU/SG/IN). For strict on-prem only open-weight SLMs apply: Llama, Mistral, Phi, Qwen, Falcon, BharatGen.

Which models are best for multilingual workloads?

Qwen for Chinese / Japanese / Korean. Mistral for European languages. Llama 3.x for broad multilingual baseline. GPT-5 / Claude Opus / Gemini 2.5 Pro for global coverage when budget allows.

What regional SLMs should I know about?

Mistral (EU sovereign), Falcon (UAE / TII), Qwen (APAC), BharatGen (India). The tool surfaces these neutrally on cost + compliance + language merit when residency is selected — not by default.

How often is the data updated?

Pricing — monthly vendor refresh + human review, with a daily snapshot cron catching mid-month moves. Benchmarks — quarterly. Sovereign-model coverage — quarterly + as new models ship.

Does Buzzi have a vendor bias?

No. No vendor sponsorships, no pay-to-play placement, every benchmark cited with source URL and capture date. We list all models we track and rank them on cost, accuracy, latency, residency — not relationships.
