All calculatorsThe short answer
1,179 LLM development companies are listed. 61% publish a minimum project budget; the median floor is $10k. Most work starts in the $3–10k range. Median published rate is $25/hr across 69 companies.
Best supplied: United States (182) · India (131) · Ukraine (59)
Recalculated 2026-10-19 from live profiles.
What it costs, by country
Each cell counts companies whose published minimum project budget falls in that band. Only countries with at least 5 listed companies appear.

How this table is built
- Figures are minimum project budgets companies publish on their own profiles — the floor below which they decline work, not the price of a finished project.
- USD only. Companies quote in six currencies and averaging across them produces a number nobody charges.
- Budgets outside $300–$2,000,000 and rates outside $5–$500/hr are dropped as data-entry errors.
- A country needs 5 listed companies for a row, and 5 published rates before a median rate is shown.
What will your budget reach?
Move the slider. Every figure below is a count of companies whose published minimum project budget sits at or under that amount.
240 of 719 companies (33%) take projects at this size.

This says who will engage, not what your scope should cost. A budget that reaches most of the market still buys very different things depending on what you are building.
Who is focused, and who has proved it
Horizontal: how concentrated a company is on LLM development. Vertical: how much checkable evidence stands behind it. 60 of 1179 companies are plotted — the rest have fewer than 2 evidence signals, so placing them would be guesswork.

How a company is placed
- Focus is the inverse of how many categories a company claims, blended with the share of its portfolio tagged with this one. A firm listing three technologies is concentrated; a firm listing forty also appears here.
- Proven delivery adds published reviews (to 20), portfolio projects (to 25), Ahrefs Domain Rating (to 60) and years listed (to 10). Each is capped so no single signal carries a company to the top.
- Positions are relative to the other companies on this page: the median company sits at the centre of each axis, so a quadrant boundary means "ahead of half the companies listed here". Raw scores are in each bubble's tooltip.
- Deliberately excluded: the star rating, which sits in too narrow a band to separate anyone; the editorial rank, which is a hand-assigned sort weight; and paid verification, which does not move anything on this chart.
- Leaders:
- Concentrated on this work and with the record to show for it.
- Specialists:
- This is most of what they do, but the public evidence is still thin.
- Established generalists:
- A substantial track record, spread across many categories.
- Emerging:
- Building both focus and evidence.

What an LLM engagement covers
Most LLM work is retrieval, evaluation and serving rather than training. A typical engagement takes a corpus you already own, makes it searchable, wires a model over it, and then spends most of its time proving the answers are good enough to rely on.
- Retrieval (RAG). Chunking, embeddings, hybrid search, re-ranking and citation — the difference between a demo and a system people trust.
- Fine-tuning and adapters. LoRA and full fine-tunes for tone, format and narrow tasks, plus distillation to cut cost and latency once behaviour is stable.
- Evaluation. Golden sets, LLM-as-judge scoring, regression suites in CI and human review loops.
- Serving. Self-hosted inference with vLLM or TensorRT, model routing, caching, quantisation and autoscaling.
- Safety. Prompt-injection defences, PII redaction, output filtering and audit logging.
What to ask an LLM vendor
- How do you measure answer quality, and can I see the evaluation set?
- What is the cost per thousand queries at my volume, and what brings it down?
- How do you defend against prompt injection when the model reads untrusted documents?
- Can this run entirely inside my cloud account or on-premise, and what does that cost in quality?
- What happens when the provider deprecates the model version we launched on?
