Who is this for?
02
Agencies
Offer AI services under your own name. White-label models and managed inference, delivered as a finished system.
03
Enterprise
Private intelligence with full compliance, data sovereignty, and exportable weights. Your infrastructure, your rules.
The timing
Why now?
The AI landscape has shifted. Custom models are no longer a luxury — they're a strategic necessity.
Headline ratio
10×
Cost reduction in training frontier-grade models, every 18 months. The economics now favour ownership over rental.
Before
Generic GPT workflow
- //$0.03–$0.12 per 1K tokens
- //Data sent to third-party servers
- //Generic responses, no domain expertise
- //Rate limits & API dependency
After
Custom model workflow
- //Fixed hosting cost, 95% cheaper at scale
- //Your VPC, your data, full privacy
- //Domain-tuned expertise and tone
- //No limits, full control
Foundation
Models we support.
Fine-tune frontier open-source models that rival proprietary alternatives. All weights exportable. All inference yours.

The process
The Foundry pipeline.
From raw data to deployed intelligence — four weeks to your custom model. Complex enterprise projects may run six to eight.
Week 101
Data Forge
Create, clean, or synthesize datasets. Domain distillation from frontier models. RL trajectories, instruction sets, labeled evaluations.
Week 202
Model Crafting
Fine-tune models from 1B to 235B parameters on distributed infrastructure. LoRA Without Regret, full fine-tuning, multi-turn, vision.
Week 303
Evaluation
Benchmarks against TruthfulQA, MMLU, GSM8K, HumanEval. Safety tests, hallucination analysis, real-client evals, regression suites.
Week 404
Deployment
Private APIs, SDKs, exportable weights, white-label apps, monitoring, rate limits, analytics. The whole intelligence layer.
The advantage
Stop paying per token. Own your intelligence layer.
95% cheaper
at scale
For high-volume workloads, custom models eliminate per-token API costs. You own the inference economics.
Private
by default
Your weights, your VPC. Nothing leaves your compliance perimeter. Enterprise-grade privacy without bolt-ons.
Domain
expertise
Tailored tone, terminology, and behaviour. Your model speaks your language and understands your context natively.
Exportable
weights
At the end of the engagement you walk away with the model. No vendor lock-in, no recurring license fees on your own work.

Our edge
Why LeemerLabs?
Not another agency — a full AI lab. We build models, agents, pipelines, infrastructure, and entire platforms.
01
Not another agency — a full AI lab
Most 'AI agencies' wrap OpenAI and call it a day. LeemerLabs is the research arm behind LeemerChat, Warren.wiki, ExamMate, HeyCouncil, and DeepThis — real systems used by real people every day.
02
In the AI game since 2023
We were training models, distilling Qwen, orchestrating multi-model workflows, and building agents before GPT-4o, before Gemini, before the hype cycle.
03
Built our own models
We've fine-tuned Qwen, LLaMA, Gemma, Mistral, and Mixtral. We've built internal bilingual models, distilled production models, and shipped custom Orchestrator → Worker chains inside LeemerChat.
04
1B+ tokens processed
LeemerChat alone has served over a billion tokens to real users. That's a billion tokens of real reasoning, real edge cases, and real scale.
05
Ireland's Official Tinker Partner
We're partnered with Thinking Machines, giving us distributed fine-tuning infrastructure most companies will never touch. Fault-tolerant multi-node training from 7B to 235B.
06
Multi-model orchestration
Leemer Heavy, Leemer Heavy Fast, Leemer Research. Multi-agent pipelines using Qwen, Groq LPU, GPT-5, Claude, Kimi, LLaMA, and DeepSeek — in production.
07
Full-stack AI deployment
Private APIs, white-label chat apps, internal agents, custom embeddings, RAG, on-prem deployment, monitoring, rate-limits, logging, analytics. The whole system, not just the weights.
08
Builders, not consultants
Everything we sell, we use in our own products. We're operating. If we didn't build real things, we wouldn't be here.
09
Open models with ownership
We back open-weights. We support local hosting. At the end of the engagement, you own the model, the weights, and the intelligence layer.
10
Waterford-built, globally scaled
World-class AI, built in Ireland. No Silicon Valley ego, no bloated teams. Pure engineering and delivery.
Battle-tested scale
1,000,000,000+
tokens processed across the ecosystem
LeemerChat alone has served over a billion tokens to real users. That's a billion tokens of model reasoning, real-world edge cases, and everything that breaks and everything that scales. This is operator experience, not theoretical knowledge.
Enterprise-ready
Built for compliance.
Full governance, security, and sovereignty controls for organisations that demand the highest standards.

Powered by Tinker
The infrastructure behind frontier models.
Generally available · Built by Thinking Machines Lab
Tinker compresses an entire AI infrastructure team into an API. We use it because it gives our clients something most agencies simply cannot offer: research-grade distributed training through a clean, reliable pipeline.
Serious scale without the DevOps pain
GPU scheduling, checkpointing, fault tolerance, multi-node training — handled. We focus on data, objectives, and evaluation.
Frontier-class models, open weights
Support for modern LLaMA and Qwen families, including huge MoE models. Train against frontier architectures, keep the weights.
LoRA done right
'LoRA Without Regret' gives practical guidance on ranks, learning rates, and RL behaviour. Full-fine-tune performance at a fraction of the compute.
Built by frontier model veterans
Thinking Machines is staffed by former OpenAI leaders — including co-founder John Schulman — who have shipped frontier-scale systems before.
