Services

Our LLM integration services

Not promises. Results.

Model selection and benchmarking

We evaluate o3, Claude Sonnet 4, Mistral, Llama 4, and domain-specific models against your actual use case to find the best balance of quality, speed, and cost.

Fine-tuning and model adaptation

For specialized domains where base models fall short, we design fine-tuning datasets and manage the training pipeline to adapt models to your specific vocabulary and tasks.

Prompt engineering and optimization

We design, test, and iterate on prompts systematically, with evaluation datasets and metrics, so LLM outputs are accurate, consistent, and aligned with your use case.

LLM-powered feature development

We integrate large language models into your existing product, text generation, classification, summarization, extraction, as reliable, user-facing features, not experiments.

Objective

Why build with LLMs?

1

Human-level language understanding

LLMs understand nuance, context, and intent in a way that rule-based NLP cannot. This enables genuinely useful features, assistants that understand your users, not just match keywords.

2

Broad capability with a single API

A single LLM can summarize, classify, extract, translate, generate, and reason, capabilities that previously required separate specialized models or manual processes.

3

Rapid capability delivery

LLM-powered features can be prototyped in days. The iteration cycle from idea to working demo is dramatically compressed compared to training traditional ML models.

4

Continuously improving models

o3, Claude Sonnet 4, and Mistral models improve with each release. Applications built on these APIs benefit automatically from model improvements without retraining.

Services

Why trust us with your project?

Multi-provider expertise

We have production experience with OpenAI, Anthropic, Mistral, Cohere, and open-source Llama models, we choose the right model for your use case, not the one we know best.

Evaluation-first methodology

We define quality metrics and build test sets before writing a single prompt. LLM development without evaluation is guesswork, we treat it as engineering.

Reliability and guardrails

We implement output validation, safety filters, fallback logic, and cost caps so your LLM feature behaves predictably and safely under real production load.

User experience focus

We design LLM features from the user's perspective, streaming responses, loading states, error handling, and feedback mechanisms that make AI features feel polished, not experimental.

Method

Our process with LLMs

Not promises. Results.

1

Use case analysis and model selection

We define the task precisely, identify the right model family, and design an evaluation methodology to measure success before writing any code.

2

Prompt design and baseline evaluation

We develop and test prompts against a representative dataset, establishing a quality baseline that guides all subsequent improvements.

3

Integration and hardening

We integrate the LLM into your product with proper API abstraction, error handling, cost monitoring, and output validation.

4

Production launch and feedback loop

We deploy with observability tooling and establish a process for capturing user feedback and continuously improving prompt and model performance.

FAQ

FAQ: Your questions about LLMs

It depends on your task, latency requirements, and budget. o3 and Claude Sonnet 4 lead on complex reasoning. Mistral and Llama 4 offer excellent cost-performance for simpler tasks. We benchmark against your actual use case before recommending.
