Sonnet Code
Service · Core

Work with senior AI Development engineers.

AI features that ship — not demos that impress in a meeting and break in production.

We build AI into products every week. LLM assistants, retrieval-augmented search, classification pipelines, evaluation harnesses — we know the difference between the part of AI that works and the part that still needs a human in the loop.

Why Sonnet Code for AI Development

The bar we hold ourselves to.

Production ML, not notebooks

Every AI feature we ship has evaluation pipelines, observability, and a rollback plan. Demo quality is not our finish line.

Model-agnostic

OpenAI, Anthropic, Gemini, open-weights — we pick the model that fits the workload and know when to switch.

Honest about limits

We'll tell you when AI isn't the right tool. The worst outcome is an AI feature that makes the product worse.

What we build with AI Development

AI Development work, shipped.

LLM applications

Claude and GPT-powered assistants with proper retrieval, tool use, streaming, and caching. Built to scale, not to demo.

Retrieval & search

Vector search with pgvector, Pinecone, or Weaviate, hybrid BM25+embedding rankers, and evaluation harnesses that catch quality drift.

ML classification

Custom classification and extraction models for document processing, content moderation, and data routing.

Evaluation & ops

LLM eval pipelines, model regression detection, and the observability to know when your AI is quietly degrading.
