Очень рада что решила довериться ребятам. Команда работает системно, прозрачно и на результат. Рекомендую как надежного исполнителя.
MOSKVA PRODUCTION
Благодарим команду креативного агентства ООО «МЕДИА ПРОДАКШН ГРУПП» (MOSKVA PRODUCTION) в лице Директора Христенко Кирилла Игоревича за помощь с реализацией проекта по созданию корпоративных видеороликов для нашей компании. Особенно хочется отметить высокий профессионализм команды по всей цепочке создания видеопродукта: начиная с этапа планирования и написания сценария, реализации съемочного процесса и заканчивая финальным этапом монтажа и внесения правок и корректировок по нашей просьбе. Желаем новых творческих проектов, экономического процветания и надеемся на дальнейшее сотрудничество!
Web Chemists
Заказывали у Web-Химиков работы по сайту и дальнейшей оптимизации. До этого уже был опыт с другими исполнителями, поэтому подход сравнить есть с чем. Здесь понравилась организованность: сначала собрали информацию, уточнили цели, потом предложили понятный план действий. В процессе не пропадали, держали связь и нормально реагировали на замечания. Отдельно отмечу, что не было ощущения, будто тебе просто продают услугу — чувствовалось, что люди реально погружены в проект. По итогу сайт стал удобнее, а по продвижению начали появляться заметные сдвиги. Впечатление положительное, работать было комфортно.
What an AI agent team actually builds
An agent is a model given tools, memory and a loop: it decides what to do next, calls an API or a script, reads the result, and repeats until the task is done or a limit is hit. The interesting engineering is not the prompt — it is what happens when a tool call fails, when the model loops, or when it confidently does the wrong thing.
- Tool and API layers. Typed, well-described functions the model can call, with validation, retries and idempotency so a repeated call cannot double-charge a customer.
- Orchestration. Planner-executor patterns, multi-agent hand-offs, and state that survives a crash mid-run.
- Human-in-the-loop controls. Approval gates on anything irreversible — payments, emails to customers, database writes.
- Evaluation and traces. Recorded runs, replayable failures and a scored test set, so behaviour can be compared release to release.
- Cost and latency budgets. Step caps, model routing and caching, because an unbounded agent loop is an unbounded invoice.
How to choose an agent development vendor
- Ask to see a trace of a real production run, including a failure and how the system recovered.
- Ask what percentage of runs complete without human intervention, and how that number is measured.
- Check the guardrails: step limits, spend limits, permission scopes and rollback for every tool with side effects.
- Confirm the framework choice is a decision, not a habit — and that you can maintain what they leave behind.
- Start with one workflow that has a clear success signal. Agents that own a single process outperform general-purpose assistants in nearly every deployment.
