Service 01 / AI Integration

Wire AI into the product,
not into the slide deck

You already have a site or an internal system and want AI in it,

but nobody on the team has shipped one before.

That's the layer I do: timeouts, hallucinations, cost overruns — the engineering.

Who this is for

Does this sound familiar?

「We want an AI assistant but don't know where to start」

「Customers send dozens of emails a day and we answer each one manually」

「It makes things up. Ask about something we don't cover and it just invents an answer」

「Our API bill went up fivefold last month and nobody knows which calls caused it」

What you get

01A one-page scope document: inputs, outputs, boundaries, failure behaviour — signed off before code
02A working module: front-end, back-end and model calls, deployed to your environment
03Prompt templates and context assembly, commented so you can edit them without me
04Cost controls: request timeout, retry ceiling, token cap, caching, per-user rate limits
05Graceful degradation: rule-based fallback when the model times out or is unavailable
06Logging and monitoring: latency, tokens, cost and failure reason per call, exportable
07A one-hour handover recording: how to change prompts, read logs, adjust budget

What I don't do

Stating the limits saves both sides more time than listing capabilities.

No model training

No fine-tuning, no training runs. I integrate commercial model APIs. If your problem genuinely requires a trained model, I'll tell you that directly.

No 100% accuracy guarantee

Anyone promising that is lying. What's achievable: confidence signalling, cited sources, and an explicit "I don't know" outside scope.

Not a content mill

Integration only. Bulk marketing copy generation isn't what I do — I'll point you elsewhere.

No project without a concrete problem

"We should probably use AI somewhere" — I'll help you find the actual use case first. If there isn't one, I won't take the work.

Timeline and pricing

Starter$1,200Single-turn Q&A, no knowledge base, fixed prompt7–9 working days
Standard$2,200Multi-turn + retrieval + admin-configurable10–12 working days
Full$3,600Multi-scenario + admin panel + dashboard + human handoff12+ working days

Fixed pricing, not hourly. Under $2,200: 50% upfront, 50% on acceptance. Above: three instalments. Third-party costs (server, API, domain) are not included.

Why take my word

Common questions

Which model?

OpenAI-compatible by default — DeepSeek, GPT, Qwen and others all fit. I'll compare them on your budget and latency needs during scoping. Models can be swapped without rewriting the integration.

What will the API bill look like?

Depends on volume and context length. At 100 calls/day with 2,000-token contexts, most models land in the low hundreds of RMB per month. I'll give you a capped plan before you sign.

Is my data used for training?

Commercial APIs generally don't train on your data, though terms differ by provider — I'll confirm for whichever you pick. If the data is sensitive, local or private deployment is possible, at a different price point.

Can I edit it myself after handover?

Yes. Prompts are separate, commented files. Logs are viewable. The handover recording walks through it. Only logic changes need me.

What if it doesn't work well?

Acceptance criteria (accuracy, latency) are set during scoping. If they aren't met, it isn't accepted and the balance isn't paid. Writing the criteria early protects both sides.

Just describe the problem

No requirements document needed. Tell me who does this task now, how slow it is, and where it goes wrong. I'll say whether AI fits and roughly what it costs.

Describe the problem

Other services

Public pricing, written boundaries, and an honest no when it's not a fit. That saves more time than any promise.
