Claude, the reference model for reasoning and safety

Claude is Anthropic's flagship model, specialized in long reasoning, instruction fidelity and reinforced safety. Its extended context window (200k tokens) and tool use capabilities make it a top-tier choice for complex business cases.

At Inprogress, we use Claude on projects that demand analytical depth, code quality and reliable business assistants. We master the MCP protocol that lets Claude access your tools and data in a secure, standardized way.

The benefits of Claude API

01

Long reasoning and extended context

200k token context window to process entire documents, long conversations and complex tasks without losing coherence.

02

Safety reinforced by design

Constitutional AI and native guardrails: Claude refuses harmful requests and produces more reliable answers for sensitive B2B use cases.

03

Tool use and MCP protocol

Claude calls your APIs, queries your databases, acts on your systems via MCP. Ideal to build agents that manipulate real business tools.

Why Inprogress?

Prioritization

We help you decide quickly what should be built now and what should wait.

Quality

We enforce technical quality to prevent slowdowns and avoid product debt.

Speed

A product should move continuously, with a delivery rhythm the whole team can trust.

Frequently asked questions

We start with a fast audit of product context, codebase and business priorities.

Then we run a shared backlog with short iterations and frequent deliveries.

Yes. We audit the current stack, fix critical issues and restore delivery flow.

The objective is to stabilize quickly without freezing your roadmap.

Yes. We act as an extension of your team with transparent technical steering.

Decisions, backlog and rituals are shared end to end.

Claude excels at long reasoning, document analysis, code and cases where safety matters. GPT remains stronger on audio/vision multimodality and tooling ecosystem.

We pick based on the specific use case, and often design hybrid architectures that leverage both.

MCP (Model Context Protocol) is an open standard created by Anthropic to connect LLMs to external tools in a secure, standardized way.

It simplifies building agents that access your APIs, databases and business tools without reinventing the integration every time.

We pick the right model per task (Claude Haiku for simple, Sonnet for daily, Opus for complex), use prompt caching and monitor costs in production.

A smart model/quality trade-off often divides the bill by 3 or 4 with no noticeable quality loss.
