Claude Platform 101

Ninety minutes covering the Developer Platform — the API, the Console, and how building on Claude differs from using it.

Take this before the big one

Building with the Claude API is 67 lessons and nine hours. Platform 101 is the ninety-minute version that tells you whether you want to commit to that.

The two things a course cannot keep current

Whatever the course says, verify these against the docs before you ship:

• Deprecated parameters. temperature, top_p and top_k return a 400 error on Claude Opus 4.7 and later. Course material written before that will show them.
• Thinking. thinking.type: "enabled" does not exist on any Claude 5 model; those use adaptive thinking instead. Haiku 4.5 is the reverse.

Both are the kind of change that breaks working code silently — see model deprecations.
