About This Course

Build a fully playable web-based RPG powered by OpenAI. You'll start with a complete game engine rooms, characters, combat, pixel art, the whole dungeon and progressively breathe life into it using the OpenAI API. Each exercise adds a new AI capability: a game master that remembers your adventure, NPCs with real personalities, dynamically narrated combat, structured output for reliable state changes, streaming responses, and finally voiced narration with the OpenAI Speech API. By the end you'll have a game you actually want to play, and a solid understanding of how to build multi-turn, multi-persona, multi-modal AI applications.

Dungeon Quest Lab 1 — Game Master and NPC Voices

2h 5m 2 Exercises

Wire up the OpenAI client to a working Flask + vanilla JS dungeon shell. In this first lab you'll build a game master with full conversation memory and the ROOM_CHANGE signal that moves the player between rooms, then give every NPC their own private system prompt and conversation history so the same model becomes Marta the innkeeper, Grimtooth the goblin merchant, and Aldric the wizard.

Summon the Game Master Connect the OpenAI API to power the game master. Build a system prompt that describes the dungeon world, hook up Chat Completions with full conversation history, and parse the GM's response to move the player between rooms. ~40 min
Give the Characters a Voice Bring Marta, Grimtooth, and Aldric to life. Each NPC gets their own system prompt and their own private conversation history — the same model becomes three completely different personalities. ~40 min

Dungeon Quest Lab 2 — Combat and Structured Output

2h 5m 2 Exercises

Pick up where Lab 1 left off — the GM and NPC dialogue are already wired in. In this lab you'll build a real combat loop with stat-based damage + AI-narrated rounds + in-character enemy taunts, then upgrade the GM to JSON-mode structured output so room changes, item finds, and gold drops arrive as reliable structured data instead of regex-parsed prose.

Make Combat Actually Hurt Add narrated combat rounds with enemy taunts. Stats decide who wins — the AI only provides the drama. Make two OpenAI calls per round: one for the narrator, one for the enemy's in-character reaction using their own system prompt. ~40 min
The GM Levels Up — Structured Output Upgrade the game master to return structured JSON. Room changes, item discoveries, and gold finds become reliable data fields instead of text the code has to regex-parse. Discover why structured output is the right tool any time an AI needs to update application state. ~40 min

Dungeon Quest Lab 3 — Streaming and Voice

2h 15m 2 Exercises

Pick up the dungeon from Lab 2 with the GM, NPC dialogue, combat, and structured JSON output already in place. In this final lab you'll stream the GM's narration token-by-token over Server-Sent Events with JSON-aware token forwarding and bounded memory compression, then add voiced narration with the OpenAI Speech (TTS) API mapped per character.

Streaming and the Long Memory Stream the GM's responses token-by-token so they feel alive instead of appearing all at once. Then add automatic history summarization so the dungeon never forgets — even after a long adventure pushes the conversation history well past what the model can hold. ~55 min
Voice the Dungeon — Speech Narration Add OpenAI Speech (TTS) narration so the GM, every NPC, and the enemies in combat each speak in a fitting voice. You'll map characters to voices, generate cached MP3s with `client.audio.speech.create`, and wire up a 🔊 Narrate toggle. ~35 min
