🎯 WHAT CHANGED

Podcast Models (Migration 18)

Before (BROKEN & PAID):

  • Outline: openai/gpt-5-mini ← Model doesn't exist!
  • Transcript: openai/gpt-5-mini ← Model doesn't exist!
  • TTS: openai/gpt-4o-mini-tts ← Model doesn't exist!
  • Cost: Would fail + $15-30/month if fixed

After (FREE & WORKING):

  • Outline: groq/llama-3.1-8b-instant ← Fast, FREE
  • Transcript: groq/llama-3.1-70b-versatile ← Smart, FREE
  • TTS: google/gemini-1.5-flash ← FREE
  • Cost: $0/month!

📊 FREE TIER LIMITS

Provider Free Limit Good For
Groq 30 req/min
~7000 req/day		 Chat, Transformations, Podcasts
Gemini 60 req/min
1500 req/day		 Embeddings, Long Context, TTS
Railway $5 credit/month Hosting (costs $5-10/month)

Total Cost: ~$5-10/month (just hosting!)

✅ Verification

After deploy, check logs for:

Migrations completed successfully. Database is now at version 18

Then test:

  • ✅ Chat works with Groq
  • ✅ Search works with Gemini embeddings
  • ✅ Podcasts work with Groq + Gemini TTS

🆘 If It Fails

"Migration 18 not found"

→ Make sure you committed migrations/18.surrealql

"GROQ_API_KEY not set"

→ Get free key: https://console.groq.com/keys

"GOOGLE_API_KEY not set"

→ Get free key: https://makersuite.google.com/app/apikey

"Model not found"

→ Migration 18 probably didn't run. Check logs.
