What to Avoid

Avoid: Relying on One Free Tier

Free tiers tighten, expire, or change without notice. Multi-provider stacks survive these changes.

Avoid: Frontier-Only Stacks

Frontier APIs (Claude Opus 4.7, GPT-5.5, Gemini Pro) burn budget fast. Default to cheap volume providers (Cerebras, Groq, DeepSeek).

Avoid: Skipping Founder Credits

The $1K-$350K cloud credit programs are the biggest credits available. Apply early, apply often.

Avoid: No Caching

Prompt caching cuts effective input cost by 60-80% on stable prompts. Enable on every provider that supports it.

Avoid: Ignoring Batch APIs

Anthropic and OpenAI batch APIs are 50% discount for 24-hour async processing. Use for evals and content generation.
