DAVID
Every transaction makes you smarter than your Goliath competitors.
DAVID is a 5-layer AI pipeline stack: Sesh (gateway) → 626 (orchestration) → Stitch (intelligence) → Tinker (fine-tuning). Named after Disney's Lilo & Stitch. Every layer is a character. Together, they form a self-improving intelligence engine that compounds with every interaction.
What it does
How it works
Request enters through Sesh
API gateway authenticates, rate-limits, and routes the request. Cost is pre-estimated and budget-checked before any tokens are spent.
Stitch selects the optimal model
ModelRouter analyzes the task (chat? code? SQL?), scores 14 models by complexity and cost, and picks the best candidate with 3 fallbacks.
626 orchestrates the workflow
Temporal workflows manage the full lifecycle: context fitting → prompt resolution → generation → tool execution → quality evaluation. Durable and retryable.
Quality gate validates the response
QualityGate scores the output. If it fails: SelfRefineLoop retries with feedback. Only responses that pass quality thresholds reach the user.
Tinker closes the learning loop
Langfuse traces + user feedback → training data. Dagster orchestrates batch fine-tuning via TML. The next response is better because of this one.
