Dassah's Prism · isolated experiment board

Prism capability lab

This board tracks Google, OpenRouter, and future provider capabilities before they touch live Prism. “Benchmark complete” does not mean production approved.

Promotion rule: every capability must prove usefulness, safety, privacy, economics, and product fit on synthetic or public data. A free tier is not automatically private, stable, or unlimited.

Capability map

Capability	Prism use	Stage	Required evidence
Gemini Embedding 2	Multimodal semantic retrieval	Benchmark complete	RLS, deletion, retention, generation injection
Gemini File Search	Managed RAG with citations	Next comparison	Quality, citations, deletion, tenant isolation, cost
Gemini 3.8 Flash	Standard refraction	Next comparison	Quality, structured output, latency, cost
Gemini 4 Argon	Hard reasoning escalation	Planned	Only promote if quality gain justifies cost
URL Context	Public webpage/PDF refraction	Planned	Citations, stale-page notice, injection isolation
Google Search grounding	Current facts with citations	Planned	Explicit verify/current mode only
Gemini TTS	Voice output and mood controls	Planned	Mood quality, latency, audio cost, consent
Gemini Transcribe	Voice notes to tasks	Planned	Consent, timestamps, diarization, retention
Gemini Live	Real-time voice conversation	Deferred	Only after TTS and transcription are reliable
Nano Banana	Optional visual learning cards	Deferred	Must improve comprehension, not distraction
Gemma 4	Privacy/on-device research	Deferred	Separate managed/GPU cost experiment; no vLLM now
OpenRouter / Jev	Provider routing and fallback	Evaluation only	Actual model, cost, provider disclosure, failure handling

Current order

Next: File Search versus Embedding 2, Gemini 3.8 Flash versus the current baseline, then Gemini TTS, URL Context, and Transcribe.

Later: Argon escalation, Search grounding, image generation, Live API, and Gemma 4 managed/on-device research.

Never automatic: no private document in a free-tier experiment, no provider key in browser code, no live feature without a rollback flag, and no document instruction is allowed to override system safety rules.
