docs(model-chain): correct V4 Pro retirement claim; record flash cost-map override

Browse Source 
- V4 Pro is NOT retiring Sep 14: DeepSeek reversed the sunset and continues it unchanged at 1.32/3.96, so the legacy name does not auto-route to Flash
- admin-ai built-in map carried the superseded Flash peak rates (0.44 miss / 0.014 cache-hit / 1.32 out)
- applied peak override via /model/update (0.30 miss / 0.006 cache-hit / 1.20 out)
- verified: persisted in litellm_params, API-reported, live call billed 1.71e-05

# AI Model Architecture — IT Pro Partner

**Updated:** September 11, 2026
Two separate concepts: **fallback chain** (survival — direct API keys) and **operational chain** (daily toolbox — admin-ai only). The two-key strategy means operational keys run through admin-ai/LiteLLM; fallback keys are direct provider API keys with daily limits.

- **Aug 5, 2026:** Admin-ai budget cap hit (~$20). Fallback chain exhausted 4 dead legs, landed on Anthropic direct. Burned $45 in 10 hours on claude-sonnet-5 via direct key. Anthropic key capped until Sep 1.
- **Aug 6, 2026:** Root cause of Aug 5 outage: 4 fallback legs dead simultaneously (admin-ai budget, DeepSeek balance $0, grok-4.6 404, Anthropic capped). Implemented two-key strategy (operational vs fallback). Rotated all 5 fallback keys. Added F5 (gpt-5-mini via OpenAI). Added haiku-4-5 and grok-4.5 to operational chain. Fixed grok-4.6 → grok-4.5. Synced Anita profile identically. Budget raised to $30.
- **Aug 17, 2026:** Live verification of fallback chain against the LiteLLM model DB (admin-ai). Confirmed present: `deepseek-v4-flash`, `gemini-3.6-flash` (registered as `gemini/gemini-3.6-flash`), `grok-4.5` (`xai/grok-4.5`), `claude-sonnet-5`. Replaced F5 `gpt-4.1-mini` → `gpt-5-mini` — the gpt-4.1 series is no longer present in LiteLLM. Synced `config.yaml` `fallback_providers` and `model.fallbacks`.
- **Sep 3, 2026:** DeepSeek promo rates ended and prices rose again. Live LiteLLM map now bills deepseek-v4-pro at $1.32/$3.96 and deepseek-v4-flash at $0.44/$1.32 (peak; off-peak half). Registered gemini-3.8-flash ($0.75/$3.75 intro) on admin-ai. Swapped F2 and Professional Comms gemini-3.6-flash to gemini-3.8-flash (Core + Anita). Restored delegation default to deepseek-v4-pro (was claude-sonnet-5, ~$13/day burn). Corrected F5 name in operational-models.md. Re-baselined cost tracker thresholds ($3/$4 to $15/$20). Verified actual key budgets: hermes-agent-v5 $700/30d ($23.33/day), Anita $100/30d ($3.33/day).
- **Sep 3, 2026 (sonar + vision):** Seated Perplexity sonar as the Research tier (`sonar-pro` + `sonar-reasoning-pro`, both verified search-grounded via admin-ai with live test calls). Swapped `auxiliary.vision` `claude-sonnet-5` → `claude-haiku-4-5` (still `anthropic` direct), ~3x cheaper vision; verified with a real image call. Conductor unchanged (stays `deepseek-v4-pro`).
- **Sep 11, 2026:** DeepSeek V4.1 Flash released (Sep 10) and surpasses V4 Pro on performance/cost/speed. Flipped primary + delegation from deepseek-v4-pro to deepseek-v4-flash on Core and Anita. V4.1 Flash peak $0.30 input / $1.20 output (off-peak $0.15/$0.60; cache-hit peak $0.006). **CORRECTION (verified against the live DeepSeek pricing page, Sep 11): V4 Pro is NOT retiring.** DeepSeek reversed the Sep 14 sunset and continues V4 Pro unchanged at $1.32/$3.96, so the legacy name does not auto-route to Flash. Cost map: the admin-ai built-in map carried the superseded Flash peak ($0.44 miss / $0.014 cache-hit / $1.32 out); a peak override ($0.30 miss / $0.006 cache-hit / $1.20 out) was applied to the `deepseek-v4-flash` deployment via `/model/update` and verified end-to-end (live call billed 1.71e-05 = 37x3e-07 + 5x1.2e-06). Pro in the map was already correct at $1.32/$0.044/$3.96.
