From 1c30e3c472e8cf3616bbb291c709df0f87f71654 Mon Sep 17 00:00:00 2001 From: Mega Mind <146339422+M3gA-Mind@users.noreply.github.com> Date: Thu, 21 May 2026 03:14:02 +0530 Subject: [PATCH] fix(providers): fall back to reasoning-v1 for unrecognized default_model MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary - Guards against stale `default_model` values (e.g. `deepseek-v4-pro`, `claude-opus-4-7`) written by older UI versions surviving in `config.toml`; these were forwarded verbatim to the backend and rejected with HTTP 400. - Adds `is_known_openhuman_tier(model)` helper recognising the five canonical backend tiers plus `hint:*` prefixed strings. - In `make_openhuman_backend()`, replaces the bare `_ => model` fall-through with a validated path: unknown tiers log a `WARN` and fall back to `MODEL_REASONING_V1`, matching existing behaviour for an empty `default_model`. - Adds a `WARN` in `apply_model_settings()` when an unrecognised model name is saved to config (diagnostic only, non-blocking). ## Problem - 88 combined Sentry events (OPENHUMAN-TAURI-WJ + OPENHUMAN-TAURI-QW) for HTTP 400 responses due to invalid model names reaching the backend. - `config.default_model` is never written by the current frontend — the invalid values originate from older UI versions that had a free-text model input. They persist through app updates and the new UI never clears them. - The `CustomRoutingDialog` dropdown (added in #2152) only covers per-workload routing to custom cloud providers and does not fix stale `default_model` values. ## Solution - `is_known_openhuman_tier()` is a pure, allocation-free check using the existing `MODEL_*` constants from `src/openhuman/config/schema/types.rs`. - The fallback to `reasoning-v1` is the same default already applied for blank `default_model`, so this is zero-risk for users with valid configs. - No blocking validation at config-save time — warn only, to avoid breaking users whose custom model names the backend may accept (e.g. a future tier added before the client updates). ## Submission Checklist > If a section does not apply to this change, mark the item as `N/A` with a one-line reason. Do not delete items. - [x] Tests added or updated (happy path + at least one failure / edge case) per [Testing Strategy](../gitbooks/developing/testing-strategy.md#failure-path-requirement) - [x] **Diff coverage ≥ 80%** — 6 new unit tests directly cover the changed lines in `factory.rs` and the helper; `config/ops.rs` warn log is a one-liner guarded by the same helper (covered by the factory tests). - [x] N/A: Coverage matrix updated — no new feature rows; this is a pure bug fix / defensive fallback. - [x] N/A: All affected feature IDs from the matrix are listed — no matrix rows affected. - [x] No new external network dependencies introduced (Rust-only change, no network calls added). - [x] N/A: Manual smoke checklist — no release-cut surface changes. - [x] Linked issue closed via `Closes #NNN` in the `## Related` section. ## Impact - **Desktop only** (Rust core change). No frontend changes. - Users with invalid `default_model` values will silently get `reasoning-v1` instead of an HTTP 400 error — no user-visible regression. - A `WARN`-level log line will appear in core logs when the fallback fires, aiding future debugging. ## Related Closes #2202 --- ## AI Authored PR Metadata (required for Codex/Linear PRs) > Keep this section for AI-authored PRs.

All pre-existing warnings; zero frontend files changed in this PR. ### Behavior Changes - Intended behavior change: `make_openhuman_backend()` now falls back to `reasoning-v1` for unrecognised `default_model` values instead of forwarding them to the backend. - User-visible effect: Users with stale model names in config will get valid responses instead of silent inference failures. ### Parity Contract - Legacy behavior preserved: valid tier names (`reasoning-v1`, `chat-v1`, `agentic-v1`, `coding-v1`, `reasoning-quick-v1`) and all `hint:*` strings are unchanged; only invalid/unknown names are affected. - Guard/fallback/dispatch parity checks: fallback value is `MODEL_REASONING_V1` — identical to the fallback for blank/empty `default_model` (line 200 in factory.rs before this patch). ### Duplicate / Superseded PR Handling - Duplicate PR(s): N/A - Canonical PR: this PR - Resolution: N/A ## Summary by CodeRabbit * **Bug Fixes** * Better model configuration handling: stored model values are trimmed, supported backend tiers and canonical hint forms are recognized, unrecognized tiers trigger a warning, and invalid default models now fall back to the platform default at inference time. * **Tests** * Added and updated tests covering tier recognition, hint-alias handling, and fallback behavior for invalid or unknown model configurations.
