up the debounce timer. Invalidate prior requests when either value changes, and
only apply cached or fetched results through setProviderModels when the request
still matches the current identity.

Adds Requesty next to OpenRouter in the LLxprt Code backend. It uses the same mechanism: the UI provider maps to the llxprt openai provider with a custom base URL, and the session sets OPENAI_API_KEY and OPENAI_BASE_URL. - provider union, type guard and provider config (base URL https://router.requesty.ai/v1, default model openai/gpt-4o-mini, key page link) - settings dialog entry with base URL autofill and model fetching from /v1/models/managed, falling back to /v1/models - Rust session env setup and provider mapping, plus a test mirroring the OpenRouter one - provider lists in CLAUDE.md
Track a fetch generation in a ref so a slow response for a previous provider is not shown or cached for the current one, and clear the debounce timer when the provider changes or the dialog unmounts.

Summary
Adds Requesty (https://docs.requesty.ai) as a selectable provider in the LLxprt Code backend, wired exactly like the existing OpenRouter preset. Requesty is an OpenAI compatible gateway with one key across OpenAI, Anthropic, Google, DeepSeek and others, so the UI provider maps to the llxprt
openaiprovider with a custom base URL and the session exportsOPENAI_API_KEYandOPENAI_BASE_URL, the same path OpenRouter already uses.Changes
Frontend (every place
openrouteris registered as an LLxprt provider):frontend/src/types/backend.ts:requestyadded to theLLxprtProviderunion and to theisLLxprtConfigwhitelist.frontend/src/utils/providerConfig.ts:PROVIDER_CONFIGS.requesty(base URLhttps://router.requesty.ai/v1, default modelopenai/gpt-4o-mini, key prefixsk-,supportsModelFetch, key pagehttps://app.requesty.ai/api-keys) and aMODEL_PLACEHOLDERSentry.frontend/src/utils/backendDefaults.ts:llxprtProviderDefaults.requesty.frontend/src/components/common/SettingsDialog.tsx: "Requesty (Multi-provider)" select item, base URL autofill on selection, model placeholder, and the Fetch Models button. The model fetch now keys offsupportsModelFetch(provider)and, for Requesty, callsGET /v1/models/managed(curated list) with a fallback toGET /v1/models. The fetched list state is cleared when the provider changes and the cache key includes the provider so OpenRouter and Requesty lists never mix. 403 is treated as an invalid key alongside 401 (Requesty returns 403 for a bad key). The OpenRouter request itself is unchanged.Backend:
crates/backend/src/session/mod.rs:requestyjoins theopenai | openrouterarm inSessionEnvironment::setup_llxprtand theopenrouter => openaiprovider mapping when building the llxprt command. Addedtest_session_environment_llxprt_requesty_with_base_url, a copy of the OpenRouter test.Docs:
CLAUDE.md: Requesty added to the provider lists and the provider defaults table (one line each, same pattern as OpenRouter).Requesty is not added to any default or automatic selection; the default LLxprt provider stays
anthropic. No new dependencies, no i18n keys needed (provider names in the dialog are literals, like the other providers). Qwen backend defaults that happen to point at OpenRouter were left alone on purpose.How to test
