Five reviewers (Fable 5.1, Opus 5.5, Sonnet 5.5, Codex GPT-6 Astra, Codex
GPT-6.1 Sol) found no behavior or security regression; this commit applies
what they asked for.
Settings dialog: the automatic model list fetch only fills the list, which
waits behind 'Browse models'; it no longer opens the picker (the modal picker
took the focus from whatever the user was typing) and shows no error of its
own. One list request per provider at a time, so a click during the automatic
fetch sends nothing twice; the baseline that detects freshly entered
credentials is taken on every visit of a provider page; SGLang's prefilled
local example URL triggers no fetch. Entries saved with Azure's old
placeholder URL still count as having no URL. The base URL field of Azure and
of the custom preset is labelled required (new dictionary key baseUrlRequired).
Smaller code: the PROVIDER_INFO alias is gone (three files and the tests
import PROVIDERS), as are three logo values no code read, two unused type
re-exports, three unused exports and SINGLE_SYSTEM_PROVIDERS (the chat route
reads the record). Renamed for clarity: REQUIRED_KEY_VARS, requiredKeyEnv,
configuredUrl, LocalizedText. Seven stale comments rewritten; the custom
preset's note shortened.
Tests: the matrix gains six override shapes (a Vertex key alone, AWS keys with
a session token, headers with a URL, a trusted URL with a key, a key with a
server model's URL variable, '/' alone), 5843 rows; the new rows were
regenerated on the pre-refactor code and match it. The matrix and the server
credential tests clear every variable they read; the admin variable table
covers every provider; a test that derived its expectation from the function
under test is gone; the singleSystem, listNeedsNoKey, sdkKnowsEndpoint and
auto-detection sets are spelled out.
Docs: the READMEs say 25 providers and name the OpenAI-compatible preset; the
AI_PROVIDER lists are complete; the Azure example URL has its /openai suffix;
'Adding a Provider' names the tests to update.
Step 8 of the provider refactor plan, a new provider made of one record.
'custom' runs on @ai-sdk/openai-compatible with <think> extraction, merges
system messages (open-source chat templates reject several), has no default
URL (so a key alone does not count as connected, and the chat endpoint is
shown under the URL field) and lists models from its /models. Server side:
CUSTOM_API_KEY and CUSTOM_BASE_URL, ADMIN_CUSTOM_* in the admin panel.
env.example and the three provider docs gained a section; the picker count
in the e2e test is 25 and a new e2e test walks through the preset. The
behavior snapshot gained the new provider's 146 rows; its two 'No AI provider
configured' rows list CUSTOM_API_KEY now.
Step 5 of the provider refactor plan. Provider names gave way to the
record's credential and sdk fields in: hasCredentials (one rule per
credential kind), the connection test (an Object.hasOwn check first, then a
credential switch; EdgeOne's site endpoint and cookie forwarding follow
credential none), the chat route (the on-site function and the single-system
rule for the OpenAI SDK), the credentials form (which fields to show, the
optional-key label, the base URL hint from the record), the picker (the note
from the record), the logo (icon and logo fields), the settings dialog (test
blocker, error hints, EdgeOne origin), the admin panel (fixedCredentials),
chatRequestUrl (sdk), the model list (sdk aihubmix) and the zod schema
(Object.hasOwn instead of 'in'). The eight provider-specific dictionary
entries moved into the record as four-language objects; needAzure became a
generic needUrl.
Two intended behavior changes: the connection test answers 400 'Invalid
provider' for an unknown name whether or not a key is sent (before: 400
'API key is required' without a key, 200 with an error text with one); and
Azure has no placeholder default URL any more, so a new Azure entry starts
with an empty URL and the generic 'needs a URL' rule applies. The e2e
Azure test seeds no URL and expects the new wording. Out-of-layer
provider-name checks: 44 before, 6 after (the admin panel's fixed-variable
branches for Bedrock, Vertex AI and Ollama, kept on purpose). Behavior
snapshot unchanged.
Step 2 of the provider refactor plan. lib/providers.ts holds one record per
provider (SDK kind, credential kind, env prefix, default URL, picker group,
notes and base URL hints in four languages, and the short model list of the
six providers that cannot list models). ProviderName is now the record's
key set and lib/types/model-config.ts re-exports the record as PROVIDER_INFO,
so the twelve importers are unchanged.
Derived from the record, under their old names and in their old files:
FIXED_CRED_PROVIDERS, PROVIDER_LOGO_MAP and chatRequestUrl's own-path list
(model-config.ts), SINGLE_SYSTEM_PROVIDERS, PROVIDER_ENV_VARS and
SDK_KNOWS_ENDPOINT (ai-providers.ts), PROVIDER_GROUPS and OPTIONS_OPEN
(provider-setup.ts), NO_KEY_NEEDED (provider-models route).
tests/unit/providers.test.ts freezes the old tables' values and checks the
derived ones against them. The record is written in the picker's order, so
the provider lists in two 'No AI provider configured' messages change order;
those two snapshot rows are the only snapshot change.
