GitHub Copilot serves grok-4.6 / grok-4.6-1m only via /responses, but
isCopilotResponsesModelId matched grok-4.5 exactly, so both the static
generator and dynamic discovery classified grok-4.6 as openai-completions
and requests 400d with unsupported_api_for_model.
- match grok-4.6 in isCopilotResponsesModelId
- add grok-4.6 / grok-4.6-1m to COPILOT_CACHE_INVALIDATED_MODEL_IDS so
stale cached completion routes drop on refresh
- regenerate github-copilot/grok-4.6 to api openai-responses (compat
block dropped, xhigh effort added by the responses policy)
- cover discovery routing and cache migration in tests
Fixes#8807
Copilot discovery writes an authoritative cache, so online-if-uncached served the prior endpoint for the full TTL after COPILOT_GITHUB_TOKEN switched accounts. Keying the cache namespace on the credential forces fresh discovery for a new token instead of reusing a stale personal-endpoint cache.
Fixes#8507
Threaded the shared 10s discovery AbortSignal into the copilot_internal/user probe so a stalled endpoint falls back to the personal host instead of hanging startup or refresh.
Fixes#8507
Shared the plan-endpoint probe between OAuth login and raw token model discovery so Business credentials route to their advertised API host.
Added regression coverage for the raw environment-token path.
Fixes#8507
- Remove redundant definedness, null, and type checks across test suites in multiple packages.
- Clean up unused assertions, metadata tests, and obsolete test cases.
- Add good versus bad test filter guidelines and requirements to project documentation.
- The regenerated bundle (merged with PR #8021) now ships a
responses-route github-copilot/grok-4.5, so the id legitimately
resurfaces from the bundle when the migration refresh fails; the
contract worth defending is that the stale cached completions route
never returns and the unbundled long-context variant stays dropped.
Applied GitHub Copilot's discovered default token-price tier to base models while preserving the provider fallback for unreported cache-write costs. Added regression coverage for GPT-5.6 Luna base and long-context pricing.
Fixes#7471
Drop the synthesized grok-4.5-1m completion route alongside its base model during the Copilot Responses migration.
Cover the failed-refresh fallback so neither stale selectable route survives when discovery is unavailable.
Fixes#7096
Fold provider cache-drop policies into the catalog fingerprint and force online-if-uncached discovery when an affected cached model is present.
Seed the Copilot migration regression with the real bundled fingerprint and verify stale Grok and MAI completion routes are rewritten through Responses.
Fixes#7096
Drop cached grok-4.5 Chat Completions rows when the bundled Copilot catalog fingerprint changes, matching the existing MAI endpoint migration.
Cover both cached endpoint migrations through the model manager's default online-if-uncached path.
Fixes#7096
Route the Copilot-discovered grok-4.5 model through the Responses API so requests no longer hit the unsupported Chat Completions endpoint.
Add focused discovery coverage for the endpoint contract.
Fixes#7096
GitHub Copilot's mai-code-1-flash-picker (and other mai-* models) are
served only through the /responses endpoint; the classifier routed them
to /chat/completions, which returned 400 unsupported_api_for_model.
Added the mai- prefix to isCopilotResponsesModelId so both dynamic
discovery (inferCopilotApi) and bundled resolution
(COPILOT_API_RESOLUTION_RULES) select openai-responses, and updated the
bundled models.json entry to match.
Fixes#5612
Treat GitHub Copilot discovery input as authoritative during model merges so explicit supports.vision=false is not OR-upgraded from bundled references.
Fixes#4779
GitHub Copilot's /models response advertises supports.vision = true for
Claude/GPT chat models on every host, but only the canonical personal
endpoint (https://api.githubcopilot.com) actually accepts image inputs;
the business (api.business.githubcopilot.com) and enterprise
(copilot-api.{domain}) hosts respond '400 vision is not supported'.
snapcompact then injected rasterized transcript frames after compaction
and permanently broke every business-Copilot session.
- Catalog discovery (githubCopilotModelManagerOptions.mapModel) now
forces input=['text'] whenever the resolved baseUrl is not the
canonical personal-Copilot host, so the upstream's vision flag is
honoured only where it actually works.
- mergeDynamicModel honours the dynamic input value (instead of
OR-upgrading with the bundled reference) when the merged baseUrl
differs from the bundled one, so a bundled spec pinned to the
personal host can no longer taint a business-resolved merge.
- snapcompact-inline's canSendImages helper short-circuits the
rasterizer for any github-copilot model whose baseUrl is non-personal,
catching stale cached specs that still advertise vision.
- Helper isPersonalGitHubCopilotBaseUrl exported from
pi-catalog/wire/github-copilot so catalog and coding-agent share one
canonical check.
Regression coverage in github-copilot-model-limits.test.ts (vision
endpoint policy + full merge) and snapcompact-inline.test.ts (#3387
business/enterprise case).
Fixes#3387
Stored GitHub Copilot plan-specific API endpoints discovered during OAuth login and propagated them through structured credentials, model discovery, usage/probe metadata, and request base URL resolution.
Added regression coverage for Business endpoint discovery, serialization, dynamic model discovery, and chat/responses routing.
Fixes#2876
- Added optional `requestModelId` to the `Model` interface for upstream wire overrides.
- Prioritized `model.requestModelId` when resolving request model IDs for Anthropic and OpenAI paths.
- Used `COPILOT_API_HEADERS` in Copilot discovery and policy calls with API version `2026-06-01`.
- Synthesized Copilot `-1m` long-context sibling models with dedicated upstream IDs and pricing data.
- Replaced minLevel/maxLevel range with explicit efforts array plus baked effortMap/supportsDisplay wire facts.
- Removed runtime enrichment layer and modelOmitsReasoningEffort; providers now read baked fields.
- Fixed dotted Opus 4.7/4.8 ids missing adaptive display via classifier-based predicates (#1373).
- Bumped model cache schema to v4 to invalidate pre-efforts rows.
Move bundled models, model cache/manager, thinking metadata, effort helpers,
provider descriptors/discovery, wire constants, and model identity utilities
into the new @oh-my-pi/pi-catalog package.
Update pi-ai to keep provider runtime/auth concerns, move catalog provider
metadata into CATALOG_PROVIDERS, and migrate coding-agent, agent, stats, docs,
and tests to import catalog values from pi-catalog.
Split coding-agent model registry helpers into discovery, roles, and models
config modules while preserving registry orchestration.
BREAKING CHANGE: @oh-my-pi/pi-ai no longer exports catalog subpaths such as
/models, /model-cache, /model-manager, /model-thinking, /effort,
/provider-models*, discovery helpers, and provider wire constants; use the
matching @oh-my-pi/pi-catalog subpaths instead.
