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.
