* fix(ai): send max_tokens for Z.AI providers
Z.AI (zai, zai-coding-cn, api.z.ai, open.bigmodel.cn) ignores
max_completion_tokens and only honors max_tokens, so the configured
output cap never applied and Z.AI fell back to its 65536 default.
Add isZai to detectCompat's useMaxTokens condition.
* fix(ai): set zai max_tokens compat in model generator
Per review feedback: the model generator now maps Z.AI to max_tokens, so
regenerated Z.AI model entries carry compat.maxTokensField="max_tokens"
(Z.AI ignores max_completion_tokens). The runtime detectCompat change is
kept as a fallback for custom/self-hosted Z.AI base URLs not in the catalog,
matching how moonshot/together/nvidia are handled in both places.
Route claude-opus-5 through the Anthropic Messages API with adaptive
thinking, the Copilot minimal thinking-level override, and pin the
extended 1M context window alongside the other Copilot Opus models.
Add the constrained sampling API and provider plumbing for OpenAI and Anthropic tool calls, including grammar sampling variants and model capability metadata.
Fresh package installs could give bundled model catalog
files newer filesystem mtimes than the remote catalog’s Last-Modified timestamp,
causing Pi to ignore newer remote models.
Use the catalog’s recorded generation time instead of installation-dependent file metadata.
Treat the models.dev k2p7 entry as an alias for kimi-for-coding and regenerate provider catalogs. This restores consistency between generated model types and values and unblocks repository type checks.
Add Alibaba Cloud Model Studio Token Plan subscription service as two
built-in API-key providers: qwen-token-plan (international, Singapore)
and qwen-token-plan-cn (China, Beijing).
Each provider exposes 15 text-generation models (Qwen, DeepSeek, GLM,
Kimi, MiniMax) via the OpenAI-compatible endpoint with DashScope
enable_thinking support. Model metadata is sourced from models.dev;
qwen3.8-max-preview is hardcoded until models.dev includes it.
Also fixes kimi-coding test references (k2p7 -> kimi-for-coding) after
models.dev catalog update picked up by generate-models.
Closes#6850
mai-code-1-flash-picker is not accessible via /chat/completions and
must use the Copilot /responses endpoint. Update generate-models.ts to
send mai-* models to the responses API and regenerate the affected
model entry.
This adds cache-friendly dynamic tool loading anchored to tool results. Purely additive active-tool changes are recorded with `addedToolNames`, allowing supported Anthropic and OpenAI Responses models to load tool definitions at the point they become available instead of placing them in the cached prompt prefix.
It retains safe fallback behavior for unsupported models and non-additive changes but it will wipe caches.
Updates GitHub Copilot built-in model metadata so models with GitHub's extended 1M capability use contextWindow 1000000 in Pi, preventing early compaction and under-budgeting for Claude Opus 4.7/4.8 and GPT-5.3 Codex/5.4/5.5.
Verified against raw docs markdown extended-capabilities table and live /models reports.
closes#6439
Use the new provider-specific Xiaomi Token Plan catalogs from models.dev instead of cloning the API-billing Xiaomi catalog into every token-plan region. This removes API-billing-only models such as mimo-v2-omni from xiaomi-token-plan-{cn,ams,sgp}.
Broaden the Fireworks GLM 5.2 special-case in generate-models.ts from
an exact id match to a glm-5p2 substring match, so the router variant
accounts/fireworks/routers/glm-5p2-fast also uses the OpenAI-compatible
endpoint and thinkingLevelMap instead of falling back to the default
Anthropic Messages config.
