Adds support for extended cache retention via PI_CACHE_RETENTION=long:
- Anthropic: 5m -> 1h TTL
- OpenAI: in-memory -> 24h retention
Only applies to direct API calls (api.anthropic.com, api.openai.com).
Proxies and other providers are unaffected.
fixes#967
- Handle pipe-separated IDs from OpenAI Responses API in openai-completions provider
- Strip trailing underscores after truncation in openai-responses-shared (OpenAI Codex rejects them)
- Add regression tests for tool call ID normalization
fixes#1022
429 (Too Many Requests) was incorrectly classified as context overflow,
triggering compaction instead of retry with backoff. The original logic
assumed token-based rate limiting correlates with context overflow, but
these are different concepts:
- Rate limiting (429): requests/tokens per time period (throughput)
- Context overflow: single request exceeds context window (size)
Now 429 errors are handled by the existing retry logic with exponential
backoff, while 400/413 remain as potential context overflow indicators.
fixes#1038
Proxies like Portkey omit input_tokens in message_delta events (it's nullable
per the SDK). The previous code unconditionally overwrote usage fields, causing
input token counts to reset to 0.
Now only updates usage fields when they are present (not null), preserving
the correct input_tokens value captured from message_start.
Fixes#1045
Add status === 'deprecated' check for OpenCode Zen models, matching
the existing pattern used for GitHub Copilot models. This removes
deprecated models like glm-4.7-free and minimax-m2.1-free from the
generated model catalog.
Allows custom models to specify which upstream providers OpenRouter
should route requests to via the `openRouterRouting` field in model
definitions.
Supported fields:
- `only`: list of provider slugs to exclusively use
- `order`: list of provider slugs to try in order
When Google providers return tool calls without an args field (common for
no-argument tools), the arguments field was undefined. This breaks
subsequent API calls that require tool_use.input to be present.
Now defaults to {} when args is missing.

fix bug encountered when running GLM-4.7-Flash hosted by LM Studio, in
which the provider sends tool call arguments via
`response.function_call_arguments.done` events instead of streaming them
via `response.function_call_arguments.delta` events. The final
`response.output_item.done` event then contains empty `{}` arguments.
The code only handled delta events, so tool calls failed with validation
errors like `"must have required property 'command'"`.
Full disclosure, Opus triaged the bug and provided the fix (by adding
logging statements to the req/resp to the upstream provider (LM
Studio)). I'm to provide prompts/transcripts, and acknowledge that I'm
not an expert in Pi internals at this time.
When switching between OpenAI models (e.g., gpt-5-mini to gpt-5.2-codex),
function_call IDs with fc_ prefix trigger pairing validation errors because
OpenAI tracks which fc_xxx IDs were paired with rs_xxx reasoning items.
The fix omits the id field for function_calls from different models, which
avoids the pairing validation while keeping call_id for matching with
function_call_output.
Fixes#886
- Added headers field to base StreamOptions interface
- Updated all providers to merge options.headers with defaults
- Forward headers and onPayload through streamSimple/completeSimple
- Bedrock not supported (uses AWS SDK auth)
