* feat(ui): add Interactions API support to playground with streaming
Adds /v1beta/interactions as a selectable endpoint in the UI playground.
Uses SSE streaming (stream=true) and parses content.delta events for real-time output.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(interactions): remove forced gemini provider so all providers work via interactions API
Proxy endpoint was hardcoding custom_llm_provider="gemini" before routing,
preventing non-Gemini models from using the litellm_responses bridge.
Also reverts the UI Gemini-only model filter.

* fix(interactions): fix streaming for non-gemini providers via bridge
Two bugs in LiteLLMResponsesInteractionsStreamingIterator:
1. content.delta was emitted without "type":"text" in delta dict, so the
UI type-check always failed and no tokens were displayed
2. First OutputTextDeltaEvent was silently dropped (used to emit content.start
with empty text); fixed by handling ResponsePartAddedEvent for content.start
so text deltas go directly to content.delta

* test(interactions): remove tautological gemini-provider assertion
The test_no_forced_gemini_provider_in_request_data check only asserted
against dict literals it had just constructed, so it always passed and
did not exercise the create_interaction endpoint. The endpoint
deliberately defaults custom_llm_provider to gemini, so the assertion
was also factually incorrect. Drop the misleading test.

* fix(interactions): use ContentPartAddedEvent and guard interaction.start ordering
- ResponsePartAddedEvent corresponds to reasoning summary parts, not text
content parts. Use ContentPartAddedEvent which is the event emitted before
text output deltas (type response.content_part.added).
- Mirror the OutputTextDeltaEvent ordering guard: if interaction.start has
not been sent yet, emit it first before content.start to honor the
documented event ordering contract.

* test(interactions): cover ContentPartAddedEvent ordering and no-op paths
* fix(tests): treat corrupt VCR cassette payloads as cache miss + use gpt-realtime in OpenAI realtime guardrails test
VCR redis persister was raising UnicodeDecodeError on cached payloads that
fail to UTF-8 decode (e.g. legacy entries written by another version of
the persister), failing tests at fixture setup instead of degrading to a
cache miss. Wrap decode+deserialize in a try/except so corrupt cache
entries are treated as CassetteNotFoundError, surfacing the failure via
the existing _record_cache_failure / VCRCassetteCacheWarning path.
OpenAI shut down gpt-4o-realtime-preview-2024-12-17 (and the entire
gpt-4o-realtime-preview family) on 2026-05-07. The live realtime
guardrails integration test now fails with model_not_found instead of
receiving session.created. Point OPENAI_REALTIME_URL at the current GA
model gpt-realtime, and relax the assertion in
test_text_message_blocked_by_guardrail_no_ai_response to also accept the
model's refusal-to-repeat the block message (gpt-realtime declines
verbatim-repeat instructions, which is still a safe outcome since the
original user message was blocked before reaching OpenAI). The
BLOCKED_PHRASE leak check is preserved as a hard invariant.
* fix(tests): migrate realtime + nvidia_nim rerank tests off shut-down upstream models
OpenAI shut down the entire gpt-4o-realtime-preview family (including the
undated alias) on 2026-05-07. The live realtime tests still connected
with that dead alias and failed with messages_received=1 (an error event
'The model gpt-4o-realtime-preview does not exist' instead of
session.created). Point the live OpenAI realtime tests at gpt-realtime,
the current GA realtime model:
- test_openai_realtime_simple.py: get_model() -> gpt-realtime
- test_openai_realtime.py: test_openai_realtime_direct_call_no_intent and
test_openai_realtime_direct_call_with_intent -> openai/gpt-realtime
Mocked unit tests (test_realtime_query_params_construction,
test_realtime_query_params_use_normalized_model_name) are left as-is:
they never hit the network and assert string plumbing only.
NVIDIA reached end-of-life for the hosted
nvidia/llama-3.2-nv-rerankqa-1b-v2 rerank API on 2026-05-18 with no
published replacement, so the live BaseLLMRerankTest.test_basic_rerank
for nvidia_nim now returns HTTP 410 ('Gone'). NVIDIA's hosted catalog
rotates on a schedule, so swapping in another live model would only
defer the failure. Override test_basic_rerank in TestNvidiaNim to mock
the sync/async HTTP transport (same pattern as
test_nvidia_nim_rerank_ranking_endpoint in this file) and inject a fake
NVIDIA_NIM_API_KEY via monkeypatch. The request/response transformation
and cost calculation stay covered offline.
* test(callbacks): harden flaky proxy callback-leak detector
The proxy callback-leak detector (test_check_num_callbacks_on_lowest_latency)
was failing on this PR with 'abs(85 - 95) <= 4' — a bounded one-time
registration jump caused by switching to latency-based-routing
(+LowestLatencyLoggingHandler, +SlackAlerting). The count then plateaus
under load, so this is pollution from the test's own config update, not a
leak.
Replace the brittle two-sample diff threshold with a sampler that settles
past the deliberate config switch and only flags sustained monotonic
per-type growth, with a terminal-burst confirmation pass for leaks that
would otherwise escape the >=2-interval guard. Normalizes instance
addresses so identical callbacks at different memory locations collapse,
and names the leaking type on failure.
* fix(interactions): preserve first text token when both start events are missing
When OutputTextDeltaEvent arrived before any ResponseCreatedEvent or
ContentPartAddedEvent, the double-fallback path emitted interaction.start
and silently dropped the first delta's text — the second delta's
content.start carried only that chunk's delta, and the first token never
made it to any content.delta event consumed by the UI.
Queue a content.start that carries the first delta's text alongside the
interaction.start emission, and drain pending events before pulling the
next upstream chunk.
* chore(ui): remove unused InteractionOutput/InteractionResponse interfaces

Testing for litellm/
This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.
The point of this is to:
- Increase test coverage of
litellm/ - Make it easy for contributors to add tests for the
litellm/package and easily run tests without needing LLM API keys.
