382e216cbb fix(core): differentiate BYOK vs base provider in all LLM error details (#9425)
Add is_byok flag to every LLMError's details dict returned from
handle_llm_error across all providers (OpenAI, Anthropic, Google,
ChatGPT OAuth). This enables observability into whether errors
originate from Letta's production keys or user-provided BYOK keys.

The rate limit handler in app.py now returns a more helpful message
for BYOK users ("check your provider's rate limits and billing")
versus the generic message for base provider rate limits.

424a1ada64 fix: google gen ai format error fix (#9147)
* google gen ai format error fix

* fix(core): add $ref safety net, warning log, and unit tests for Google schema resolution

- Add `$ref` to unsupported_keys in `_clean_google_ai_schema_properties` so unresolvable refs (e.g. `#/properties/...` style) are stripped as a safety net instead of crashing the Google SDK
- Add warning log when `_resolve_json_schema_refs` encounters a ref it cannot resolve
- Deduplicate the `#/$defs/` and `#/definitions/` resolution branches
- Add 11 unit tests covering: single/multiple $defs, nested refs, refs in anyOf/allOf, array items, definitions key, unresolvable refs, and the full resolve+clean pipeline

23c94ec6d3 feat: add log probabilities from OpenAI-compatible servers and SGLang native endpoint (#9240)
* Add log probabilities support for RL training

This enables Letta server to request and return log probabilities from
OpenAI-compatible providers (including SGLang) for use in RL training.

Changes:
- LLMConfig: Add return_logprobs and top_logprobs fields
- OpenAIClient: Set logprobs in ChatCompletionRequest when enabled
- LettaLLMAdapter: Add logprobs field and extract from response
- LettaResponse: Add logprobs field to return log probs to client
- LettaRequest: Add return_logprobs/top_logprobs for per-request override
- LettaAgentV3: Store and pass logprobs through to response
- agents.py: Handle request-level logprobs override

Usage:
  response = client.agents.messages.create(
      agent_id=agent_id,
      messages=[...],
      return_logprobs=True,
      top_logprobs=5,
  )
  print(response.logprobs)  # Per-token log probabilities

4c753f3f3c fix: handle non-JSON responses from LLM provider endpoints (#9362)
When an OpenAI/Anthropic-compatible endpoint returns a non-JSON response
(e.g. HTML error page), the SDK's paginated response parser falls back
to returning a raw string. The post-parser then calls
_set_private_attributes() on that string, causing an AttributeError.

Add explicit AttributeError handling around SDK models.list() calls in
provider check_api_key/list_llm_models_async methods, and add type
guards in convert_response_to_chat_completion to reject raw strings
before Pydantic model construction.

* fix: use LLMBadRequestError instead of ValueError for Anthropic streaming constraint

ValueError maps to HTTP 400 which incorrectly implies a bad client request.
LLMBadRequestError maps to HTTP 502 (Bad Gateway) which correctly signals
that the downstream provider (Anthropic) rejected the proxied request due
to its own constraints.

f20fdc73d1 fix(core): preserve Gemini thought_signature on function calls in non-streaming path (#9351)
* fix(core): preserve Gemini thought_signature on function calls in non-streaming path

The Google Gemini API requires thought_signature to be echoed back on
function call parts in multi-turn conversations. In the non-streaming
request path, the signature was only captured for subsequent function
calls (else branch) but dropped for the first/only function call (if
branch) in convert_response_to_chat_completion. This caused 400
INVALID_ARGUMENT errors on the next turn.

Additionally, when no ReasoningContent existed to carry the signature
(e.g. Gemini 2.5 Flash with include_thoughts=False), the signature was
lost in the adapter layer. Now it falls through to TextContent.

d48932bdb6 fix(core): sanitize Unicode surrogates in all LLM client requests (#9323)
Multiple OpenAI-compatible LLM clients (Azure, Deepseek, Groq, Together, XAI, ZAI)
and Anthropic-compatible clients (Anthropic, MiniMax, Google Vertex) were overriding
request_async/stream_async without calling sanitize_unicode_surrogates, causing
UnicodeEncodeError when message content contained lone UTF-16 surrogates.

Root cause: Child classes override parent methods but omit the sanitization step that
the base OpenAIClient includes. This allows corrupted Unicode (unpaired surrogates
from malformed emoji) to reach the httpx layer, which rejects it during UTF-8 encoding.

Fix: Import and call sanitize_unicode_surrogates in all overridden request methods.
Also removed duplicate sanitize_unicode_surrogates definition from openai_client.py
that shadowed the canonical implementation in letta.helpers.json_helpers.

Return error as failed result instead of re-raising to avoid Datadog alerts for expected user-facing errors like missing tool arguments.

* fix: strip whitespace from API keys before passing to httpx client

Fixes httpx.LocalProtocolError by stripping leading/trailing whitespace
from API keys before passing them to OpenAI/AsyncOpenAI clients. The
OpenAI client library constructs Authorization headers internally, and
invalid header values (like keys with leading spaces) cause protocol
errors.

203b6ead7c fix: remove duplicate provider trace logging and dead code (#9278)
Provider traces were being created twice per step:

2. Make raw trace writes truly fire-and-forget - use asyncio.create_task()
   instead of awaiting, so JSON serialization doesn't block request path

3. Add bounded queue (maxsize=10000) - prevents unbounded memory growth
   under load. Drops traces with warning if queue is full.

4. Fix deprecated asyncio usage - get_running_loop() instead of get_event_loop()

630c147b13 fix: truncate oversized text in embedding requests (#9196)
fix: handle oversized text in embedding requests with recursive chunking

When message text exceeds the embedding model's context length, recursively
split it until all chunks can be embedded successfully.

Changes:
- `tpuf_client.py`: Add `_split_text_in_half()` helper for recursive splitting
- `tpuf_client.py`: Add `_generate_embeddings_with_chunking()` that retries
  with splits on context length errors
- `tpuf_client.py`: Store `message_id` and `chunk_index` columns in Turbopuffer
- `tpuf_client.py`: Deduplicate query results by `message_id`
- `tpuf_client.py`: Use `LettaInvalidArgumentError` instead of `ValueError`
- `tpuf_client.py`: Move LLMClient import to top of file
- `openai_client.py`: Remove fixed truncation (chunking handles this now)
- Add tests for `_split_text_in_half` and chunked query deduplication

* feat: add MiniMax provider support

Add MiniMax as a new LLM provider using their Anthropic-compatible API.

Key implementation details:
- Uses standard messages API (not beta) - MiniMax supports thinking blocks natively
- Base URL: https://api.minimax.io/anthropic
- Models: MiniMax-M2.1, MiniMax-M2.1-lightning, MiniMax-M2 (all 200K context, 128K output)
- Temperature clamped to valid range (0.0, 1.0]
- All M2.x models treated as reasoning models (support interleaved thinking)

Files added:
- letta/schemas/providers/minimax.py - MiniMax provider schema
- letta/llm_api/minimax_client.py - Client extending AnthropicClient
- tests/test_minimax_client.py - Unit tests (13 tests)

- Add request_async_with_telemetry() for non-streaming requests
- Add stream_async_with_telemetry() for streaming requests
- Add set_telemetry_context() to configure agent_id, run_id, step_id

Updates adapters and agents to use new pattern:
- LettaLLMAdapter now accepts agent_id/run_id in constructor
- Adapters call set_telemetry_context() before LLM requests

Introduces a pluggable backend system for provider traces:

- PostgreSQL backend (existing behavior)
- ClickHouse backend (via OTEL instrumentation)

- Multi-backend writes (concurrent via asyncio.gather)
- Primary backend for reads (first in config list)
- Graceful error handling per backend
