feat(langchain): support SystemMessage in create_agent's system_prompt ( #34055 )
...
* `create_agent`'s `system_prompt` allows `str | SystemMessage`
* added `system_message: SystemMessage` on `ModelRequest`
* `ModelRequest.system_prompt` is a function of `system_message.text`,
now deprecated
* disallow setting `system_prompt` and `system_message`
* `ModelRequest.system_prompt` can still be set (w/ custom setattr) for
custom backwards compat, but the updates just get propogated to the
`ModelRequest.system_message`

fix(openai): make GPT-5 temperature validation case-insensitive ( #34012 )
...
Fixed a bug where GPT-5 temperature validation was case-sensitive,
causing issues when users
specified Azure deployment names or model names in uppercase (e.g.,
`"GPT-5-2025-01-01"`, `"GPT-5-NANO"`). The validation now correctly
handles model names regardless of case.
Changes made:
- Updated `validate_temperature()` method in `BaseChatOpenAI` to perform
case-insensitive
model name comparisons
- Updated `_get_encoding_model()` method to use case-insensitive checks
for tiktoken encoder
selection
- Added comprehensive unit tests to verify case-insensitive behavior
with various case
combinations
**Issue:** Fixes #34003
**Dependencies:** None
**Test Coverage:**
- All existing tests pass
- New test `test_gpt_5_temperature_case_insensitive` covers uppercase,
lowercase, and
mixed-case model names
- Tests verify both non-chat GPT-5 models (temperature removed) and chat
models (temperature
preserved)
- Lint and format checks pass (`make lint`, `make format`)

fix(core): Decouple provider prefix from model name in init_chat_mode… ( #34046 )
...
:…l logic
Addresses Issue #34007 .
Fixes a bug where aliases like 'mistral:' were inferred correctly as a
provider but the prefix was not stripped from the model name, causing
API 400 errors. Added logic to strip prefix when inference succeeds.
**Description**
This PR resolves a logic error in `init_chat_model` where inferred
provider aliases (specifically `mistral:`) were correctly identified but
not stripped from the model string.
**The Problem**
When passing a string like `mistral:ministral-8b-latest`, the factory
logic correctly inferred the provider as `mistralai` but failed to enter
the string-splitting block because the alias `mistral` was not in the
hardcoded `_SUPPORTED_PROVIDERS` list. This caused the raw string
`mistral:ministral-8b-latest` to be passed to the `ChatMistralAI`
constructor, resulting in a 400 API error.
**The Fix**
I updated `_parse_model` in
`libs/langchain/langchain/chat_models/base.py`. The logic now attempts
to infer the provider from the prefix *before* determining whether to
split the string. This ensures that valid aliases trigger the stripping
logic, passing only the clean `model_name` to the integration class.
**Issue**
Fixes #34007
**Dependencies**
None.
**Verification**
Validated locally with a reproduction script:
- Input: `mistral:ministral-8b-latest`
- Result: Successfully instantiates `ChatMistralAI` with
`model="ministral-8b-latest"`.
- Validated that standard inputs (e.g., `gpt-4o`) remain unaffected.

Support injection of injected args (like `InjectedToolCallId`,
`ToolRuntime`) when an `args_schema` is specified that doesn't contain
said args.
This allows for pydantic validation of other args while retaining the
ability to inject langchain specific arguments.

fixes https://github.com/langchain-ai/langchain/issues/31688
Taking a deep dive here reminded me that we definitely need to revisit
our internal tooling logic, but I don't think we should do that in this
PR.

feat(core): add proxy support for mermaid png rendering ( #32400 )
...
### Description
This PR adds support for configuring HTTP/HTTPS proxies when rendering
Mermaid diagrams as PNG images using the remote Mermaid.INK API. This
enhancement allows users in restricted network environments to access
the API via a proxy, making the remote rendering feature more robust and
accessible.
The changes include:
- Added optional `proxies` parameter to `draw_mermaid_png` and
`_render_mermaid_using_api` functions
- Updated `Graph.draw_mermaid_png` method to support and pass through
proxy configuration
- Enhanced docstrings with usage examples for the new parameter
- Maintained full backward compatibility with existing code
### Usage Example
```python
proxies = {
"http": "http://127.0.0.1:7890 ",
"https": "http://127.0.0.1:7890 "
}
display(Image(chain.get_graph().draw_mermaid_png(proxies=proxies)))
```
### Dependencies
No new dependencies required. Uses existing `requests` library for HTTP
requests.

fix(openai): Respect 300k token limit for embeddings API requests ( #33668 )
...
## Description
Fixes #31227 - Resolves the issue where `OpenAIEmbeddings` exceeds
OpenAI's 300,000 token per request limit, causing 400 BadRequest errors.
## Problem
When embedding large document sets, LangChain would send batches
containing more than 300,000 tokens in a single API request, causing
this error:
```
openai.BadRequestError: Error code: 400 - {'error': {'message': 'Requested 673477 tokens, max 300000 tokens per request'}}
```
The issue occurred because:
- The code chunks texts by `embedding_ctx_length` (8191 tokens per
chunk)
- Then batches chunks by `chunk_size` (default 1000 chunks per request)
- **But didn't check**: Total tokens per batch against OpenAI's 300k
limit
- Result: `1000 chunks × 8191 tokens = 8,191,000 tokens` → Exceeds
limit!
## Solution
This PR implements dynamic batching that respects the 300k token limit:
1. **Added constant**: `MAX_TOKENS_PER_REQUEST = 300000`
2. **Track token counts**: Calculate actual tokens for each chunk
3. **Dynamic batching**: Instead of fixed `chunk_size` batches,
accumulate chunks until approaching the 300k limit
4. **Applied to both sync and async**: Fixed both
`_get_len_safe_embeddings` and `_aget_len_safe_embeddings`
## Changes
- Modified `langchain_openai/embeddings/base.py`:
- Added `MAX_TOKENS_PER_REQUEST` constant
- Replaced fixed-size batching with token-aware dynamic batching
- Applied to both sync (line ~478) and async (line ~527) methods
- Added test in `tests/unit_tests/embeddings/test_base.py`:
- `test_embeddings_respects_token_limit()` - Verifies large document
sets are properly batched
## Testing
All existing tests pass (280 passed, 4 xfailed, 1 xpassed).
New test verifies:
- Large document sets (500 texts × 1000 tokens = 500k tokens) are split
into multiple API calls
- Each API call respects the 300k token limit
## Usage
After this fix, users can embed large document sets without errors:
```python
from langchain_openai import OpenAIEmbeddings
from langchain_chroma import Chroma
from langchain_text_splitters import CharacterTextSplitter
# This will now work without exceeding token limits
embeddings = OpenAIEmbeddings()
documents = CharacterTextSplitter().split_documents(large_documents)
Chroma.from_documents(documents, embeddings)
```
Resolves #31227

fix(anthropic): execute bash + file tools via tool node ( #33960 )
...
* use `override` instead of directly patching things on `ModelRequest`
* rely on `ToolNode` for execution of tools related to said middleware,
using `wrap_model_call` to inject the relevant claude tool specs +
allowing tool node to forward them along to corresponding langchain tool
implementations
* making the same change for the native shell tool middleware
* allowing shell tool middleware to specify a name for the shell tool
(negative diff then for claude bash middleware)
long term I think the solution might be to attach metadata to a tool to
map the provider spec to a langchain implementation, which we could also
take some lessons from on the MCP front.
