Eugene Yurtsev	99adcdb1c9	Add dedicated `type` attribute to be used solely for serialization purposes (#11585 ) Adds standard `type` field for all messages that will be serialized/validated by pydantic. * The presence of `type` makes it easier for developers consuming schemas to write client code to serialize/deserialize. * In LangServe `type` will be used for both validation and will appear in the generated openapi specs	11 months ago

Todd Kerpelman	0bff399af1	Make metadata from the url_selenium loader match that of the web_base loader (#11617 ) Description: I noticed the metadata returned by the url_selenium loader was missing several values included by the web_base loader. (The former returned `{source: ...}`, the latter returned `{source: ..., title: ..., description: ..., language: ...}`.) This change fixes it so both loaders return all 4 key value pairs. Files have been properly formatted and all tests are passing. Note, however, that I am not much of a python expert, so that whole "Adding the imports inside the code so that tests pass" thing seems weird to me. Please LMK if I did anything wrong.	11 months ago

Ash Vardanian	1acfe86353	Accelerating Math Utils with SimSIMD (#11566 ) LangChain relies on NumPy to compute cosine distances, which becomes a bottleneck with the growing dimensionality and number of embeddings. To avoid this bottleneck, in our libraries at [Unum](https://github.com/unum-cloud), we have created a specialized package - [SimSIMD](https://github.com/ashvardanian/simsimd), that knows how to use newer hardware capabilities. Compared to SciPy and NumPy, it reaches 3x-200x performance for various data types. Since publication, several LangChain users have asked me if I can integrate it into LangChain to accelerate their workflows, so here I am 🤗 ## Benchmarking To conduct benchmarks locally, run this in your Jupyter: ```py import numpy as np import scipy as sp import simsimd as simd import timeit as tt def cosine_similarity_np(X: np.ndarray, Y: np.ndarray) -> np.ndarray: X_norm = np.linalg.norm(X, axis=1) Y_norm = np.linalg.norm(Y, axis=1) with np.errstate(divide="ignore", invalid="ignore"): similarity = np.dot(X, Y.T) / np.outer(X_norm, Y_norm) similarity[np.isnan(similarity) \| np.isinf(similarity)] = 0.0 return similarity def cosine_similarity_sp(X: np.ndarray, Y: np.ndarray) -> np.ndarray: return 1 - sp.spatial.distance.cdist(X, Y, metric='cosine') def cosine_similarity_simd(X: np.ndarray, Y: np.ndarray) -> np.ndarray: return 1 - simd.cdist(X, Y, metric='cosine') X = np.random.randn(1, 1536).astype(np.float32) Y = np.random.randn(1, 1536).astype(np.float32) repeat = 1000 print("NumPy: {:,.0f} ops/s, SciPy: {:,.0f} ops/s, SimSIMD: {:,.0f} ops/s".format( repeat / tt.timeit(lambda: cosine_similarity_np(X, Y), number=repeat), repeat / tt.timeit(lambda: cosine_similarity_sp(X, Y), number=repeat), repeat / tt.timeit(lambda: cosine_similarity_simd(X, Y), number=repeat), )) ``` ## Results I ran this on an M2 Pro Macbook for various data types and different number of rows in `X` and reformatted the results as a table for readability: \| Data Type \| NumPy \| SciPy \| SimSIMD \| \| :--- \| ---: \| ---: \| ---: \| \| `f32, 1` \| 59,114 ops/s \| 80,330 ops/s \| 475,351 ops/s \| \| `f16, 1` \| 32,880 ops/s \| 82,420 ops/s \| 650,177 ops/s \| \| `i8, 1` \| 47,916 ops/s \| 115,084 ops/s \| 866,958 ops/s \| \| `f32, 10` \| 40,135 ops/s \| 24,305 ops/s \| 185,373 ops/s \| \| `f16, 10` \| 7,041 ops/s \| 17,596 ops/s \| 192,058 ops/s \| \| `f16, 10` \| 21,989 ops/s \| 25,064 ops/s \| 619,131 ops/s \| \| `f32, 100` \| 3,536 ops/s \| 3,094 ops/s \| 24,206 ops/s \| \| `f16, 100` \| 900 ops/s \| 2,014 ops/s \| 23,364 ops/s \| \| `i8, 100` \| 5,510 ops/s \| 3,214 ops/s \| 143,922 ops/s \| It's important to note that SimSIMD will underperform if both matrices are huge. That, however, seems to be an uncommon usage pattern for LangChain users. You can find a much more detailed performance report for different hardware models here: - [Apple M2 Pro](https://ashvardanian.com/posts/simsimd-faster-scipy/#appendix-1-performance-on-apple-m2-pro). - [4th Gen Intel Xeon Platinum](https://ashvardanian.com/posts/simsimd-faster-scipy/#appendix-2-performance-on-4th-gen-intel-xeon-platinum-8480). - [AWS Graviton 3](https://ashvardanian.com/posts/simsimd-faster-scipy/#appendix-3-performance-on-aws-graviton-3). ## Additional Notes 1. Previous version used `X = np.array(X)`, to repackage lists of lists. It's an anti-pattern, as it will use double-precision floating-point numbers, which are slow on both CPUs and GPUs. I have replaced it with `X = np.array(X, dtype=np.float32)`, but a more selective approach should be discussed. 2. In numerical computations, it's recommended to explicitly define tolerance levels, which were previously avoided in `np.allclose(expected, actual)` calls. For now, I've set absolute tolerance to distance computation errors as 0.01: `np.allclose(expected, actual, atol=1e-2)`. --- - Dependencies: adds `simsimd` dependency - Tag maintainer: @hwchase17 - Twitter handle: @ashvardanian --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	11 months ago

This includes an implementation with docstrings, integration tests, a notebook, and documentation on the docs pages. - Updated the Momento dependency in pyproject.toml and the lock file to enable access to MVI. - Refactored the Momento cache and chat history session store to prefer using "MOMENTO_API_KEY" over "MOMENTO_AUTH_TOKEN" for consistency with MVI. This change is backwards compatible with the previous "auth_token" variable usage. Updated the code and tests accordingly. Dependencies: - Updated Momento dependency in pyproject.toml. Testing: - Run the integration tests with a Momento API key. Get one at the [Momento Console](https://console.gomomento.com) for free. MVI is available in AWS us-west-2 with a superuser key. - `MOMENTO_API_KEY=<your key> poetry run pytest tests/integration_tests/vectorstores/test_momento_vector_index.py` Tag maintainer: @eyurtsev Twitter handle: Please mention @momentohq for this addition to langchain.
