It offers Semantic Search, Question-Answer Extraction, Classification, Customizable Models (PyTorch/TensorFlow/Keras), etc. Built from scratch in Go, Weaviate stores both objects and vectors, allowing for combining vector search with structured filtering and the fault tolerance of a cloud-native database.

APIs act as the "front door" for applications to access data, business logic, or functionality from your backend services. Using API Gateway, you can create RESTful APIs and WebSocket APIs that enable real-time two-way communication applications. API Gateway supports containerized and serverless workloads, as well as web applications.API Gateway handles all the tasks involved in accepting and processing up to hundreds of thousands of concurrent API calls, including traffic management, CORS support, authorization and access control, throttling, monitoring, and API version management. API Gateway has no minimum fees or startup costs. You pay for the API calls you receive and the amount of data transferred out and, with the API Gateway tiered pricing model, you can reduce your cost as your API usage scales.LLMâ€‹See a usage example.from langchain.llms import AmazonAPIGatewayapi_url = "https://<api_gateway_id>.execute-api.<region>.amazonaws.com/LATEST/HF"llm = AmazonAPIGateway(api_url=api_url)# These are sample parameters for Falcon 40B Instruct Deployed from Amazon SageMaker JumpStartparameters = {    "max_new_tokens": 100,    "num_return_sequences": 1,    "top_k": 50,

As you iterate new versions of your LLM application, you can compare their performance across all of the different quality metrics you've set up. You'll also be able to view evaluations at a record level, and explore the chain metadata for each record.tru.run_dashboard() # open a Streamlit app to exploreFor more information on TruLens, visit trulens.orgPreviousTrelloNextTwitterWhat is TruLens?Quick startCommunityDiscordTwitterGitHubPythonJS/TSMoreHomepageBlogCopyright Â© 2023 LangChain, Inc.

It is broken into two parts: installation and setup, and then references to specific Redis wrappers.Installation and Setupâ€‹Install the Redis Python SDK with pip install redisWrappersâ€‹All wrappers needing a redis url connection string to connect to the database support either a stand alone Redis server
or a High-Availability setup with Replication and Redis Sentinels.Redis Standalone connection urlâ€‹For standalone Redis server the official redis connection url formats can be used as describe in the python redis modules
"from_url()" method Redis.from_urlExample: redis_url = "redis://:secret-pass@localhost:6379/0"Redis Sentinel connection urlâ€‹For Redis sentinel setups the connection scheme is "redis+sentinel".
This is an un-offical extensions to the official IANA registered protocol schemes as long as there is no connection url
for Sentinels available.Example: redis_url = "redis+sentinel://:secret-pass@sentinel-host:26379/mymaster/0"The format is  redis+sentinel://[[username]:[password]]@[host-or-ip]:[port]/[service-name]/[db-number]
with the default values of "service-name = mymaster" and "db-number = 0" if not set explicit.
The service-name is the redis server monitoring group name as configured within the Sentinel. The current url format limits the connection string to one sentinel host only (no list can be given) and
booth Redis server and sentinel must have the same password set (if used).Redis Cluster connection urlâ€‹Redis cluster is not supported right now for all methods requiring a "redis_url" parameter.
The only way to use a Redis Cluster is with LangChain classes accepting a preconfigured Redis client like RedisCache


(example below).Cacheâ€‹The Cache wrapper allows for Redis to be used as a remote, low-latency, in-memory cache for LLM prompts and responses.Standard Cacheâ€‹The standard cache is the Redis bread & butter of use case in production for both open source and enterprise users globally.To import this cache:from langchain.cache import RedisCacheTo use this cache with your LLMs:import langchainimport redisredis_client = redis.Redis.from_url(...)langchain.llm_cache = RedisCache(redis_client)Semantic Cacheâ€‹Semantic caching allows users to retrieve cached prompts based on semantic similarity between the user input and previously cached results.

With Portkey, you can  view detailed metrics & logs for all requests,  enable semantic cache to reduce latency & costs,  implement automatic retries & fallbacks for failed requests,  add custom tags to requests for better tracking and analysis and more.Using Portkey with Langchainâ€‹Using Portkey is as simple as just choosing which Portkey features you want, enabling them via headers=Portkey.Config and passing it in your LLM calls.To start, get your Portkey API key by signing up here. (Click the profile icon on the top left, then click on "Copy API Key")For OpenAI, a simple integration with logging feature would look like this:from langchain.llms import OpenAIfrom langchain.utilities import Portkey# Add the Portkey API Key from your accountheaders = Portkey.Config(    api_key = "<PORTKEY_API_KEY>")llm = OpenAI(temperature=0.9, headers=headers)llm.predict("What would be a good company name for a company that makes colorful socks?")Your logs will be captured on your Portkey dashboard.A common Portkey X Langchain use case is to trace a chain or an agent and view all the LLM calls originating from that request. Tracing Chains & Agentsâ€‹from langchain.agents import AgentType,


request. Tracing Chains & Agentsâ€‹from langchain.agents import AgentType, initialize_agent, load_tools  from langchain.llms import OpenAIfrom langchain.utilities import Portkey# Add the Portkey API Key from your accountheaders = Portkey.Config(    api_key = "<PORTKEY_API_KEY>",    trace_id = "fef659")llm = OpenAI(temperature=0, headers=headers)  tools = load_tools(["serpapi", "llm-math"], llm=llm)  agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True)    # Let's test it out!  agent.run("What was the high temperature in SF yesterday in Fahrenheit? What is that number raised to the .023 power?")You can see the requests' logs along with the trace id on Portkey dashboard:Advanced Featuresâ€‹Logging: Log all your LLM requests automatically by sending them through Portkey. Each request log contains timestamp, model name, total cost, request time, request json, response json, and additional Portkey features.Tracing: Trace id can be passed along with each request and is visibe on the logs on Portkey dashboard. You can also set a distinct trace id for each request. You can append user feedback to a trace id as well.Caching: Respond to previously served customers queries from cache instead of sending them again to OpenAI. Match exact strings OR semantically similar strings. Cache can save costs and reduce latencies by 20x.Retries: Automatically reprocess any unsuccessful API requests upto 5 times. Uses an exponential backoff strategy, which spaces out retry attempts to prevent network overload.Tagging: Track and audit each user interaction in high detail with predefined tags.FeatureConfig KeyValue (Type)Required/OptionalAPI Keyapi_keyAPI Key (string)âœ…
