In their own words
Future AGI AI Evaluation SDK
Future AGI AI Evaluation SDK is an open-source platform for evaluating, simulating, optimizing, monitoring, and protecting AI agents. Its evaluation options include heuristic, code, LLM-as-judge, and agentic methods, with templates and CI/CD support. traceAI instrumentation converts LLM calls, tool use, retrieval, and chain steps into OpenTelemetry spans. Simulation supports text and voice tests using personas and scenarios; the Free plan includes 1M text simulation tokens and 60 voice minutes per month. The integrations page lists 79 integrations and SDK packages for Python, TypeScript, and Java, including OpenAI, Anthropic, Google GenAI, Vertex AI, AWS Bedrock, and Azure OpenAI. The Apache 2.0 platform offers Docker and SDK self-hosting options. Future AGI says Docker Compose self-hosting keeps traces, datasets, evaluations, and model calls within the customer's network. The platform is presented for startups and enterprise teams building and operating AI agents, with API, web, self-hosted, Linux, macOS, and Windows options. Free usage pauses at its cap; pay-as-you-go usage continues and may incur overage charges.
W&B Weave
W&B Weave provides observability and continuous-improvement tools for production AI agents. It structures traces as sessions and turns, with steps, tools, and sub-agents represented individually. Built-in and custom signals classify interactions, and alerts can be sent through Slack notifications or webhook automations. Its evaluation tools compare results and visualize regressions before deployment; the Playground lets teams compare models and prompting methods against production traces. Safety scorers cover toxicity, bias, personal information, and hallucinations, while quality scorers assess coherence, fluency, and context relevance. Weave works with LangChain and LlamaIndex and supports models from OpenAI, Meta, Amazon Bedrock, and Anthropic. Python and TypeScript libraries are available, as is OpenTelemetry trace submission through an OTLP endpoint. Weave runs on API, Linux, macOS, self-hosted, web, and Windows platforms. The Free plan costs nothing and includes 1 GB of monthly ingestion and 5 GB of storage. Pro costs $60 a month, with 1.5 GB of monthly ingestion; extra ingestion costs $0.10 per MB. A 30-day trial is listed.
