Pydantic

Open Source

Type-safe Python agent framework from the Pydantic team with model-agnostic providers and durable execution integrations.

Curated by Tiberiu ArvaVerified

MITVersion 2.52.0Released 2026-09-29
DocsRepository

Strengths

  • Typed tools, deps and structured outputs
  • Temporal/DBOS/Prefect durable execution
  • OpenTelemetry tracing via Logfire

Practitioner note

Good fit for Python teams that want typed, testable agent code and to swap model providers by string; pair with Temporal or DBOS for long-running work. v1 still gets security patches (v1.107.7 alongside v2.52.0), so pin a major version deliberately.

Governance posture

Reviewed 2026-09-30
YesData residency

Self-hosted library; operator controls placement and model provider (Logfire cloud is optional and separate).

Source
YesDeployment model

OSS library run in the operator's own process; no hosted control plane required. (self-hosted)

Source
PartialAudit logging

No built-in audit log; OpenTelemetry instrumentation (optionally to Logfire) must be wired up by the operator.

Source
N/ASOC 2

Self-hosted library; SOC 2 applies to the operator's infrastructure, not the package.

N/AISO 27001

Self-hosted library; ISO 27001 applies to the operator's ISMS, not the package.

N/AISO 42001

Self-hosted library; ISO 42001 applies to the deploying organisation.

N/AEU AI Act

Developer component, not an AI system placed on the market; obligations rest with the deployer. (role: not-applicable)

EU AI Act obligations

Risk tier: Not applicable · as of 2026-08-23

Source-backed information mapped from Pydantic AI's tracked risk tier — not legal advice. Obligations depend on how your organisation deploys the system; see the full obligation reference and timeline.

This record's EU AI Act risk tier is marked not applicable, so no tier-specific obligations attach. Deployers embedding it in an AI system in scope of the Act should assess that system's own tier.
