Pydantic Deep Agents is a self-hosted terminal AI assistant and Python framework for building coding, research, and other AI agents. It gives agents tools such as file access, shell commands, planning, memory, sub-agents, sandboxed execution, and MCP connections, and supports different models.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.04506 | $0.04506 |
| Opus 5.5 | $0.01802 | $0.01802 |
| Sonnet 5.5 | $0.00901 | $0.00901 |
| Haiku 4.5 | $0.00451 | $0.00451 |
Grade A, and why
pydantic-deepagents CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Core Components
Agent Factory (pydantic_deep/agent.py)
create_deep_agent(): Main factory function for creating configured agentscreate_default_deps(): Helper for creating DeepAgentDeps with sensible defaults- Built on top of pydantic-ai's Agent class
- Requires pydantic-ai>=2.52.0 (workspaces)
workspace=: the capability that supplies each run's workspace; defaultStateWorkspace()(in-memory, no commands),Falseleaves it toagent.run(workspace=...)
Dependencies (pydantic_deep/deps.py)
DeepAgentDeps: Dataclass holding agent dependencies (todos, subagents, uploads, checkpoint store, message queue)- Passed to agent.run() for runtime configuration
- Holds no files: those live in the run's workspace,
ctx.workspace.upload_file()queues bytes thatwrite_pending_uploads()writes when the run starts
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pydantic-deepagents CLAUDE.md is an instructions file published in the GitHub repository vstorm-co/pydantic-deepagents (1,115 stars, last pushed 7d ago), licensed MIT. It adds 4,506 tokens to every session, about $0.0180 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
