Cognee is an AI memory platform that stores information in a self-hosted knowledge graph so agents can retain context across sessions. It ingests data, connects related information, and helps agents retrieve it for reasoning and actions. The catalogue includes skills and instructions that extend agent workflows around Cognee.

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 | $0.00065 | $0.03646 |
| Opus 5.5 | $0.00026 | $0.01458 |
| Sonnet 5.5 | $0.00013 | $0.00729 |
| Haiku 4.5 | $0.00006 | $0.00365 |
Grade A, and why
cognee-improve-sessions 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 241 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Session memory and improve()
cognee has two kinds of memory:
- Session memory: a fast cache of conversation turns, agent traces, and
feedback, keyed by
session_id. Writing is instant, with no LLM extraction. - The permanent graph: what
remember()builds without a session.
improve() connects them. It bridges session content into the graph and
enriches the graph itself. remember() calls it automatically, so most
users never call it directly.
import cognee
# Session write: returns immediately; improve() bridges it in the background
await cognee.remember("User prefers dark mode.", session_id="chat_1")
# Session-aware query: session cache first, then the graph
results = await cognee.recall("What does the user prefer?", session_id="chat_1")
# Bridge sessions into a dataset's graph explicitly
result = await cognee.improve(dataset="main_dataset", session_ids=["chat_1"])
print(result.status, result.stage_summary())
await cognee.wait_for_background_tasks() # before a script exits
Use it
Writing session memory
| What | How |
|---|---|
| A fact or note | remember(text, session_id=...) (stored as a Q&A entry with the text as the answer) |
| A Q&A turn | recall(query, session_id=...) with a completion search type saves the turn itself; or remember(cognee.QAEntry(question=..., answer=...), session_id=...) |
| An agent step | remember(cognee.TraceEntry(origin_function=..., status="success", ...), session_id=...), or the @cognee.agent_memory(save_session_traces=True) decorator |
| Pin a session to a project / node set | node_set=[...] on the first QAEntry/TraceEntry (or as a kwarg on any session remember) pins it; later writes repeat or omit it, a different set raises cognee.SessionNodeSetConflictError (HTTP 409). improve() keeps the set on everything it bridges, so recall(node_name=[...]) scopes to the project |
| Feedback on an answer | remember(cognee.FeedbackEntry(qa_id=..., feedback_score=...), session_id=...) or cognee.session.add_feedback(session_id, qa_id, feedback_text=..., feedback_score=...) |
| Read a session | cognee.session.get_session(session_id, last_n=...) |
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.

cognee-improve-sessions is a skill published in the GitHub repository topoteretes/cognee (33,094 stars, last pushed today), licensed Apache-2.0. It adds 65 tokens to every session and 3,646 once invoked, about $0.0003 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 2026-09-30.
