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 | $0.00107 | $0.01643 |
| Opus 5 | $0.00053 | $0.00822 |
| Sonnet 5 | $0.00021 | $0.00329 |
| Haiku 4.5 | $0.00011 | $0.00164 |
Grade A, and why
codex-history-ingest 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 9d 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.
This is a copy
81% identical to codex-history-ingest — 135 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

The opening of the file, as written. The whole thing — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex History Ingest — Conversation Mining for Logseq
REQUIRED: Invoke llm-wiki skill first for Logseq syntax and file format rules.
You are extracting knowledge from the user's past Codex sessions and distilling it into the Logseq wiki. Session logs are rich but noisy: focus on durable knowledge, not operational telemetry.
This skill can be invoked directly or via the wiki-history-ingest router (/wiki-history-ingest codex).
Before You Start
- Read
~/.logseq-wiki/configto getLOGSEQ_VAULT_PATHandCODEX_HISTORY_PATH(default to~/.codexif unset) - Read
wiki/_manifest.jsonat the vault root to check what has already been ingested - Read
wiki/_master-index.mdat the vault root to understand what the wiki already contains
Ingest Modes
Append Mode (default)
Check wiki/_manifest.json for each source file. Only process:
- Files not in the manifest (new session rollouts, new index files)
- Files whose modification time is newer than
ingested_atin the manifest
Use this mode for regular syncs.
Full Mode
Process everything regardless of manifest. Use after wiki-rebuild or if the user explicitly asks for a full re-ingest.
Codex Data Layout
Codex stores local artifacts under ~/.codex/.
~/.codex/
├── sessions/ # Session rollout logs by date
│ └── YYYY/MM/DD/
│ └── rollout-<timestamp>-<id>.jsonl
├── archived_sessions/ # Archived rollout logs
├── session_index.jsonl # Lightweight index of thread id/name/updated_at
├── history.jsonl # Local transcript history (if persistence enabled)
├── config.toml # User config (contains history settings)
└── state_*.sqlite / logs_*.sqlite # Runtime DBs (usually skip)
Key data sources ranked by value
session_index.jsonl— best inventory source for IDs, titles, and freshnesssessions/**/rollout-*.jsonl— rich structured transcript eventshistory.jsonl— useful fallback/timeline aid if enabled
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

Plan and then execute a migration of a project from the mem0 open-source / self-hosted SDK (the local Memory class) to the mem0 Platform / hosted / managed SDK (the MemoryClient class). Use this whenever a developer wants to move, switch, or migrate their mem0 usage off OSS/self-hosted to the hosted API — e.g.…
