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 | $0.00580 | $0.00580 |
| Opus 5.5 | $0.00232 | $0.00232 |
| Sonnet 5.5 | $0.00116 | $0.00116 |
| Haiku 4.5 | $0.00058 | $0.00058 |
Grade A, and why
Synaptic-Tuner 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.
How it starts
The opening of the file, as written. The whole thing — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Synaptic Tuner
Synthetic dataset generation and LLM fine-tuning engine. Teacher models generate training data, which is used for SFT/KTO fine-tuning of smaller models. The engine is consumed as a git submodule by host projects; hosts own configuration, credentials, and mutable state.
How to work here
AGENTS.mdcarries the standing engineering discipline (fine-tuning workflow, config-first generation, HF Jobs, Modal). Read it before changing those areas..skills/is the canonical skill source;.agents/skillsand.claude/skillsare generated mirrors. After editing a skill runpython3 .skills/scripts/sync_skill_trees.py, then--check.- Load the relevant skill before starting:
fine-tuningfor training, cloud jobs, evaluation runs, experiments and dataset publishing;synethetic-data-generationfor synthetic data;evaluationfor the eval system;upload-deploymentfor model upload;research-reportingfor research notes. - Prefer existing CLIs, checked-in scripts and skills over ad hoc scripts or manual API probing. If a capability is missing, add it as a checked-in workflow and update the skill rather than leaving a one-off.
- Docs entry points:
docs/common-tasks.md(how to run things),docs/troubleshooting.md(errors and recovery),docs/project-reference.md(scripts, configs, env vars, data formats). - Discover resources with the CLI rather than from memory:
./run.sh status,./run.sh doctor,./run.sh list <resource>(python tuner.pydirectly, or.\run.ps1on Windows).
Rules
- Never write outputs to
/tmp. Generated files stay in the repository (docs/,Datasets/,scratch/); test outputs go underscratch/. - Stop early on errors. Watch output and kill a run as soon as it looks wrong.
- No hardcoding of scenario-specific behavior in SynthChat. Tool-call formats,
workspace structures and label mappings come from config under
SynthChat/config/. The bundleduseToolswrapper is a toy example, not the canonical format. - No backward-compatibility shims. Move code and update imports directly; no re-exports, dual signatures or deprecated wrappers.
- Secrets are referenced by name only and resolved at execution time. Never put credential values in code, configs, logs, argv or commit messages.
- Do not record session state, progress or status in this file. It holds only
durable working rules; everything time-bound belongs in
docs/.
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.

Synaptic-Tuner CLAUDE.md is an instructions file published in the GitHub repository ProfSynapse/Synaptic-Tuner (28 stars, last pushed 3d ago), licensed MIT. It adds 580 tokens to every session, about $0.0023 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.
