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 | $0.00000 | $0.00507 |
| Opus 5 | $0.00000 | $0.00253 |
| Sonnet 5 | $0.00000 | $0.00101 |
| Haiku 4.5 | $0.00000 | $0.00051 |
Grade A, and why
flash scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Flash firmware to the connected ESP32-S3-CAM board
Usage: /flash <project_path> (same path used with /build)
Steps
-
Activate IDF:
. ~/esp/esp-idf/export.sh 2>/dev/null -
Detect port. ESP32-S3 exposes native USB-Serial/JTAG — no CP2102, just
usbmodem*:PORT=$(ls /dev/cu.usbmodem* 2>/dev/null | head -1) # Expect /dev/cu.usbmodem3101 on this host. -
Flash (no separate bootloader button needed — DTR/RTS auto-enter download mode):
idf.py -C <project_path> -B /tmp/ws-esp32s3-build/$(basename <project_path>) \ -p "$PORT" flash 2>&1 | tail -12 -
A ~5 MB vendor example flashes in ~10 s. Expect final lines:
Hash of data verified. Leaving... Hard resetting via RTS pin... Done
Warnings
- Do NOT run
idf.py flash monitorcombined in a non-TTY shell (piped, subshell, Claude Code agent). Monitor exits immediately → flash aborts mid-write → "No bootable app" panic. Always flash first, then monitor separately — see/monitor. - If the port is busy,
esptoolfails with "Could not open serial port". A previous serial reader is still attached — kill it. - If the chip is in a bad state and auto-download fails, force bootloader mode: unplug USB → hold BOOT → plug USB → release BOOT. Then retry flash.
Board Is Currently Running Factory Firmware?
Flashing overwrites Waveshare's factory image (multi-app launcher with Settings/Camera/Music/XiaoZhi AI).
The factory .bin lives at ref/demo/ESP32-S3-CAM-OVxxxx/Firmware/ESP32-S3-CAM-XXXX-Factory.bin (plus per-LCD-size variants).
To restore it, use /restore-factory.
Report
- Success: port used, bytes written, final "Hard resetting" line.
- Failure: the esptool error line, with a suggested next action.
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.

flash is a command published in the GitHub repository chayuto/ws-ESP32-S3-CAM (5 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 507 tokens. 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 2026-08-31.
