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 | $0.00082 | $0.06295 |
| Opus 5.5 | $0.00033 | $0.02518 |
| Sonnet 5.5 | $0.00016 | $0.01259 |
| Haiku 4.5 | $0.00008 | $0.00630 |
Grade A, and why
openproxy-combos scanned grade A with 1 finding 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 29d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

openproxy-combos — build and operate fallback chains
A combo is a named, ordered list of <provider>/<model> entries that
OpenProxy dispatches as a single model. It is the router's failover unit: a
client sends one model name, the combo walks the list, and the first member
that answers wins.
Combos are one of two core data types (alongside providers). They are stored
in the data dir, edited from /dashboard/combos, and are first-class entries
in GET /v1/models.
Everything below was verified against the source in this repo. Where OpenProxy
deliberately diverges from the 9router reference, the divergence is called
out and docs/parity-9router.md is cited.
0 · Decide CLI or REST first
This is the one decision that trips people up, so settle it before writing anything.
openproxy combo … is a local-only command. src/cli/mod.rs handles
Command::Combo by calling Db::load() and handing the DB straight to
combo::run — it never consults --url / --api-key. Two consequences,
both confirmed by running the binary:
openproxy combo create --url http://127.0.0.1:4623 --api-key $KEYwrites to the local data dir, not to the server. The server's/api/combosstays empty.--urlis silently ignored.- A combo created with the CLI while a server is running is invisible to
that server — absent from
/api/combosand fromGET /v1/models— until the server is restarted and reloads the data dir.
| Situation | Use |
|---|---|
| No server running, or you are about to restart one | openproxy combo … CLI |
| A server is already running | REST API (/api/combos) — the only path that goes through the live process |
| Declarating many combos at once | openproxy combo apply --from-file against a stopped server, or the REST API via curl |
If you have already used the CLI against a live server, restart it:
openproxy server stop && openproxy server start --detach --no-open

The stored record (Combo in src/types/mod.rs) is camelCase on the wire,
with the extras flattened into the top level:
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.

openproxy-combos is a skill published in the GitHub repository quangdang46/openproxy (29 stars, last pushed 5d ago), licensed MIT. It adds 82 tokens to every session and 6,295 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-29.
