glyphh

Ada for Python: your models in Ada Cloud, https://ada.glyphh.ai, called with an API key. Python 3.9 or later, no dependencies.

pip install glyphh

from glyphh import Ada, LimitError

ada = Ada()                     # GLYPHH_API_KEY from the environment; or Ada(key="glyphh_ak_...")

d = ada.decide("tickets", {"ticket": {"what": {"plan": "pro", "text": "charged twice"}}})
if d.ask:                       # a person should decide: d.outcome is the best guess, for them to see
    send_to_a_person(d)
else:
    act(d.outcome)              # d.probabilities, d.expected_cost, d.receipts: the precedents it stands on

tickets = ada.model("tickets")
tickets.record({"ticket": {...}}, "refund")                     # a confirmed outcome: the next case learns from it

The key is made on the platform's API Keys page (https://platform.glyphh.ai), or by Claude through the Glyphh connector; it acts in your org, with the clearance it was made with. GLYPHH_ADA_URL moves the address (a local server under test); 3.0's GLYPHH_RUNTIME_URL and GLYPHH_RUNTIME_KEY are still read.

From nothing to a decision

tickets = ada.create_model("tickets", spec)                     # the spec as JSON: layers, segments, roles, output
job = tickets.import_file("history.csv", mapping={"Plan": "ticket.what.plan", "Result": "outcome"},
                          on_progress=lambda j: print(j.state, j.percent))
print(job.result["added"], job.result["refused"], job.result["refusals"][:3])

bt = tickets.backtest([{"settings": {"word_evidence": 0}, "name": "no word evidence"}], holdout={"newest": 200})
print(bt.result["active"]["accuracy"], bt.result["candidates"][0]["change"])
tickets.settings({"word_evidence": 0}, note="cost 8% less on the last 200", backtest=bt.id)   # a new version
tickets.activate(1)                                            # and back
tickets.export(to="tickets.zip")                               # everything, as a zip: never locked in

Typed outputs and unions

On ada-1-2-beta, a named output's kind says what its answer is: score, noul, number, many or choice (the default), and when makes an output a branch of a union. Record each in its own terms; read what its kind adds:

tickets = ada.model("tickets")
tickets.record(data, outcomes={"kind": "billing", "refund": 120, "urgent": True, "tags": ["web"]})
d = ada.decide("tickets", data, outputs=["kind", "severity", "refund", "urgent", "tags"])
d.outputs["urgent"].p            # a noul's P(true)
d.outputs["refund"].value        # a number's expected value
d.outputs["severity"].applies    # False: a bug's severity does not arise for a billing case
d.outputs["tags"].outcome        # a many output's list

Ada versions

Every model version runs one Ada version, named ada-<major>-<minor> (-beta for a beta): ada-1-0 is the latest stable today, ada-1-1-beta a beta. A model's answers are always computed by its own Ada version; moving to another is your choice, made with a backtest in front of you.

for v in ada.ada.versions():                                   # newest first: name, status, dates, notes, your models on it
    print(v.name, v.status, v.ends, v.changes_answers, v.models)

tickets = ada.create_model("tickets", spec)                     # the latest stable; ada="ada-1-1-beta" to opt in to a beta
info = tickets.info()
print(info.ada, info.ada_status, info.ada_notice)              # ada-1-0 stable None; each of versions() has .ada too

bt = tickets.backtest(ada="ada-1-1-beta")                       # the active spec, learned and scored on that Ada
print(bt.result["active"]["cost"], "->", bt.result["candidates"][0]["cost"])
before = info.version
moved = tickets.upgrade("ada-1-1-beta", note="2 fewer wrong on the last 200", backtest=bt.id)   # a re-encode, waited for
tickets.activate(before)                                       # and back, on the Ada it ran before

upgrade() with no ada moves to the latest stable; an older version is a downgrade, allowed while it is kept. A beta is never the default. A deprecated version still answers until its end date, then the model is moved to the latest stable for you (never left unable to answer); while it runs one, or just after it was moved, the client warns AdaDeprecationWarning (once per client). A name refused is never substituted: AdaVersionUnknownError, AdaVersionRetiredError, AdaVersionDeprecatedError (for a new model or as an upgrade's target), AdaBetaClosedError, AdaVersionUnavailableError, each with ada and latest (the latest stable, the fix).

The SDK speaks contract SUPPORTED_CONTRACT (5) and was made against SUPPORTED_ADA (ada-1-0, ada-1-1-beta); newer names the server lists work as they are. A server that speaks a newer contract is refused, never read half-understood: ClientTooOldError (contract, supported), saying to pip install -U glyphh.

Every call that runs long is a job, waited for with its progress unless wait=False. Every write carries an Idempotency-Key, so the client sends again what is safe to: a read, or a write, while Ada is unreachable for a moment (E_UNAVAILABLE, E_TIMEOUT, a 502 to 504), and anything refused with 429, with backoff and Retry-After, for up to Ada(retry_deadline=) seconds (default 30; 0: never).

SDK 3.0's calls still work: Model.record, query, facts, probabilities, learn and call(function, inputs) go through POST /v1/runs and answer a Result (run_id, status, data, ...). The cloud answers every run at once, so a decision never waits for input: it says ask.

The API and its answers' shapes are in contract/contract.json. Pin glyphh>=3: versions up to 2.6.7 are a different, older library.
