	36	+	## Connect a provider
32	37
33	38		1. Open the workspace's Integrations page. You need to be an owner.
34		−	2. Under Model provider, choose Anthropic or Your own endpoint.
35		−	3. For Anthropic, paste an API key. For an endpoint, give its base URL
36		−	without `/v1`, its key if it needs one, and whether the key goes in
37		−	`x-api-key` or `Authorization: Bearer`.
38		−	4. Connect, then Test: g1t asks the provider to list its models with
39		−	the key. An endpoint that does not list models is checked on the first
40		−	run instead.
	39	+	2. Under Model providers, choose one, and give its key (and address, for
	40	+	an endpoint).
	41	+	3. Connect. g1t checks the key at once and lists the provider's models.
	42	+	Test checks it again later.

	46	+	## Choose which model does which work
	47	+
	48	+	Under Which model does which work, each kind of work has a choice:
41	49

44	57
45		−	### Choosing the model
	58	+	Each can go to g1t's models, or to any of your providers on any of its
	59	+	models. An Anthropic provider also offers g1t's choice of Claude model,
	60	+	which runs g1t's pick for that kind of work on your key. For example: make
	61	+	changes on Claude through your Anthropic key, review on GPT through your
	62	+	OpenAI key, and catch up on a small model through OpenRouter.
46	63
47		−	Nobody picks a model when assigning work; g1t routes each kind of work to
48		−	the model that suits it, and with your own Anthropic key the same models
49		−	run on your account. If your endpoint names models its own way, set
50		−	Model on the connection and every kind of work uses it.
	64	+	Save routing, and the next runs use it. Without any routing, work goes
	65	+	to g1t's models where they are open to the workspace, and otherwise to the
	66	+	first provider you connected.

54		−	## Your key never reaches a sandbox
	70	+	## What it costs
55	71
	72	+	On your own providers, they bill you for the models, and g1t charges your
	73	+	credit a flat $0.10 per run for the sandbox and orchestration. A
	74	+	change, a review, a revision, a catch-up and a plan are each a run. The
	75	+	statement marks these runs "on your own model provider" and names the
	76	+	model and provider; the Usage page shows what they cost at the provider,
	77	+	as the harness estimated it, beside what g1t charged. See
	78	+	[Usage and billing](/guides/usage-and-billing/).
	79	+
	80	+	Workspaces still need credit to start agents, for the fee.
	81	+
	82	+	## Your keys never reach a sandbox
	83	+
56	84		An agent works in a sandbox with internet access, on code and text that

60	88		1. When a run starts, g1t gives the sandbox a token for that run only.
61	89		2. The sandbox sends its model requests to `https://models.g1t.sh` with that
62	90		token in place of a key.

65	94
66	95		The token stops working when the run ends (three hours at most), or at once
