	21	+	## Auto
21	22
	23	+	On g1t's models you do not have to pick a model. Auto, the default,
	24	+	sends each job to the least costly model that can do it, from three tiers:
	25	+	fast (Claude Haiku 4.5 today), standard (Claude Sonnet 5.5) and
	26	+	most capable (Claude Opus 5.5). It decides by the kind of job, the
	27	+	size of the change it reads, the issue's labels, whether the last attempt
	28	+	at the same work failed, and what has worked in the repository before:
	29	+
	30	+	- Catching up, answering a question and reviewing a small change that
	31	+	touches no sensitive path start on the fast model.
	32	+	- Making and revising changes, planning, and most reviews start on the
	33	+	standard model.
	34	+	- A review of a very large change, work on an issue labelled
	35	+	`architecture`, and work that failed twice in a row go to the most
	36	+	capable model. One failure moves the next attempt up one tier.
	37	+	- When the cheaper model finished nearly all of a repository's recent runs
	38	+	of the same kind, Auto moves that work down a tier there; when a model
	39	+	keeps failing, up.
	40	+
	41	+	Every run says which model it used and why, in one line on its run and in
	42	+	its pull request's session, such as *Used a fast model (Claude Haiku 4.5):
	43	+	small change, 3 files and 80 lines.* The full rules are in
	44	+	[which model runs](/guides/working-with-g1t/#which-model-runs).

79		−	which runs g1t's large-tier model, Claude Sonnet 5.5 today, on your key.
80		−	Routing between tiers by the size of the work is only for g1t's hosted

	102	+	models.
	103	+
	104	+	- On g1t's models, choose Auto (the default), or a tier for every
	105	+	run of that kind: Fast, Standard or Most capable. A run on a
	106	+	chosen tier says the workspace chose it.
	107	+	- On an Anthropic provider, leave the model empty for g1t's choice of
	108	+	Claude: Auto picks the tier's model for each job, as on g1t's models, on
	109	+	your key. Name a model to run that one every time.
	110	+	- On any other provider, name the model.
	111	+
	112	+	For example: make changes on Claude through your Anthropic key, review on
	113	+	GPT through your OpenAI key, catch up on g1t's models on Fast, and plan on
	114	+	Most capable.

⋯
90	121
91	122		## What it costs
92	123
93		−	Your providers bill you for the models. g1t charges only each run's
94		−	[sandbox time](/guides/usage-and-billing/#sandbox-time), at what it costs
95		−	g1t plus 20%, by the second. A change, a review, a revision, a catch-up
96		−	and a plan each run in a sandbox, and each sandbox is a line on the
97		−	statement. See [Usage and billing](/guides/usage-and-billing/).
	124	+	On g1t's models, each run is charged the model at the provider's price
	125	+	(what AI Gateway priced its requests at, with no markup), the agent rate
	126	+	on its tokens, and its sandbox time. Auto keeps the first of those down:
	127	+	the fast model costs about half what the standard one does, and the most
	128	+	capable up to twice as much, so most of what it saves comes from sending small
	129	+	jobs to the fast model and from finishing hard ones instead of retrying
	130	+	them on the same model.
98	131
99		−	That sandbox time counts toward the workspace's usage limit like any
100		−	other.
	132	+	On your own providers, they bill you for the models. g1t charges each
	133	+	run's [sandbox time](/guides/usage-and-billing/#sandbox-time), at what it
	134	+	costs g1t plus 20%, by the second, and the
	135	+	[agent rate](/guides/usage-and-billing/#the-agent-rate) on the tokens the
	136	+	run used, from Oct 22, 2026: $0.25 per million, as on g1t's models. Tokens
	137	+	are counted by g1t's model proxy as answers pass, and by the agent in the
	138	+	sandbox; the more of the two is charged. On Usage it is the line
	139	+	Agent rate, your own model key, with its tokens weighted as the
	140	+	pricing page says.
	141	+
	142	+	Both count toward the workspace's usage limit like any other charge.
	143	+	Usage also shows the agent's tokens by model.

116	159		output, and cache reads and writes) and counts them for the run, under the
117		−	person it was for. Those counts are for usage views; they never change what
118		−	a run is charged.
	160	+	person it was for. They show on Usage by model, and the
	161	+	[agent rate](/guides/usage-and-billing/#the-agent-rate) is charged on them.
	162	+	On g1t's models, the model itself is charged at what AI Gateway priced it
	163	+	at, never from these counts.

	245	+	on g1t's models and on your own model key alike:
	246	+
	247	+	1. g1t's model proxy counts each answer's tokens as it passes: input,
	248	+	output, and prompt-cache reads and writes. The sandbox reports what its
	249	+	agent counted too, and the rate is charged on the more of the two.
	250	+	2. Each kind of token counts at its weight. Today every token counts
	251	+	once: input ×1, output ×1, cache reads ×1, cache writes ×1. The weights
	252	+	are on [g1t.sh/pricing](https://g1t.sh/pricing) under the rate, and a
	253	+	change to them is a dated price change like any other.
	254	+	3. The run is charged when it reports, and again for tokens counted after
	255	+	that, never twice for the same token.
237	256
	257	+	On the Usage page the agent rate's lines count weighted tokens and name
	258	+	the weights: Agent rate for runs on g1t's models, and **Agent rate, your

238	261		The charge goes to the workspace that owns the repository, whoever

	443	+	You do not have to pick one. You assign the work to `g1t`, the way you
	444	+	would assign an issue to a colleague, and Auto routes each job to the
	445	+	least costly model that can do it, from three tiers:
446	446
447		−	\| Tier \| Model today \|
448		−	\| --- \| --- \|
449		−	\| Small \| Claude Haiku 4.5 \|
450		−	\| Large \| Claude Sonnet 5.5 \|
	447	+	\| Tier \| Model today \| For \|
	448	+	\| --- \| --- \| --- \|
	449	+	\| Fast \| Claude Haiku 4.5 \| Small, well-bounded work \|
	450	+	\| Standard \| Claude Sonnet 5.5 \| Most changes and reviews \|
	451	+	\| Most capable \| Claude Opus 5.5 \| Hard work, and work that failed on the standard model \|
451	452
452		−	The work decides the tier:
	453	+	The job starts on its tier:
453	454
454		−	\| Work \| Tier \|
	455	+	\| Work \| Starts on \|
455	456		\| --- \| --- \|
456		−	\| Making a change for an issue, revising it, and answering a mention \| Large \|
457		−	\| Reviewing a pull request that changes at most 10 files and 200 lines, touches no sensitive path, and is not for an issue labelled `security` \| Small \|
458		−	\| Reviewing any other pull request, or one whose changed files g1t does not know yet \| Large \|
459		−	\| Catching up with `main` and resolving conflicts \| Small \|
460		−	\| Planning an outcome \| Small \|
461		−	\| Any of these again, after the last attempt at the same work failed or stopped at a guardrail cap \| Large \|
	457	+	\| Making a change for an issue, revising it, and taking over handed-on work \| Standard \|
	458	+	\| Answering a question asked of `@g1t` \| Fast \|
	459	+	\| Reviewing a pull request that changes at most 10 files and 200 lines and touches no sensitive path \| Fast \|
	460	+	\| Reviewing a pull request that changes more than 60 files or 3,000 lines \| Most capable \|
	461	+	\| Reviewing any other pull request, or one whose changed files g1t does not know yet \| Standard \|
	462	+	\| Catching up with the base branch and resolving conflicts \| Fast \|
	463	+	\| Planning an outcome \| Standard \|
	464	+
	465	+	Then, in this order:
462	466
	467	+	1. Labels on the issue. `architecture` sends the work to the most
	468	+	capable model. `security` keeps it off the fast one. `documentation`,
	469	+	`docs` and `typo` let a change or an answer start on the fast one.
	470	+	2. Failures. When the last attempt at the same work failed or stopped
	471	+	at a guardrail cap, the next goes one tier up; after two in a row, to
	472	+	the most capable. A revision counts each round before it. When the
	473	+	last attempt finished but left a change g1t had
	474	+	[low confidence](#how-sure-the-agent-is) in, the next goes one tier up.
	475	+	3. What worked here. g1t looks at the repository's last 20 runs of
	476	+	the same kind. When the tier below finished at least 9 in 10 of at
	477	+	least 5, the work goes down a tier; when this tier failed half of at
	478	+	least 5, it goes up. Work that touches a sensitive path or carries
	479	+	one of the labels above is never moved down.
	480	+
463	481		Sensitive paths are the ones that run, configure or guard things: CI
464	482		workflows, `.g1t/` and `.github/`, `CODEOWNERS`, secrets such as `.env`
465	483		and `.pem` files, and infrastructure such as Dockerfiles, Terraform and
466	484		`wrangler.*` files. They are the same paths that lower a change's
467	485		[confidence](#how-sure-the-agent-is).
468	486
469		−	The agent's own small background steps run on the small tier.
	487	+	The agent's own small background steps run on the fast tier.
470	488
471		−	Every session opens with a note naming the model that ran, and an agent's
472		−	review says which model wrote it, so what you got is always on the record.
473		−	When a better model for a tier appears, g1t changes the route and nothing
474		−	you have set up needs to change.
	489	+	Every run says which model it used and why, in one line: as the first
	490	+	step on its run, and at the top of its pull request's session. For
	491	+	example, *Used a fast model (Claude Haiku 4.5): small change, 3 files and
	492	+	80 lines.* An agent's review also says which model wrote it. When a better
	493	+	model for a tier appears, g1t changes the route and nothing you have set
	494	+	up needs to change.
475	495
	496	+	To choose instead of Auto, an owner picks Fast, Standard or **Most
	497	+	capable** for a kind of work under
	498	+	[which model does which work](/guides/models/#choose-which-model-does-which-work).
	499	+	Every run of that kind then uses it, and says the workspace chose it.
	500	+
476	501		A workspace that routes its work to [its own provider](/guides/models/)
477		−	is not routed by tier: its work runs on the model its route names.
	502	+	runs the model its route names. On an Anthropic key with no model named,
	503	+	Auto chooses the tier's Claude model, as on g1t's models.
478	504
479	505		A pull request g1t opens has `g1t` as its author and as its `agent` in the
480	506		API, and its commits are authored `g1t <g1t@users.noreply.g1t.sh>`.
