Say per AI whether its model sees pictures - #1177
Review just this PR's changes:its own commits. GitHub's diff here also includes #1161 and #1155, which it's stacked on, until they merge.
Stacked on #1161 (which is on #1155). Only the last two commits are this PR: the claim and Say per AI whether its model sees pictures. I'll rebase it as those merge.
What changes
Each API backend gets vision = auto | yes | no in [[ai.backends]], and the CLI gets ai vision <name> [auto|yes|no]. With no value, ai vision shows the setting, what the server said, and which probe said it. This is the first half of the R5.4 line about pictures. Nothing shows a model a picture yet: attaching the check's screenshot and the person's pictures is the next step, and needs #1159 and #1175 too.
Auto asks the server. It uses the same Fetch/Server seam as the context window (#1155), through a new SightProbe trait in crates/ai/src/sight.rs and a ChatModel::sees_pictures hook. Probes, first answer wins:
Probe

Anthropic
a claude- model
yes
Remote services are asked only through their list. A model nobody answers for is treated as blind.
A guard I found live, also pushed to #1155 as 3806c8b. llama-swap starts a model for a /props?model= request, not only for the upstream route. Asking about an unloaded model whose list entry said nothing fell through to the llama.cpp probe, and that unloaded the model in use and loaded the other one. The window probe had the same hole for any model listed without a context length. Now a model llama-swap lists but hasn't loaded is asked about only through the list. There's a pitfall entry for it.
Tests
Unit tests run on the recorded shapes from a live llama-swap server, plus each server's yes, no and nothing answers and hostile shapes.
A test checks that an unloaded llama-swap model's /props?model= isn't asked, even though it would answer.
I broke seven rules one at a time and a test failed each time: the list's yes-only rule, Auto's mapping, the alias/loaded lookup, Ollama's no, remote-only, and the llama-swap guard in both probes.
A CLI test covers ai vision (show, set, a refused value, Auto not written, an unknown name).
512 tests pass in craft-anything-ai and the CLI tests pass. clippy, fmt, layers, locks and secrets are clean.
Live
On Linux, against a llama-swap server on my machine (2× RTX 6000, so I can test both high-end and low-end models):
A loaded Qwen model, and one of its aliases, read as seeing through llama-swap's upstream /props in about 28 ms.
A loaded Gemma model read as seeing through the model list.
Unloaded models read as unknown, and the loaded model was the same before and after.
Not run live: Ollama, LM Studio, and a plain llama.cpp server.
Left for later (on the roadmap)
The Settings → AI dropdown. It lands with attachment, so the choice does something when it appears.
Asking again after the first reply. Under Auto, a model llama-swap hasn't loaded yet reads as blind for the whole conversation, because asking earlier would start it.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The change adds per-backend context-budget, tool-list, and vision settings. It discovers server context windows and picture support, applies context and tool-selection rules during agent builds, and adds CLI and desktop controls with tests and documentation.
Configuration adds ToolList and Vision. Model interfaces and server probes expose context-window and picture-capability data. AiHub adds setting updates and capability queries.
Context budgets and builder tool selection crates/ai/src/agent.rs, crates/ai/src/rebuild/*, crates/ai/src/tests.rs
Agent builds query context windows, calculate budgets, and select builder tools per backend. The system prompt changes when the selected tool list changes. Tests cover budgeting, window queries, and tool selection.
The CLI and desktop add context-budget and tool-list controls. The CLI also adds vision controls. The desktop requests server windows asynchronously. Tests and documentation cover the settings and related behavior.

A missing provider key may appear as an unknown context window rather than an actionable configuration error. This is a bounded diagnostic issue, not a blocker to using the other settings.

Share one context-budget parser between the CLI and the desktop app.
The CLI Context arm and builders::context_budget in crates/ui-egui/src/builders.rs parse the same input with different rules:
The desktop parser strips spaces, commas and underscores. The CLI strips only commas and underscores. ai context Box "390 000" fails in the CLI, but the same text works in Settings.
The CLI matches auto case-sensitively. ai context Box Auto fails. ai tools and ai vision use case-insensitive parse functions, so the three commands behave differently.
Put one parser in the craft_anything_ai crate and call it from both places. This also follows the roadmap rule that logic reachable from the UI belongs behind the headless API.
♻️ Proposed change in the CLI arm
- let budget = match tokens.trim() {- "auto" => None,- t => match t.replace(['_', ','], "").parse::<u64>().ok().filter(|n| *n > 0) {- Some(n) => Some(n),- None => {- let e = ToolError::invalid(format!("{t:?} isn't a number of tokens.")).with_remediation("Use a whole number such as 390000, or auto.");- return fail(&e, f);- }- },- };+ let budget = match craft_anything_ai::parse_context_budget(tokens) {+ Some(b) => b,+ None => {+ let e = ToolError::invalid(format!("{:?} isn't a number of tokens.", tokens.trim())).with_remediation("Use a whole number such as 390000, or auto.");+ return fail(&e, f);+ }+ };
Add parse_context_budget(text: &str) -> Option<Option<u64>> to crates/ai. It must accept auto (any case) and empty text as Some(None), and strip spaces, commas and underscores before parsing a positive u64. Then make builders::context_budget call it.

852-854: Trivial · Maintainability & Code Quality · Low value
Build the model once, and the Auto vision path will not honor ssh_host locality.
server_window and vision call build_model. For OpenaiCompatible backends, build_model does not open a tunnel when ssh_host is empty. That is correct. When ssh_host is set, both functions skip the build. That is also correct.
One narrow gap remains. build_model returns an error when a hosted provider has no key, and .ok() discards that error. The CLI then reports "window unknown" with no reason. The user cannot tell a missing key from a server that does not name a window.
Return the build error as a note, or add a reason field to ServerWindow. This is a recommended improvement, not a blocker.

Add the plan for local models that can do more than the lean defaults
assume: the context window read from the server, an Auto/Lean/Full tool
list per AI, honest prompts for builders that can't see pictures, and
pictures for models that can. The first line is claimed.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A model on this computer or its network was budgeted at 24k tokens
whatever it could hold, and the real window was only learned from a
refusal, which never came once we trimmed first. Before a backend's first
request, and once more after it while the server hasn't said, the agent
now asks the server for the window it has loaded: the model list
(context_length, max_model_len, meta.n_ctx), llama-swap's upstream route
for a loaded model, llama.cpp's /props, LM Studio's loaded_context_length
and Ollama's /api/ps. Three quarters of it is a local model's budget; it
only lowers a paid service's. Each server is a WindowProbe, so a fork can
add one.
context_tokens gets a field in Settings -> AI (Auto by default) and
`ai context <name> <tokens|auto>` in the CLI.

…ings
The gate skipped every service off this network but OpenRouter, while
its comment and the docs said they were asked through their model list.
OpenAI-compatible services now are (official OpenAI and Gemini, whose
lists say no window, still aren't), and Groq's `context_window` field is
read. Adds tests for the hub's set_context_tokens, `ai context` and the
Settings field.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The llama-swap upstream route and Ollama 0.40.15 were asked live; note
Ollama's 4096-token default under the line about setting a server's size.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The budget was a bare text box that wrapped away from its label and
didn't say what Auto meant. It is now a dropdown on its own line (Auto,
8k to 1M, Custom… for any number, so nothing is capped), and under it a
note worked out with the agent loop's own rule from the window the
server names: "Auto: 393,216 tokens of the server's 524,288", or
"196,608 will be used: the server holds 262,144". `ai context` shows
the same window and budget. Strings are in all 13 catalogs.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The 150k cap for a paid service's Auto budget was applied before the person's own budget was compared with the window, so a 390k budget became 150k. Also escape a pipe that split a STATUS table row.

llama-swap starts a model for a /props?model= request too, so the llama.cpp probe swapped out the loaded model whenever the list gave no window for an unloaded one.

Ollama and LM Studio name their window only once the model is loaded, and Settings kept the first answer for the whole session. Opening Settings now forgets answers without a window. The roadmap gets the ssh case. Both found by CodeRabbit.

Paced (from storytold#1469) wraps a backend with requests_per_minute, and it
didn't pass context_window on, so a paced backend's Auto budget never
saw the window its server names. It forwards it now, as Tunneled does.

Every builder on a local model got the lean list (storytold#417) and a system
prompt without the memory steps, whatever its window, so a model with a
262k or 512k window built with the same cut-down tools as a 4k one.
Each API backend now has a tool list: `tools` in [[ai.backends]],
Settings → AI "Tools for building", and `ai tools <name>`. Lean is the
building list, Full is every tool and the memory steps. Auto, the
default, is Full on a paid service, and on a local model Full when the
conversation's budget is FULL_TOOLS_BUDGET (49,152: a 64k window less
its quarter) or more, else Lean. With no window known a local model
stays lean, as before.
The loop now asks the server for its window before choosing, and
chooses again before each turn, rewriting the system prompt when the
list changes (Ollama names its window only once the model is loaded).
The choice is journaled as `tools`. Chats keep every tool.
Stacked on storytold#1155, which reads the server's window.

Only the large-model half of the live-run item was run; the lean run on a small model gets its own open line.

Settings showed "(the lean list until its server says it holds more)" for a
local AI on Auto tools with no window yet, even when its saved context budget
was below the full list's: that budget stays lean whatever the server says.
`ServerWindow::lean_until_told` asks whether a server naming a large window
would change the choice, and the note follows it.

vision = auto | yes | no on each API backend, and ai vision to show and set it. Auto asks the server: a model list's input modalities, llama-swap's upstream /props for a loaded model, llama.cpp's /props modalities, LM Studio's model type and Ollama's capabilities; a Claude model sees. Nothing said is treated as blind.
Carries storytold#1155's guard (asking llama-swap about an unloaded model only through its list), which the sight probe needs too.

sees_pictures read the model id as written, so anthropic/claude-… and anthropic.claude-… (gateway ids) said nothing and were treated as blind. It now strips them the way effort_for does, through one helper.

Paced didn't pass sees_pictures on, so under Vision Auto a backend with
requests_per_minute was taken as blind, even Claude. It forwards it now,
as Tunneled does.

Review just this PR's changes: its own commits. GitHub's diff here also includes #1161 and #1155, which it's stacked on, until they merge.
Stacked on #1161 (which is on #1155). Only the last two commits are this PR: the claim and
Say per AI whether its model sees pictures. I'll rebase it as those merge.What changes
Each API backend gets
vision = auto | yes | noin[[ai.backends]], and the CLI getsai vision <name> [auto|yes|no]. With no value,ai visionshows the setting, what the server said, and which probe said it. This is the first half of the R5.4 line about pictures. Nothing shows a model a picture yet: attaching the check's screenshot and the person's pictures is the next step, and needs #1159 and #1175 too.Auto asks the server. It uses the same
Fetch/Serverseam as the context window (#1155), through a newSightProbetrait incrates/ai/src/sight.rsand aChatModel::sees_pictureshook.

A model nobody answers for is treated as blind.
A guard I found live, also pushed to #1155 as
3806c8b. llama-swap starts a model for a/props?model=request, not only for the upstream route. Asking about an unloaded model whose list entry said nothing fell through to the llama.cpp probe, and that unloaded the model in use and loaded the other one. The window probe had the same hole for any model listed without a context length. Now a model llama-swap lists but hasn't loaded is asked about only through the list. There's a pitfall entry for it.Tests
/props?model=isn't asked, even though it would answer.ai vision(show, set, a refused value, Auto not written, an unknown name).craft-anything-aiand the CLI tests pass. clippy, fmt, layers, locks and secrets are clean.Live
