What is image-models?

A set of instructions for choosing image-generation and background-removal models for img-gen-mcp. It covers providers such as OpenRouter, OpenAI, Gemini, and local systems, along with supported model identifiers.

Use it when configuring img-gen-mcp, selecting an image model, comparing provider options, or validating supported model names.

It helps agents choose a suitable image or background-removal backend instead of guessing which provider and model to use.

Token cost

What it costs to keep this loaded

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	$0.00032	$0.00868
Opus 5	$0.00016	$0.00434
Sonnet 5	$0.00006	$0.00174

Security

Grade A, and why

image-models scanned grade A with 0 findings 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 10d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Image Models And Backends

Use this skill when selecting or validating image generation models, local provider backends, and background-removal backends for img-gen-mcp.

Supported OpenRouter image models

Prefer these slugs when prompting OpenRouter image generation:

microsoft/mai-image-2.5
openai/gpt-image-1
openai/gpt-5-image-mini
openai/gpt-5.4-image-2
google/gemini-2.5-flash-image
google/gemini-2.5-flash-image-preview
google/gemini-3-pro-image-preview
x-ai/grok-imagine-image-quality
bytedance-seed/seedream-4.5
sourceful/riverflow-v2.5-fast:free
sourceful/riverflow-v2.5-fast
sourceful/riverflow-v2.5-pro
sourceful/riverflow-v2-fast
sourceful/riverflow-v2-pro
recraft/recraft-v4.1-utility
recraft/recraft-v4.1-vector
recraft/recraft-v4.1-utility-pro
recraft/recraft-v4.1-pro-vector
recraft/recraft-v3
black-forest-labs/flux.2-pro
black-forest-labs/flux.2-flex

Model notes

microsoft/mai-image-2.5 is a strong default for polished photorealistic output.
x-ai/grok-imagine-image-quality is image-only and is good for realistic, prompt-faithful results.
openai/gpt-5-image-mini is useful when lower latency is preferred.
sourceful/riverflow-* models are often useful for stylized or prompt-following generation.
recraft/* models are useful for logo/vector-style work.
provider=auto can infer the backend from the model slug for common OpenAI, Gemini, OpenRouter, and local wrapper families.

Discovery tools

Use list_image_models to inspect provider families, defaults, and output directories.
Use get_provider_status to check which providers are configured, the active defaults, and local bootstrap hints.
Use get_model_capabilities to see which providers can generate, edit, batch, or use local endpoints.

Workflow helpers

Use submit_task and get_task when a client prefers polling instead of waiting synchronously.
Use batch_generate_image when you want multiple variants from a single prompt.

image-models is a skill published in the GitHub repository jgkme/img-gen-mcp (2 stars, last pushed 2mo ago), licensed MIT. It adds 32 tokens to every session and 868 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
