Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00044 | $0.03992 |
| Opus 5.5 | $0.00018 | $0.01597 |
| Sonnet 5.5 | $0.00009 | $0.00798 |
| Haiku 4.5 | $0.00004 | $0.00399 |
Grade A, and why
flux-txt2img 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 1mo 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.

Flux Text-to-Image Workflows
Overview
Flux is a guidance-distilled diffusion model family from Black Forest Labs. It uses a separate FluxGuidance node instead of KSampler CFG (which must always be 1.0). Three variants are available locally:
- Flux.1 Dev SRPO. Fine-tuned Flux.1 Dev with SRPO alignment. Uses DualCLIPLoader (T5XXL + CLIP-L). BF16 only.
- Flux 2 Klein 9B. Distilled Flux 2 variant. Uses single CLIPLoader (Qwen3-8B) +
flux2-vae.safetensors. Fast 4-step generation. - Flux 2 Turbo LoRA. Applied to Flux.1 Dev for 4-step generation.
Models
Flux.1 Dev SRPO
| Component | Node | Model | Notes |
|---|---|---|---|
| UNET | UNETLoader |
flux.1-dev-SRPO-BFL-bf16.safetensors |
22.7GB, BF16 only — FP8 produces broken results |
| CLIP | DualCLIPLoader (type=flux) |
clip_name1: t5xxl_fp8_e4m3fn.safetensors, clip_name2: clip_l.safetensors |
T5XXL (4.7GB) + CLIP-L (235MB) |
| VAE | VAELoader |
ae.safetensors |
Standard Flux VAE (320MB). Z-Image uses the same VAE architecture but different weights — its VAE is a separate file (z-image-ae.safetensors), not this one |
Flux 2 Klein 9B
| Component | Node | Model | Notes |
|---|---|---|---|
| UNET | UNETLoader |
bigLove_klein1.safetensors |
17.3GB, Klein 9B variant |
| CLIP | CLIPLoader (type=flux2) |
qwen_3_8b_fp8mixed.safetensors |
Qwen3-8B in text_encoders/ (8.3GB). Use flux2, NOT flux — both exist in the enum and flux fails at the sampler |
| VAE | VAELoader |
flux2-vae.safetensors |
Flux 2 specific VAE (321MB) |
Klein 9B vs Flux.1 Dev: Klein uses the Qwen3-8B text encoder (not T5XXL + CLIP-L). It has a different VAE (flux2-vae.safetensors). 9B distilled runs in 4 steps; 9B base needs ~50 steps at CFG 5.0. Fits in ~20GB VRAM with FP8.
Flux 2 Turbo LoRA (applied to Flux.1 Dev)
| Component | Node | Model | Notes |
|---|---|---|---|
| LoRA | LoraLoaderModelOnly |
flux2-turbo-lora.safetensors |
2.6GB, strength 1.0 |
| Alt LoRA | LoraLoaderModelOnly |
Flux2TurboComfyv2.safetensors |
Community variant, same size |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 1mo ago First seen · 296 lines · 44 tokens per session scan A 5583e0e25123
flux-txt2img is a skill published in the GitHub repository artokun/comfyui-mcp (871 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 3,992 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
