Ultimately its about marketing and most stoners/growers arent exactly nerds who care about scientific accuracy. As a nerd my suggestion would be to have an actual lexicon attaching each terp +pheno to a specific word and append the growers last name/company name. force the industry to standardize. I think its fine to have strains like “spicey lemon Smith” as long as each of those words is riggerously attached to a specific meaning like spice is the cinnamony terp, lemon is limoline, Smith is company grower name.

All crap nondescript hype words like “ak” “og” “kush” “diesel” go right in the fucking bin IMO.

Of course this is pure theory crafting what if. You and I both know 99% of stoners dont actually care about name accuracy enough to make the industry self-police. as long as it gets them where they want. anyone who does care about exacts buys based off lab testing result data sheets.

What happened next did you break into the one big house, smoke it up, then got indoctrinated?

I don’t have a lot of knowledge on the topic but happy to point you in good direction for reference material. I heard about tensor layer offloading first from here a few months ago. In that post is linked another to MoE expert layer offloadingI highly recommend you read through both post. MoE offloading it was based off

The gist of the Tensor Cores strategy is Instead of offloading entire layers with --gpulayers, you use --overridetensors to keep specific large tensors (particularly FFN tensors) on CPU while moving everything else to GPU.

This works because:

• Attention tensors: Small, benefit greatly from GPU parallelization
• FFN tensors: Large, can be efficiently processed on CPU with basic matrix multiplication

You need to figure out which cores exactly need to be offloaded for your model looking at weights and cooking up regex according to the post.

Heres an example of a kobold startup flags for doing this. The key part is the override tensors flag and the regex contained in it

python ~/koboldcpp/koboldcpp.py --threads 10 --usecublas --contextsize 40960 --flashattention --port 5000 --model ~/Downloads/MODELNAME.gguf --gpulayers 65 --quantkv 1 --overridetensors "\.[13579]\.ffn_up|\.[1-3][13579]\.ffn_up=CPU"
...
[18:44:54] CtxLimit:39294/40960, Amt:597/2048, Init:0.24s, Process:68.69s (563.34T/s), Generate:56.27s (10.61T/s), Total:124.96s

The exact specifics of how you determine which tensors for each model and the associated regex is a little beyond my knowledge but the people who wrote the tensor post did a good job trying to explain that process in detail. Hope this helps.

I would recommend you get a cheap wattage meter that plugs inbetween wall outlet and PSU powering your cards for 10-15$ (the 30$ name brand kill-a-watts are overpriced and unneeded IMO). You can try to get rough approximations doing some math with your cards listed TPD specs added together but that doesn’t account for motherboard, cpu, ram, drives, so on all and the real change between idle and load. With a meter you can just kind of watch the total power draw with all that stuff factored in, take note of increase and max out as your rig inferences a bit. Have the comfort of being reasonably confident in the actual numbers. Then you can plug the values in a calculation

I have not tried any models larger than very low quant qwen 32b . My personal limits for partial offloading speeds are 1 tps and the 32b models encroach on that. Once I get my vram upgraded from 8gb to 16-24gb ill test the waters with higher parameters and hit some new limits to benchmark :) I haven’t tried out MoE models either, I keep hearing about them. AFAIK they’re popular with people because you can do advanced partial offloading strategies between different experts to really bump the token generation. So playing around with them has been on my ml bucket list for awhile.

Oh, I LOVE to talk, so I hope you don’t mind if I respond with my own wall of text :) It got really long, so I broke it up with headers.

TLDR: Bifurcation is needed because of how fitting multiple GPUs on one PCIe x16 lane works and consumer CPU PCIe lane management limits. Context offloading is still partial offloading, so you’ll still get hit with the same speed penalty—with the exception of one specific advanced partial offloading inference strategy involving MoE models.

CUDA

To be clear about CUDA, it’s an API optimized for software to use NVIDIA cards. When you use an NVIDIA card with Kobold or another engine, you tell it to use CUDA as an API to optimally use the GPU for compute tasks. In Kobold’s case, you tell it to use cuBLAS for CUDA.

The PCIe bifurcation stuff is a separate issue when trying to run multiple GPUs on limited hardware. However, CUDA has an important place in multi-GPU setups. Using CUDA with multiple NVIDIA GPUs is the gold standard for homelabs because it’s the most supported for advanced PyTorch fine-tuning, post-training, and cutting-edge academic work.

But it’s not the only way to do things, especially if you just want inference on Kobold. Vulkan is a universal API that works on both NVIDIA and AMD cards, so you can actually combine them (like a 3060 and an AMD RX) to pool their VRAM. The trade-off is some speed compared to a full NVIDIA setup on CUDA/cuBLAS.

PCIe Bifurcation

Bifurcation is necessary in my case mainly because of physical PCIe port limits on the board and consumer CPU lane handling limits. Most consumer desktops only have one x16 PCIe slot on the motherboard, which typically means only one GPU-type device can fit nicely. Most CPUs only have 24 PCIe lanes, which is just enough to manage one x16 slot GPU, a network card, and some M.2 storage.

There are motherboards with multiple physical x16 PCIe slots and multiple CPU sockets for special server-class CPUs like Threadrippers with huge PCIe lane counts. These can handle all those PCIe devices directly at max speeds, but they’re purpose-built server-class components that cost $1,000+ USD just for the motherboard. When you see people on homelab forums running dozens of used server-class GPUs, rest assured they have an expensive motherboard with 8+ PCIe x16 slots, two Threadripper CPUs, and lots of bifurcation. (See the bottom for parts examples.)

Information on this stuff and which motherboards support it is spotty—it’s incredibly niche hobbyist territory with just a couple of forum posts to reference. To sanity check, really dig into the exact board manufacturer’s spec PDF and look for mentions of PCIe features to be sure bifurcation is supported. Don’t just trust internet searches. My motherboard is an MSI B450M Bazooka (I’ll try to remember to get exact numbers later). It happened to have 4x4x4x4 compatibility—I didn’t know any of this going in and got so lucky!

For multiple GPUs (or other PCIe devices!) to work together on a modest consumer desktop motherboard + CPU sharing a single PCIe x16, you have to:

1. Get a motherboard that allows you to intelligently split one x16 PCIe lane address into several smaller-sized addresses in the BIOS
2. Get a bifurcation expansion card meant for the specific splitting (4x4x4x4, 8x8, 8x4x4)
3. Connect it all together cable-wise and figure out mounting/case modification (or live with server parts thrown together on a homelab table)

A secondary reason I’m bifurcating: the used server-class GPU I got for inferencing (Tesla P100 16GB) has no display output, and my old Ryzen CPU has no integrated graphics either. So my desktop refuses to boot with just the server card—I need at least one display-output GPU too. You won’t have this problem with the 3060. In my case, I was planning a multi-GPU setup eventually anyway, so going the extra mile to figure this out was an acceptable learning premium.

Bifurcation cuts into bandwidth, but it’s actually not that bad. Going from x16 to x4 only results in about 15% speed decrease, which isn’t bad IMO. Did you say you’re using a x1 riser though? That splits it to a sixteenth of the bandwidth—maybe I’m misunderstanding what you mean by x1.

I wouldn’t obsess over multi-GPU setups too hard. You don’t need to shoot for a data center at home right away, especially when you’re still getting a feel for this stuff. It’s a lot of planning, money, and time to get a custom homelab figured out right. Just going from Steam Deck inferencing to a single proper GPU will be night and day. I started with my decade-old ThinkPad inferencing Llama 3.1 8B at about 1 TPS, and it inspired me enough to dig out the old gaming PC sitting in the basement and squeeze every last megabyte of VRAM out of it. My 8GB 1070 Ti held me for over a year until I started doing enough professional-ish work to justify a proper multi-GPU upgrade.

Offloading Context

Offloading context is still partial offloading, so you’ll hit the same speed issues. You want to use a model that leaves enough memory for context completely within your GPU VRAM. Let’s say you use a quantized 8B model that’s around 8GB on your 12GB card—that leaves 4GB for context, which I’d say is easily about 16k tokens. That’s what most lower-parameter local models can realistically handle anyway. You could partially offload into RAM, but it’s a bad idea—cutting speed to a tenth just to add context capability you don’t need. If you’re doing really long conversations, handling huge chunks of text, or want to use a higher-parameter model and don’t care about speed, it’s understandable. But once you get a taste of 15-30 TPS, going back to 1-3 TPS is… difficult.

MoE

Note that if you’re dead set on partial offloading, there’s a popular way to squeeze performance through Mixture of Experts (MoE) models. It’s all a little advanced and nerdy for my taste, but the gist is that you can use clever partial offloading strategies with your inferencing engine. You split up the different expert layers that make up the model between RAM and VRAM to improve performance—the unused experts live in RAM while the active expert layers live in VRAM. Or something like that.

I like to talk (in case you haven’t noticed). Feel free to keep the questions coming—I’m happy to help and maybe save you some headaches.

Oh, in case you want to fantasize about parts shopping for a multi-GPU server-class setup, here are some links I have saved for reference. GPUs used for ML can be fine on 8 PCI lanes (https://www.reddit.com/r/MachineLearning/comments/jp4igh/d_does_x8_lanes_instead_of_x16_lanes_worsen_rtx/)

A Threadripper Pro has 128 PCI lanes: (https://www.amazon.com/AMD-Ryzen-Threadripper-PRO-3975WX/dp/B08V5H7GPM)

You can get dual sWRX8 motherboards: (https://www.newegg.com/p/pl?N=100007625+601362102)

You can get a PCIe 4x expansion card on Amazon: (https://www.amazon.com/JMT-PCIe-Bifurcation-x4x4x4x4-Expansion-20-2mm/dp/B0C9WS3MBG)

All together, that’s 256 PCI lanes per machine, as many PCIe slots as you need. At that point, all you need to figure out is power delivery.

Thanks for being that guy, good to know. Those specific numbers shown were just done tonight with DeepHermes 8b q6km (finetuned from llama 3.1 8b) with max context at 8192, in the past before I reinstalled I managed to squeeze ~10k context with the 8b by booting without a desktop enviroment. I happen to know that DeepHermes 22b iq3 (finetuned from mistral small) runs at like 3 tps partially offloaded with 4-5k context.

Deephermes 8b is the fast and efficient general model I use for general conversation, basic web search, RAG, data table formatting/basic markdown generation, simple computations with deepseek r1 distill reasoning CoT turned on.

Deephermes 22b is the local powerhouse model I use for more complex task requiring either more domain knowledge or reasoning ability. For example to help break down legacy code and boilerplate simple functions for game creation.

I have vision model + TTS pipeline for OCR scanning and narration using qwen 2.5vl 7b + outetts+wavtokenizer which I was considering trying to calculate though I need to add up both the llm tps and the audio TTS tps.

I plan to load up a stable diffusion model and see how image generation compares but the calculations will probably be slightly different.

I hear theres one or two local models floating around that work with roo-cline for the advanced tool usage, if I can find a local model in the 14b range that works with roo even if just for basic stuff it will be incredible.

Hope that helps inform you sorry if I missed something.

No worries :) a model fully loaded onto 12gb vram on a 3060 will give you a huge boost around 15-30tps depending on the bandwidth throughput and tensor cores of the 3060. Its really such a big difference once you get a properly fit quantized model your happy with you probably won’t be thinking of offloading ram again if you just want llm inferencing. Check to make sure your motherboard supports pcie burfurcation before you make any multigpu plans I got super lucky with my motherboard allowing 4x4x4x4 bifuraction for 4 GPUs potentially but I could have been screwed easy if it didnt.

I just got second PSU just for powering multiple cards on a single bifurcated pcie for a homelab type thing. A snag I hit that you might be able to learn from: PSUs need to b turned on by the motherboard befor e being able to power a GPU. You need a 15$ electrical relay board that sends power from the motherboard to the second PSU or it won’t work.

Its gonna be slow as molasses partially offloaded onto regular ram no matter what its not like ddr4 vs ddr3 is that much different speed wise. It might maybe be a 10-15% increase if that. If your partially offloading and not doing some weird optimized MOE type of offloading expect 1-5token per second (really more like 2-3).

If youre doing real inferencing work and need speed then vram is king. you want to fit it all within the GPU. How much vram is the 3060 youre looking at?

I dry herb vaporize legal thca flower. Gotta get it from a reputable lab testing supplier and look at percentages and terp profiles. High wise its the same thing.

Thank you for deciding to engage with our community here! You’re in good company.

Kobold just released a bunch of tools for quant making you may want to check out.

Kcpp_tools

I have not made my own quants. I usually just find whatever imatrix gguf bartowlski or the other top makers on HF release.

I too am in the process of upgrading my homelab and opening up my model engine as a semi public service. The biggest performance gains ive found are using CUDA and loading everything in vram. So far just been working with my old nvidia 1070ti 8gb card.

Havent tried vllm engine just kobold. I hear good things about vllm it will be something to look into sometime. I’m happy and comfortable with my model engine system as it got everything setup just the way I want is but I’m always open to performance optimization.

If you havent already try running vllm with its CPU nicencess set to highest priority. If vllm can use flash attention try that too.

I’m just enough of a computer nerd to get the gist of technical things and set everything up software/networking side. Bought a domain name, set up a web server and hardened it. Kobolds webui didnt come with https SSL/TLS cert handling so I needed to get a reverse proxy working to get the connection properly encrypted.

I am really passionate about this even though so much of the technical nitty gritty under the hood behind models goes over my head. I was inspired enough to buy a p100 Tesla 16gb and try shoving it into an old gaming desktop which is my current homelab project. I dont have a lot of money so this was months of saving for the used server class GPU and the PSU to run it + the 1070ti 8gb I have later.

The PC/server building hardware side scares me but I’m working on it. I’m not used to swapping parts out at all. when I tried to build my own PC a decade ago it didnt last long before something blew so there’s a bit of residual trauma there. I’m worried about things not fit right in the case, or destroying something or the the card not working and it all.

Those are unhealthy worries when I’m trying to apply myself to this cutting edge stuff. I’m really trying to work past that anxiety and just try my best to install the stupid GPU. I figure if I fail I fail thats life it will be a learning experience either way.

I want to document the upgrade process journey on my new self hosted site. I also want to open my kobold service to public use by fellow hobbyist. I’m not quite confident in sharing my domain on the public web though just yet I’m still cooking.

Right now THCA mail-order is under fire from goons in house and senate so if your gonna order on bulk legally may want to do it soon the lawmaking could go either way. I recommend eight horse hemp for cheap mid bulk and wnc-cbd for the top shelf premium

Have you by chance checked out kobold.cpp lite webUI? It allows some of what your asking for like RAG for worldbuilding, adding images for the llm to describe to add into the story, easy editing of input and output, lots of customization in settings. I have a public instance of kobold webui setup on my website and I’m cool with allowing fellow hobbyist using my compute to experiment with things. If your interested in trying it out to see if its more what youre looking for, feel free to send me a pm and I’ll send you the address and a api key/password.

In an ideal work what exactly would you want an AI integrated text editor to do? Depending on what you need to have happen in your workflow you can automate copy pasting and automatic output logging with python scripts and your engines api.

Editing and audiing stories isnt that much different from auditing codebases. It all boils down to the understanding and correct use of language to convey abstraction. I bet tweaking some agebic personalities and goals in vscode+roo could get you somewhere

Yesss lol 🫠😵‍💫🤭

Aaaa that looks like some dry ass ground trim if its even bud at all it looks like a cookibg spice the grains are very long and narrow

Good to hear you figured it out with router settings. I’m also new to this but got all that figured out this week. As other commenters say I went with a reverse proxy and configured it. I choose caddy over nginx for easy of install and config. I documented just about every step of the process. I’m a little scared to share my website on public fourms just yet but PM me ill send you a link if you want to see my infrastructure page where I share the steps and config files.
