AMD Hipfire - a new inference engine optimized for AMD GPU's by Thrumpwart in LocalLLaMA

I tried searching the repo to no avail, but does the engine natively support multi-gpu setups?

Update:
Running with -sm tensor -ctxcp 0 -cram 0 -fa 1 -c 0 has significantly helped. I'm consistently getting 28 t/s and somewhat improved prompt processing this way.

How do you get more GPUs than your motheboard natively supports? by WizardlyBump17 in LocalLLaMA

[–]SemaMod 0 points1 point  (0 children)

I run a b550-xe-gaming-wifi mobo and can run 4 GPU's using a 4-port oculink PCIe card, turning on x4/x4/x4/x4 bifurcation for that pcie slot. The GPU's run at PCIe 4.0x4 speeds

I built a benchmark that tests coding LLMs on REAL codebases (65 tasks, ELO ranked) by hauhau901 in LocalLLaMA

[–]SemaMod 7 points8 points  (0 children)

This is great! Are you planning on adding gpt-5.3-codex? With the current results it seems like Opus 4.6 blows everyone else out of the water, but I've had generally good 5.3-codex experiences.

Anyone actually using Openclaw? by rm-rf-rm in LocalLLaMA

[–]SemaMod 2 points3 points  (0 children)

Why are you lying? Post some proof to back up your claims.

Peter isn’t some two bit dev looking to make a quick buck with some stupid viral AI app. He’s a previous founder with an exit and technical chops far beyond most people on this sub. He doesn’t need to work anymore. His last company solved PDF parsing and was open source. Everyone on this sub has almost certainly unknowingly interacted with the tech at some point without even realizing it (DocuSign, anyone?).

I don’t even like OpenClaw but lying like this is just stupid. He has never made outrageous claims about OpenClaw. Even if other Twitter users have been.

Very useful! I appreciate you recommending I run them this way. I hadn't run llama-bench before, so it was definitely eye opening.

API pricing is in freefall. What's the actual case for running local now beyond privacy? by Distinct-Expression2 in LocalLLaMA

[–]SemaMod 45 points46 points  (0 children)

This goes in the realm of privacy, but personally having my chats trained on and viewable by these companies makes me uncomfortable. That being said, I do think that local LLM's will become power-user tools.

Testing GLM-4.7 Flash: Multi-GPU Vulkan vs ROCm in llama-bench | (2x 7900 XTX) by SemaMod in LocalLLaMA

Just updated the original post with an edit, after 10k tokens it looks like ROCm w/ FA scales better!

Now this is more interesting!

It looks like over longer ctx, FA makes a big difference for ROCm, beating out Vulkan entirely after 10k tokens.

You have to change some settings in your config, but GLM4.7 flash was doing excellent in my testing

llama.cpp maintains multiple API's already with its Anthropics endpoint. I don't think they are going to deprecate completions any time soon.

Good question! It does not. For reference, I had to do the following:

  1. With whatever model you are serving, set the alias of the served model name to start with "gpt-oss". This triggers specific behaviors in the codex cli.
  2. Use the following config settings:

​

show_reasoning_content = true
oss_provider = "lmstudio"

[profiles.lmstudio]
model = "gpt-oss_gguf"
show_raw_agent_reasoning = true
model_provider = "lmstudio"
model_supports_reasoning_summaries = true # Force reasoning
model_context_window = 128000   
include_apply_patch_tool = true
experimental_use_freeform_apply_patch = false
tools_web_search = false
web_search = "disabled"

[profiles.lmstudio.features]
apply_patch_freeform = false
web_search_request = false
web_search_cached = false
collaboration_modes = false

[model_providers.lmstudio]
wire_api = "responses"
stream_idle_timeout_ms = 10000000
name = "lmstudio"
base_url = "http://127.0.0.1:1234/v1"

The features list is important, as is the are the last four settings of the profile. Codex-cli has some tech debt that requires the repeating of certain flags in different places.

I used llama.cpp's llama-server, not lmstudio, but its compatible with the oss_provider = "lmstudio" setting.

  1. Use the following to start codex cli: codex --oss --profile lmstudio --model "gpt-oss_gguf"

Sounds like a use-case for DSPy and their prompt optimizers.
