The headlines of Llama 4 are glowing: 2 new medium-size MoE open models that score well, and a third 2 Trillion parameter "behemoth" promised that should be the largest open model ever released, restoring Meta's place at the top of the charts:

SOTA training updates are always welcome: we note the adoption of Chameleon-like early fusion with MetaCLIP, interleaved, chunked attention without RoPE (commented on by many), native FP8 training, and trained on up to 40T tokens.

While the closed model labs tend to set the frontier, Llama usually sets the bar for what open models should be. Llama 3 was released almost a year ago, and subsequent updates like Llama 3.2 were just as well received.

Usual license handwringing aside, the tone of Llama 4's reception has been remarkably different.

1. Llama 4 was released on a Saturday, much earlier than seemingly even Meta, which changed the release date last minute from Monday, expected. Zuck's official line is simply that it was "ready".
2. Just the blogpost, nowhere near the level of the Llama 3 paper in transparency
3. The smallest "Scout" model is 109B params, which cannot be run on consumer grade GPUs.
4. The claimed 10m token context is almost certainly far above what the "real" context is when trained with 256k tokens (still impressive! but not 10m!)
5. There was a special "experimental" version used for LMarena, which caused the good score - that is not the version that was released. This discrepancy forced LMarena to respond by releasing the full dataset for evals.
6. It does very poorly on independent benchmarks like Aider
7. Unsubstantiated posts on Chinese social media claim company leadership pushed for training on test to meet Zuck's goals.

The last point has been categorically denied by Meta leadership:

but the whiff that something is wrong with the release has undoubtedly tarnished what would otherwise be a happy day in Open AI land.

AI Reddit Recap

/r/LocalLlama Recap

Theme 1. "Transforming Time Series Forecasting with Neuroplasticity"

• Neural Graffiti - A Neuroplasticity Drop-In Layer For Transformers Models (Score: 170, Comments: 56): The post introduces Neural Graffiti, a neuroplasticity drop-in layer for transformer models. This layer is inserted between the transformer layer and the output projection layer, allowing the model to acquire neuroplasticity traits by changing its outputs over time based on past experiences. Vector embeddings from the transformer layer are mean-pooled and modified with past memories to influence token generation, gradually evolving the model's internal understanding of concepts. A demo is available on GitHub: babycommando/neuralgraffiti. The author finds liquid neural networks "awesome" for emulating the human brain's ability to change connections over time. They express fascination in "hacking" the model despite not fully understanding the transformer's neuron level. They acknowledge challenges such as the cold start problem and emphasize the importance of finding the "sweet spot". They believe this approach could make the model acquire a "personality in behavior" over time.

  • Some users praise the idea, noting it could address issues needed for true personal assistants and likening it to self-learning, potentially allowing the LLM to "talk what it wants".
  • One user raises technical considerations, suggesting that applying the graffiti layer earlier in the architecture might be more effective, as applying it after the attention and feedforward blocks may limit meaningful influence on the output.
  • Another user anticipates an ethics discussion about the potential misuse of such models.

Theme 2. "Disappointment in Meta's Llama 4 Performance"

• So what happened to Llama 4, which trained on 100,000 H100 GPUs? (Score: 256, Comments: 85): The post discusses Meta's Llama 4, which was reportedly trained using 100,000 H100 GPUs. Despite having fewer resources, Deepseek claims to have achieved better performance with models like DeepSeek-V3-0324. Yann LeCun stated that FAIR is working on the next generation of AI architectures beyond auto-regressive LLMs. The poster suggests that Meta's leading edge is diminishing and that smaller open-source models have been surpassed by Qwen, with Qwen3 is coming....

  • One commenter questions the waste of GPUs and electricity on disappointing training results, suggesting that the GPUs could have been used for better purposes.
  • Another commenter points out that the Meta blog post mentioned using 32K GPUs instead of 100K and provides a link for reference.
  • A commenter criticizes Yann LeCun, stating that while he was a great scientist, he has made many mispredictions regarding LLMs and should be more humble.

• Meta's Llama 4 Fell Short (Score: 1791, Comments: 175): Meta's Llama 4 models, Scout and Maverick, have been released but are disappointing. Joelle Pineau, Meta’s AI research lead, has been fired. The models use a mixture-of-experts setup with a small expert size of 17B parameters, which is considered small nowadays. Despite having extensive GPU resources and data, Meta's efforts are not yielding successful models. An image compares four llamas labeled Llama1 to Llama4, with Llama4 appearing less polished. The poster is disappointed with Llama 4 Scout and Maverick, stating that they 'left me really disappointed'. They suggest the underwhelming performance might be due to the tiny expert size in their mixture-of-experts setup, noting that 17B parameters 'feels small these days'. They believe that Meta's struggle shows that 'having all the GPUs and Data in the world doesn't mean much if the ideas aren't fresh'. They praise companies like DeepSeek and OpenAI for showing that real innovation pushes AI forward and criticize the approach of just throwing resources at a problem without fresh ideas. They conclude that AI advancement requires not just brute force but brainpower too.

  • One commenter recalls rumors that Llama 4 was so disappointing compared to DeepSeek that Meta considered not releasing it, suggesting they should have waited to release Llama 5.
  • Another commenter criticizes Meta's management, calling it a 'dumpster fire', and suggests that Zuckerberg needs to refocus, comparing Meta’s situation to Google's admission of being behind and subsequent refocusing.
  • A commenter finds it strange that Meta's model is underwhelming despite having access to an absolutely massive amount of data from Facebook that nobody else has.

• I'd like to see Zuckerberg try to replace mid level engineers with Llama 4 (Score: 381, Comments: 62): The post references Mark Zuckerberg's statement that AI will soon replace mid-level engineers, as reported in a Forbes article linked here. The author is skeptical of Zuckerberg's claim, implying that replacing mid-level engineers with Llama 4 may not be feasible.

  • One commenter jokes that perhaps Zuckerberg replaced engineers with Llama3, leading to Llama4 not turning out well.
  • Another commenter suggests that he might need to use Gemini 2.5 Pro instead.
  • A commenter criticizes Llama4, calling it "a complete joke" and expressing doubt that it can replace even a well-trained high school student.

Theme 3. "Meta's AI Struggles: Controversies and Innovations"

• Llama 4 is open - unless you are in the EU (Score: 602, Comments: 242): Llama 4 has been released by Meta with a license that bans entities domiciled in the European Union from using it. The license explicitly states: "You may not use the Llama Materials if you are... domiciled in a country that is part of the European Union." Additional restrictions include mandatory use of Meta's branding (LLaMA must be in any derivative's name), required attribution ("Built with LLaMA"), no field-of-use freedom, no redistribution freedom, and the model is not OSI-compliant, thus not considered open source. The author argues that this move isn't "open" in any meaningful sense but is corporate-controlled access disguised in community language. They believe Meta is avoiding the EU AI Act's transparency and risk requirements by legally excluding the EU. This sets a dangerous precedent, potentially leading to a fractured, privilege-based AI landscape where access depends on an organization's location. The author suggests that real "open" models like DeepSeek and Mistral deserve more attention and questions whether others will switch models, ignore the license, or hope for change.

  • One commenter speculates that Meta is trying to avoid EU regulations on AI and doesn't mind if EU users break this term; they just don't want to be held to EU laws.
  • Another commenter notes that there's no need to worry because, according to some, Llama 4 performs poorly.
  • A commenter humorously hopes that Meta did not use EU data to train the model, implying a potential double standard.

• Meta’s head of AI research stepping down (before the llama4 flopped) (Score: 166, Comments: 31): Meta's head of AI research, Joelle, is stepping down. Joelle is the head of FAIR (Facebook AI Research), but GenAI is a different organization within Meta. There are discussions about Llama4 possibly not meeting expectations. Some mention that blending in benchmark datasets in post-training may have caused issues, attributing failures to the choice of architecture (MOE). The original poster speculates that Joelle's departure is an early sign of the Llama4 disaster that went unnoticed. Some commenters disagree, stating that people leave all the time and this doesn't indicate problems with Llama4. Others suggest that AI development may be slowing down, facing a plateau. There's confusion over Meta's leadership structure, with some believing Yann LeCun leads the AI organization.

  • One commenter clarifies that Joelle is the head of FAIR and that GenAI is a different org, emphasizing organizational distinctions within Meta.
  • Another mentions they heard from a Meta employee about issues with blending benchmark datasets in post-training and attributes possible failures to the choice of architecture (MOE).
  • A commenter questions Meta's structure, asking if Joelle reports to Yann LeCun, indicating uncertainty about who leads the AI efforts at Meta.

• “Serious issues in Llama 4 training. I Have Submitted My Resignation to GenAI“ (Score: 922, Comments: 218): An original Chinese post alleges serious issues in the training of Llama 4, stating that despite repeated efforts, the model underperforms compared to open-source state-of-the-art benchmarks. The author claims that company leadership suggested blending test sets from various benchmarks during the post-training process to artificially boost performance metrics. The author states they have submitted their resignation and requested their name be excluded from the technical report of Llama 4, mentioning that the VP of AI at Meta also resigned for similar reasons. The author finds this approach unethical and unacceptable. Commenters express skepticism about the validity of these claims and advise others to take the information with a grain of salt. Some suggest that such practices reflect broader issues within the industry, while others note that similar problems can occur in academia.

  • A commenter points out that Meta's head of AI research announced departure on Tue, Apr 1 2025, suggesting it might be an April Fool's joke.
  • Another commenter shares a response from someone at Facebook AI who denies overfitting test sets to boost scores and requests evidence, emphasizing transparency.
  • A user highlights that company leadership suggesting blending test sets into training data amounts to fraud and criticizes the intimidation of employees in this context.

Mixture of Experts, Large Language Models, Gradient-Free Learning Methods, Hyper-connections as alternative to residual connections, Attention Sinks in LLMs

• *MoE++ Framework Achieves Expert Throughput: A new MoE++ framework integrates Feed-Forward Network (FFN) and zero-computation experts (zero expert, copy expert, and constant expert) for enhanced effectiveness and efficiency, achieving 1.1$\sim$2.1$\times$ expert forward throughput compared to vanilla MoE* models, according to this research paper.
  • The design of MoE++ offers advantages such as Low Computing Overhead by enabling dynamic token engagement, unlike uniform mixing in vanilla MoE.
• *NoProp Offers Gradient-Free Learning: A new learning method named NoProp*, which does not rely on either forward or backwards propagation and takes inspiration from diffusion and flow matching methods, learns to denoise a noisy target at each layer independently, described in this paper.
  • There's a GitHub implementation by lucidrains and also a discussion that the pseudocode at the end of the paper says they're effecting the actual updates using gradient based methods.
• *Meta releases Llama 4: Meta announced the Llama 4 family of models, including Llama 4 Scout, a 17 billion parameter model with 16 experts and a 10M token context window, outperforming Gemma 3, Gemini 2.0 Flash-Lite, and Mistral 3.1* in its class, as noted in this blog post.
  • Llama 4 Scout's 10M context is trained on a mix of publicly available, licensed data, and information from Meta’s products and services including posts from Instagram and Facebook and people’s interactions with Meta AI.
• *Hyper-Connections Offer Alternative to Residual Connections: Hyper-connections*, serve as an alternative to residual connections, addressing the seesaw effect between gradient vanishing and representation collapse, as outlined in this paper.
  • The architecture is simple like an unrolled diffusion model and the magic here is more about the independence of each layer wrt each other.
• *Attention Sinks in LLMs Prevent Over-Mixing: A recent paper argues that attention sinks*, where LLMs attend heavily to the first token in the sequence, is a mechanism that enables LLMs to avoid over-mixing, detailed in this paper.
  • An earlier paper (https://arxiv.org/abs/2502.00919) showed that attention sinks utilize outlier features to: catch a sequence of tokens, tag the captured tokens by applying a common perturbation, and then release the tokens back into the residual stream, where the tagged tokens are eventually retrieved.

• Mojo Spec Debate Heats Up: A discussion started around whether Mojo will have a spec, with some arguing that it gives a language responsibility and maturity, referencing the design principles of Carbon.
  • Others countered that Mojo's design is tightly coupled to what MAX needs and that a spec would slow down development, with one member stating that Chris Lattner blames "design by committee" for the failure of OpenCL.
• Mojo's Copy Semantics clarified: A member inquired whether Mojo's implicit copies use Copy-on-Write (CoW).
  • Another member clarified that semantics wise, always copy; optimisation wise, many are turned into move or eliminated entirely (inplace). Though it happens at compile time, CoW is a run time thing.
• ChatGPT's Mojo Skills Under Scrutiny: A member asked if ChatGPT or alternatives are good enough to rewrite a large Python project in Mojo.
  • Another member responded that ChatGPT isn't good at any new languages.

Workflow as a Tool, Multi-Agent System with Supervisor Pattern, RAG System with LlamaParse, Scalability Issue with DocumentSummaryIndex, Tools retry when exception occurred

• Wrap Workflows as Tools with FunctionTool: To transform a Workflow into a Tool, one can use the FunctionTool to wrap the workflow and gain control over its name, description, input annotations, and return values.
  • A member suggested a code snippet:

async def tool_fn(...):
  """Some helpful description"""
  result = await workflow.run(...)
  return str(result)

tool = FunctionTool.from_defaults(tool_fn)

• Agent Handoffs Supersede Supervisor Pattern: When building a multi-agent system, it is more robust to have agents handoff between each other as needed, instead of using a supervisor pattern, which can be more error prone.
  • A GitHub repo was shared as an example of a supervisor pattern implementation.
• Replicate Document Summary Index with Vector Store Index: The DocumentSummaryIndex may have scalability issues; it's advised to replicate its functionality using a normal VectorStoreIndex by summarizing documents, indexing with reference IDs, and swapping summary nodes with the original document during retrieval.
  • When using load_index_from_storage, the index store is loaded to memory which causes latencies as more documents are ingested.
• Context's State Prepending to user_msg: To avoid prepending the state content in the user message, one should avoid using the state key in the context and put data between tools elsewhere in the context.
  • A suggestion was to use ctx.set("some_key", "some_val") and ctx.get("some_key") instead.
• Implement Text-to-SQL Query Engine Tool: When implementing a text-to-SQL query engine tool for an agent, if there are only a few tables, it is not necessary to create an index of table descriptions and perform a vector query.
  • In cases of a small number of tables, the index and vector search parts can be skipped for better performance.

torch-geometric for tinygrad, Llama 4 10M context limitations, fast pattern matcher bounty, UOps generation, tinygrad YouTube video

• Tinygraph: Torch-geometric for Tinygrad?: A member inquired about the feasibility of creating a module similar to torch-geometric for graph ML within tinygrad, considering tinygrad's existing torch interface.
  • They questioned whether it would be "useful" to pursue such a module.
• Llama 4's long context may not be so good: A user shared a tweet claiming Llama 4's declared 10M context is "virtual" because models were not trained on prompts longer than 256k tokens.
  • The tweeter also stated that even problems below 256k tokens may yield low-quality output due to the difficulty of obtaining high-quality training examples and that the largest model with 2T parameters "doesn't beat SOTA reasoning models".
• $2000 Fast Pattern Matcher Bounty is available: A member highlighted an open $2000 bounty for a fast pattern matcher in tinygrad.
  • The proposed solution involves a JIT for the match function, avoiding function calls and dict copies.
• Reduce UOps to Speed Up Rewrite: It was suggested that tinygrad sometimes generates more UOps than needed, increasing the cost to rewrite.
  • A member asked if it would be acceptable to sacrifice a few lines to generate fewer UOps initially, even if they are later optimized to the same result.
• Tinygrad YouTube video shared: A member shared a link to a YouTube video.
  • No additional details were given.

Tensor and SimpleMathTrait inheritance, Mesozoic tinygrad tutorials issues, METAL sync issue, AMD and BEAM issues

• Debate About Tensor Inheriting SimpleMathTrait: A discussion arose regarding whether Tensor should inherit from SimpleMathTrait, given that it re-implements every method that SimpleMathTrait provides without using the .alu() function.
  • It was noted that a previous bounty for refactoring Tensor to inherit from MathTrait was canceled due to poor submissions, with some suggesting Tensor may not need to inherit from either.
• Colab CUDA Bug Causes Mesozoic Tinygrad Tutorial Issues: A user encountered issues while running code from the mesozoic tinygrad tutorials in Colab, prompting others to request the error message for debugging.
  • It was identified as a Colab bug related to incompatible CUDA and driver versions, with a suggested workaround involving specific apt commands to remove and install compatible versions; in the meantime using the CPU device was suggested.
• METAL Sharding Behavior Leads to Unexpected Results: A member encountered unexpected behavior in sharding while trying to reproduce a minimal example of a METAL sync issue, suspecting that the COPY from METAL:1 to CPU might be executing before the XFER from METAL to METAL:1 completes.
  • The DEBUG output seemed to show the timeline adding the XFER when committed to the GPU command queue, not when it ends.
• AMD and BEAM cause AssertionError: A user encountered an AssertionError when running with BEAM=2 and AMD=1, which seemed to be related to opening the device outside of the if __name__ == "__main__" block.
  • Setting PARALLEL=0 or ensuring the device is opened within the if __name__ == "__main__" block resolved the issue.
