TL;DR
Hugging Face says it fine-tuned Palette, a 20-billion-parameter open-weight model, to create slide decks using IBM Design Language. The company reports top rankings in two of three PresentBench domains and a faster slide-coding stage, but the available account lacks scores, evaluation details and independent results.
Hugging Face says it fine-tuned Palette, a 20-billion-parameter open-weight model, to produce slide decks using IBM Design Language, as described in the original analysis, with a workflow that separates deck planning from slide coding. The company reports that Palette ranked first in two of three domains it measured on PresentBench, but the supplied account gives no scores, domain names or comparison conditions, limiting what readers can conclude from the result.
Palette handles a presentation in two stages through a single LoRA adapter, according to Hugging Face. A designer role turns a request into a structured JSON brief describing the deck’s content, palette, typography, layouts and design rationale. A coder role then uses each slide’s specification to write JavaScript with pptxgenjs. The brief can be reviewed or edited before code is produced, separating decisions about what a deck should communicate from the work of placing text and visual elements.
Hugging Face says the split lets slide-coding tasks run in parallel and makes that stage about six to seven times faster than doing it sequentially. That figure refers to the project’s reported workflow comparison; the supplied account does not describe its measurement method or provide broader production benchmarks. The team also says coder examples were about five times longer than designer examples and that it oversampled designer examples fivefold during training to give that role more representation.
Because the team says no public dataset contains the plans, design decisions and code behind finished presentations, it synthesized training material using a larger open model. Hugging Face reports generating about 1,000 decks covering roughly 10,000 slides, with varied lengths, genres, layouts and prompts. The examples included explanations of why a design choice was made instead of an alternative. The team says it rendered generated decks, checked for overlaps and text overflow, repaired broken slides and added the revised examples to training. These are project-reported methods, not independent assessments of the resulting decks.
Branded Decks Without a Hosted Service
Presentation generation has two practical challenges beyond drafting slide text: keeping output consistent with an organization’s design system and deciding where sensitive material is processed. Hugging Face presents Palette as an approach to both. An open-weight model could, depending on its license and deployment setup, give organizations more control over customization and allow them to run a system on their own infrastructure rather than sending every request to an external service.
Those are potential benefits, not demonstrated deployment outcomes in the supplied account. It does not establish that Palette protects confidential information, show a production deployment, or measure how much editing people still need to do. The reported benchmark ranking suggests performance on some measured deck-building tasks, but without scores and evaluation details it does not show that Palette is broadly better than other systems or suitable for every organization.
The design of the workflow is also relevant beyond this model. Planning a deck before generating its slide code creates an intermediate brief that a person or another system can inspect. That may make design decisions easier to review than a process that produces finished slides without exposing its structure. Whether that translates into more reliable presentations remains a question for testing across varied tasks.

From Slide Brief to Rendered Deck
Slide generation combines editorial judgment with geometric constraints. A system must decide what information belongs on each slide, then turn that plan into readable text and arranged shapes. Hugging Face says smaller models can make layout errors when they generate code without checking the rendered slide: text may overflow, objects may overlap, or a title may be difficult to read. Palette’s brief-first approach is intended to make the content and design decisions explicit before code is written.
The project also describes a limitation in synthesizing its training data: when a specification did not contain enough information, the teacher model could invent content. Hugging Face says examples drawn from reference decks helped steer the teacher’s output more reliably than adding more prompt rules. That account identifies a faithfulness risk in generated presentations, but it does not quantify how often Palette still adds unsupported material or how the issue was evaluated after fine-tuning.
LoRA was used for fine-tuning. Hugging Face says the method made experiments less expensive while adding the deck-building format and skill to the base model. The supplied project account identifies Palette as a 20B model but does not name its base model. It focuses on IBM Design Language; although the account presents training in a user’s design language as a broader possibility, it provides no results for other design systems.
“The designer handles the editorial judgment, and the coder handles the geometry.”
— Hugging Face, describing Palette’s approach
Benchmark and Release Details Missing
The supplied account does not name the three PresentBench domains, provide Palette’s scores, identify the competing systems or describe the evaluation conditions. It is consequently not possible to compare the reported rankings quantitatively or determine how difficult the tested tasks were. The claim that Palette ranked first in two domains remains a result reported by the project’s authors, not an independently verified comparison in the material available here.
Other details are also absent: the base model, the model’s release status and license, and independent testing of generated presentations. The account does not show performance on complex data, strict factual tasks, long decks or design systems other than IBM’s. It also gives no deployment evidence or operational safeguards for handling private inputs. The reported speed improvement lacks a stated measurement method, so its relevance to different workloads is unclear.
Public Weights Could Enable Checks
The supplied account does not announce when model weights, code or detailed evaluation results will be made available. Those materials would let developers and researchers reproduce the workflow and test Palette against other models and presentation tasks. Until then, the benchmark ranking and speed figure should be treated as claims from the project’s authors, with the comparison basis not supplied here.
Further evaluation would need to cover different design languages, longer and more demanding decks, and factual tasks where unsupported content could have consequences. It would also help establish how often the rendering checks catch layout failures and how much correction users must perform. No next release or evaluation date is specified in the source material.
Key Questions
What is Palette?
Palette is a 20-billion-parameter open-weight model that Hugging Face says it fine-tuned to create slide decks using IBM Design Language.
How does Palette generate a presentation?
Its workflow first produces a structured deck brief covering content and design choices, then generates pptxgenjs JavaScript for individual slides. Hugging Face says those roles use a single LoRA adapter.
What did Hugging Face report on PresentBench?
The company says Palette ranked first in two of three measured domains. The supplied account does not give domain names, scores, comparison systems or evaluation conditions, so the result cannot be independently assessed from those details.
Can organizations use Palette for confidential presentations?
The project identifies running an open-weight model on an organization’s own infrastructure as a possible motivation. The supplied account does not report a deployment or establish how Palette handles or protects sensitive information in practice.
Has Hugging Face said when Palette will be released?
No release date, model weights, code or license details are provided in the supplied project account. Their availability remains unclear.
