## ModelFusion

ModelFusion is a toolkit aimed at people who work with many large language models at once and want to make better cost and capability decisions. Its core is a set of free, browser-based utilities: an LLM cost calculator that estimates API spend across providers, a prompt tokenizer for counting tokens and trimming prompt length, a model selector quiz, a benchmark comparator using metrics like MMLU and HumanEval, a local LLM runner guide for Ollama and LM Studio, an open-source model directory and a glossary of AI terms.

Beyond the calculators, ModelFusion also markets a product layer: MultiChat for comparing responses from multiple models side by side, document projects for chatting with uploaded PDFs and Word files, a unified API that presents one interface across providers, and usage analytics for tracking cost and performance. The site positions these as suitable for research, business, development and education audiences.

Much of the toolkit is completely free and needs no registration, with the latest model pricing and benchmark data refreshed regularly. Because the underlying costs it reports come from third-party providers, users should still confirm current rates with OpenAI, Anthropic, Google or whichever vendor they rely on, as provider pricing changes often.

**Pricing & Plans:** ModelFusion's calculators, prompt library and comparison tools are advertised as 100% free with no registration required. The platform also lists paid tiers (a Free Trial and Paid options) for its API and enterprise-style usage, so teams needing the unified API or dedicated support should check current plans on the site.

- **LLM cost calculator:** Estimate API costs for GPT-4, Claude, Gemini and 25+ models and compare pricing across providers before you spend.
- **Prompt library and tokenizer:** Access a large library of ready-made prompts and count tokens for any model to reduce cost and improve efficiency.
- **Model selector and benchmark comparator:** Find the best model for a use case and compare MMLU, HumanEval and other performance metrics interactively.
- **MultiChat and document projects:** Chat with several AI models at once for side-by-side comparison, and upload PDFs or Word files to query them with AI.
- **Unified API and observability:** Use a single consistent interface across providers, with analytics for tracking usage, cost and performance.

**Strengths:** Large collection of genuinely free utilities with no sign-up needed.; Useful for comparing pricing and benchmarks across many models in one place.; Covers practical extras like token counting and local model setup guides.; Includes a MultiChat view for comparing model answers directly.

**Limitations:** Some tools are informational and model data can lag behind very fast-moving provider updates.; Cost figures are estimates based on third-party pricing and should be verified with each provider.

## Museum of Models (Rival)

Museum of Models — the project formerly known as Rival — is a free, ad-free archive of how AI models actually answer. Since May 2024, the same 100 questions have been put to every model in the exact same way, once, and every answer has been kept exactly as it was given, including the odd ones and the empty ones. The result is 18,773 answers from 385 models, a record of how each one drew a pelican, built a landing page, told five jokes, or named a favourite city.

The premise is that leaderboards only remember scores. When a lab retires a model and switches it off, its weights often disappear and nobody can ask it anything again. The museum keeps the outputs themselves: 121 of the 385 models featured are no longer served on OpenRouter, yet their drawings, websites, writing and image answers are still here to browse.

Nothing on the site is ranked or scored, and supporting it changes nothing about what it shows. Answers are presented in their native form — drawings as SVG, websites running live in a sandbox, images as pictures, writing as readable pages and voices you can play. Visitors can spin an interactive globe of answers, compare two to four models side by side, sort by release date, lab or question, and step back through a monthly timeline of the museum since it opened. The full collection is downloadable and reusable under CC BY 4.0 with credit.

**Pricing & Plans:** The museum is completely free with no ads. Hosting costs are covered by voluntary donations, such as buying the creator a coffee, and all answer data can be downloaded and reused under CC BY 4.0 with credit.

- **18,773 answers from 385 models:** One hundred identical questions covering drawings, websites, writing, images, code and audio, each answered by every model and kept as given.
- **Retired models preserved:** 121 of the 385 models are no longer served on OpenRouter, yet their answers remain viewable, preserving outputs that would otherwise be lost.
- **Side-by-side comparison:** Add two to four models with a single click and view their answers to the same questions next to each other.
- **Interactive globe and index:** Explore a magnifiable globe of answers, an index sortable by release date, lab or question, a monthly timeline, and a fast command-K search.
- **Live, runnable exhibits:** Generated websites run live in a sandbox, drawings are the model's own SVG, images are shown at 640px, and voices can be played directly.

**Strengths:** Completely free and ad-free, with no login required; Preserves answers from models that have since been retired and switched off; Methodologically consistent: identical prompts, one attempt, documented settings; Open data downloadable under CC BY 4.0 and explorable through globe, index and side-by-side views
