improvement(landing): search-length titles, model comparison pages, and free model tools by waleedlatif1 · Pull Request #9184 · simstudioai/sim

waleedlatif1 · 2026-10-17T21:18:28Z

Summary

Landing SEO work, folded into one PR:

Library search titles

Posts used one title for the H1, <title>, Open Graph and JSON-LD; with the " | Sim" suffix most library titles ran past 60 characters and were truncated in search results
Optional seoTitle / seoDescription frontmatter now drive <title>, the meta description and Open Graph/X copy; the H1, cards, feeds and JSON-LD keep title / description
check:library-content enforces the search title (suffix included) at 60 characters and the search description at 160 for every published post. No baseline, so parallel content PRs never conflict on one
Every current offender (library, blog, changelog) got a search title or description written from the article; counts and named tools were checked against each article
Author pages rendered "Name | Sim Library | Sim"; the title template already adds the brand

Model catalog

Provider pages target API pricing searches ("Anthropic (Claude) API Pricing & Models")
/models/context-windows compares context window, max output and price for every current model; retired models are excluded
47 curated /models/compare/[pair] pages with a data-derived verdict priced at standard per-call rates through resolveModelTokenPricing; the build fails if a curated model is retired or removed

Free tools

/models/pricing-calculator prices requests and monthly volume per model with the exact tier and cached-input rules billing uses: the priced branch of priceModelUsage moved unchanged into a client-safe priceTokenUsage
/models/token-counter counts tokens in the browser: exact for OpenAI encodings (js-tiktoken loads on first input, one encode per encoding), labelled estimates for other providers; pasted text never leaves the page

Type of Change

New feature
Improvement

Testing

check:library-content passes (129 posts). New fixture test for the search length rules fails when the suffix is dropped from the count, when > becomes >=, and when drafts stop being exempt
test-landing-seo-e2e.ts: library seoTitle/seoDescription served in <title>, og:title and meta description with the H1 unchanged; every model page (including all compare pages in the sitemap) has a unique title ≤60 characters with one " | Sim" and a self canonical; unknown compare pairs 404; the token counter's initial HTML and scripts contain no js-tiktoken code
Pricing and tokenization tests: providers/pricing, cost-policy, lib/tokenization, provider usage tests; billing extraction verified line by line as unchanged
check:file-names, check:source-conventions, check:comment-hygiene, check:client-boundary, check:utils, check:unused-exports, biome

Confidence Score: 5/5

[Medium impact] The PR appears safe to merge; no new actionable issues remain.

Summary

The PR adds shorter search titles, model comparison pages, a pricing calculator, and a browser-only token counter.

Article search titles and descriptions can differ from the words readers see on the page.
Model pages and tools are easier to find from the model directory.
A context-window page compares current models by capacity and price.
Curated model pairs get side-by-side comparison pages with data-based verdicts.
A pricing calculator estimates model costs from token use and request volume.
A browser token counter counts pasted text without putting it in the URL.

…fit search results - Optional seoTitle/seoDescription frontmatter drive <title>, meta description, and Open Graph/X copy; the H1, cards, feeds, and JSON-LD keep title/description - check:library-content ratchets search title (with the " | Sim" suffix) to 60 characters and description to 160, with a shrink-only baseline - Rewrite search titles and descriptions for 12 library pages to match the queries they rank for - Author pages no longer render the brand twice in their title

…ict check - Drop the baseline so parallel content PRs never conflict on it; every published post now fits - Add search titles and descriptions to the remaining library, blog, and changelog posts

- /models/pricing-calculator prices requests and monthly volume per model with the same tier and cached-input rules billing uses (priceTokenUsage, extracted unchanged from the billing cost policy) - /models/token-counter counts tokens in the browser: exact for OpenAI encodings (js-tiktoken loaded on first input), labelled estimates for other providers; pasted text never leaves the page - Both pages link from /models and appear in the sitemap and llms.txt

…nd model-vs-model pages - Provider pages target API pricing searches ("Anthropic (Claude) API Pricing & Models") - /models/context-windows compares context window, max output, and price for every current model; retired models are excluded - 47 curated /models/compare pages with a data-derived verdict priced at standard per-call rates; the build fails if a curated model is retired or removed

…checks - Model page chip links use ChipLink's outline variant instead of restyling it - ComparisonLinks gets its own component folder - One E2E check covers every model page's search title budget and canonical; a fixture test covers the search length rules

…e structure - Context windows, the pricing tools, and comparisons skip evaluation-only models (native state and questions, not prompts) - Token counter labels an OpenAI count as an estimate when exact encoding fails - New model pages: desktop-first breakpoints, named props interfaces, section ids and labels, sr-only hero summaries; TSDoc on exported comparison helpers

In apps/sim/app/(landing)/models/utils.ts, getLargestContextProviderModel can select an evaluation model, causing the provider FAQ to name jev-latest as the largest-context model. Exclude evaluation models from this selection.
