Changelog

Notable updates to Sophon - new features, fixes, and improvements, newest first.

June 26, 2026

  • AddedModels that are announced but not generally available - like OpenAI's new GPT-5.6 Sol, Terra, and Luna, or the rolled-back Claude Fable 5 - now carry a "Not available" badge across the catalog, and their score bars render with a checkerboard fill on the charts, the same way Artificial Analysis flags them. Numbers that are still provisional (independent evaluation forthcoming) show a diagonal hatch.

June 10, 2026

  • FixedPasting a Papers link into an AI assistant (or any reader that doesn't run JavaScript, like crawlers) now shows the actual paper list with the link's filters applied - week/month/year window, domain, search. Previously such tools got an empty page shell with no papers at all.

June 9, 2026

  • FixedNew models, scores, and papers land in the feed every night again. The nightly data sync had been timing out and getting cut off partway for a week (Jun 2-8), so several days of updates surfaced late or not at all.
  • AddedClaude Fable 5 and Claude Mythos 5 (released today) are in the catalog with their full launch benchmark table - 13 evals including seven new ones (FrontierCode, ExploitBench, BioMysteryBench, and more), pricing, and specs. Each benchmark shows Fable 5 against Opus 4.8, GPT-5.5, and Gemini 3.1 Pro, with scores marked by who reported them.

June 8, 2026

  • AddedAI models now have a "Mentions on X" tab on their page, showing what people are saying about the model on Twitter/X - filtered for spam, ranked by signal, and tagged by what kind of mention it is (comparison, result, news, opinion). Sort by signal, most recent, or most-liked.
  • FixedAn eval's README tab now shows the actual README again, instead of a block of raw configuration text (title, tasks, tags, and so on).
  • ImprovedA model page now loads its benchmark-score charts in batches as you scroll, instead of rendering all of them at once, so pages for models measured on dozens of benchmarks no longer stall.
  • ImprovedThe Papers "Trending" tab now defaults to the last month instead of all time, so it reflects what's actually trending now; switch to this week or this year anytime.

June 6, 2026

  • AddedSearch results in the API and `sophon` CLI can now be sorted: pass `sort=title` or `sort=recent` (prefix `-` to reverse) to `/api/v1/search`, or `sophon search … --sort title`. The default stays relevance.

June 3, 2026

  • ImprovedOpening a paper's first-page preview now expands it into the reader with a quick animation, and collapses back when you close it, instead of opening abruptly.

June 2, 2026

  • AddedBranded social preview cards for every page - the image shown when a Sophon link is shared on Slack, X, Discord, or LinkedIn. Previously only paper pages had one; the homepage card shows live catalog counts.
  • AddedA public API and a `sophon` command-line tool for querying the catalog (evals, models, tools, papers) from code, agents, or the terminal - find them on the new API & CLI page, linked in the sidebar.
  • FixedCollapsing the sidebar no longer briefly flashes its floating version before it closes.
  • FixedThe feed's New tab no longer shows older papers as if they were just published; papers are ordered by their real publication date again.
  • FixedWhen a paper's preview image fails to load, the feed and paper page now render the paper's real first page instead of a broken image or blank placeholder.
  • FixedPaper abstracts no longer show raw LaTeX code (like `\textsc{}` or `\href{}{}`); the markup is cleaned up so the text and links read normally.
  • ImprovedThe Capabilities page is now grouped into categories (reasoning, language, safety, agents, coding, and more) you can filter by, instead of one long flat list.
  • ImprovedOn list pages, moving between the filter menus now glides the dropdown across to the next filter (or the Add filter button) in place, instead of closing one and opening the next.
  • ImprovedHovering a benchmark bar on a feed model card now explains what the benchmark measures, instead of repeating its name and score.
  • ImprovedIn a paper's PDF, hovering a highlight you saved now shows its note inline; click it to edit.
  • ImprovedThe OSWorld, DABstep, Arena-Hard, and AlpacaEval leaderboards now refresh automatically every day, instead of only when updated by hand.

June 1, 2026

  • AddedFresh arXiv papers are discovered and added automatically every day.
  • AddedNew benchmarks from AfterQuery (agentic IDE coding, quant trading, web-app generation, finance) and Vals AI (tax, finance, legal, and medical domain evals), with model scores.
  • FixedThe feed could freeze on stale content and stop showing new items; it now updates as soon as new evals, models, tools, or papers land.
  • FixedModel cards no longer show "$0/M" or "0 tok/s" before a model's price and speed have been measured.
  • ImprovedThe feed's paper stream now shows only notable papers.
  • ImprovedPapers in the feed now display their own generated preview cards instead of external thumbnails.

May 30, 2026

  • AddedSubscribe to any feed view by email digest (weekly or monthly) or RSS.
  • AddedRename saved feed views inline.
  • FixedLeaderboard pages no longer scroll sideways on mobile.
  • FixedLeaderboard pages no longer freeze on mobile when a board tracks many charts.
  • FixedPrivate notes no longer zoom the page on iOS or flash a phantom scrollbar.
  • ImprovedModel list shows price, prompt caching, speed, latency, and context as optional inline tags you toggle per field.
  • ImprovedFeed model rows explain each spec (context, price, speed, license) on hover.
  • ImprovedEval pages group similar evals into their own tab.
  • ImprovedLarge leaderboards load faster, revealing more models as you scroll.
  • ImprovedLeaderboards show when their scores were last refreshed, next to how often they update.

May 29, 2026

  • AddedBento landing homepage with per-feature previews.
  • AddedFilterable feed header with saved views.
  • FixedCmd-K search shows the most relevant results first.
  • FixedFeed "New" orders by real release date.
  • FixedHorizontal tab strips no longer scroll vertically.
  • ImprovedModel titles are cleaner and more consistent.
  • ImprovedOrganization pages rank lab models by intelligence and release date.
