Changelog

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

July 26, 2026

  • ImprovedPaper pages now live at readable addresses named after the paper - /papers/attention-is-all-you-need instead of /papers/pwc-19007 - across all 61,000 papers. Old links keep working via redirect.
  • ImprovedSearch-result titles now say what a page actually offers: benchmark pages read "GPQA Diamond benchmark: model scores & leaderboard" instead of just the benchmark's name, leaderboard pages name the current top models in the preview text, and a person's page leads with who they are ("Bob McGrew - Former Chief Research Officer of OpenAI") rather than a generic "researcher" label.

July 25, 2026

  • FixedA model no longer shows up once per reasoning-effort setting. Artificial Analysis benchmarks each setting separately, so Claude Opus 5's launch filled the feed with five near-identical cards - low, medium, high, xhigh and max - and the same duplication ran through the models list, search and compare. Each family is now a single entry, and new launches stay that way. 26 duplicate entries were folded back into 11 models, including Claude Opus 5, Claude Sonnet 5, and GPT-5.6 Sol, Terra and Luna, which each carried six.
  • AddedModel pages now show how the model scores at each reasoning effort, on 90 models. Claude Opus 5 ranges from 60.7 at max effort down to 50.6 at low, on identical pricing; GPT-5.6 Luna spans 51.2 to 26.6. Previously you could only see that by comparing what looked like separate models.

July 24, 2026

  • AddedFirst-time visitors now get a short three-step intro: what the catalog covers, how to search all of it with ⌘K, and how to save a set of feed filters as a view and have new matches emailed to you. Each step shows the actual screen it describes. It replaces the "Start here" band that used to sit on the home page.

July 21, 2026

  • FixedBenchmark scores on model pages now come from the model's strongest setting. Vendors ship many models at several reasoning efforts (GPT-5 at high, medium, low and minimal; GLM-5 with reasoning on or off), and every setting's scores were overwriting the others, so a page could show the weakest setting's numbers under the model's plain name - and which setting won could change from one night to the next. 81 models were affected. GPT-5's GPQA Diamond reads 85.4% instead of 80.8%, and its HLE 26.5% instead of 18.4%.
  • FixedSearch no longer returns dead results. About 500 entries still pointed at models, tools, leaderboards, organizations, and evals that had been merged into another entry or removed, so they either led nowhere or pushed a real result off the list. Search now drops such entries as soon as the entry they point to goes away.
  • FixedThe nightly refresh finishes again. It had been running over its time limit and getting cancelled partway on 4 of the last 10 nights, so fresh benchmark scores, release dates, and newly added papers and people could show up a day or more late, or wait for the next night that happened to finish. The slowest steps are now minutes faster, and the parts that record scores and update search no longer get dropped when an earlier step runs long.

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.
