The suit — whittled from 26 claims to 2 (breach of charitable trust, unjust enrichment) — will expose private founder communications over four weeks. Meanwhile, the WSJ reported… https://ericchan.io/news-feed/2026-04-28.html https://ericchan.io/news-feed/2026-04-28.html Tue, 28 Apr 2026 12:00:00 GMT Tech Brew lays out an equation that doesn't balance: OpenAI missed its 1B ChatGPT users target for end-of-2025, missed key revenue targets, and CFO Sarah Friar is warning employees that the recent $122B raise could be depleted in three years against Altman's commitment to spend ~$600B on compute by… https://ericchan.io/news-feed/2026-04-27.html https://ericchan.io/news-feed/2026-04-27.html Mon, 27 Apr 2026 12:00:00 GMT OpenAI's April 22 Workspace Agents launch lets any business team describe a recurring workflow in plain English and get a Codex-powered agent that runs across Slack, Drive, Calendar, SharePoint and custom MCP servers — published, scheduled, and embedded inside Slack itself. Nate B Jones argues the… https://ericchan.io/news-feed/2026-04-26.html https://ericchan.io/news-feed/2026-04-26.html Sun, 26 Apr 2026 12:00:00 GMT GitHub Next's Maggie Appleton skewers the dominant "one man, two dozen Claudes" fantasy and argues that as implementation gets cheap, alignment — not coding speed — is the new bottleneck. She demos ACE, a research prototype that puts multiplayer chat, shared microVM cloud computers, and… https://ericchan.io/news-feed/2026-04-25.html https://ericchan.io/news-feed/2026-04-25.html Sat, 25 Apr 2026 12:00:00 GMT Two days after release, GPT-5.5 is sitting at #1 on Terminal-Bench (~12 percentage points ahead of Claude Opus 4.7), Artificial Analysis, LiveBench, and ARC-AGI2 (85%) — at roughly 2x the price of GPT-5.4 Extra High and a 922K-token context. OpenAI's Romain Huet confirmed there will be no separate… https://ericchan.io/news-feed/2026-04-24.html https://ericchan.io/news-feed/2026-04-24.html Fri, 24 Apr 2026 12:00:00 GMT OpenAI's GPT-5.5 hit the top of Artificial Analysis's Intelligence Index a day after launch, but Friday's verdicts from independent reviewers were ruthless. Theo (t3.gg) called it "lazy," "card-slop"-prone, and price-gouging at $5/$30 per 1M tokens (~20% over Opus 4.7). AICodeKing's KingBench 2.0… https://ericchan.io/news-feed/2026-04-23.html https://ericchan.io/news-feed/2026-04-23.html Thu, 23 Apr 2026 12:00:00 GMT OpenAI shipped GPT-5.5 on April 23, leading with the Codex product rather than ChatGPT, and Artificial Analysis immediately scored it the new #1 on the Intelligence Index by 3 points — first place on five of eight headline evals. Pricing doubled to $5/$30 per 1M input/output tokens (with a Pro tier… https://ericchan.io/news-feed/2026-04-22.html https://ericchan.io/news-feed/2026-04-22.html Wed, 22 Apr 2026 12:00:00 GMT Anthropic briefly removed Claude Code from the $20/mo Pro plan, restricting it to the $100–$200 Max tiers, then rolled back after backlash — though Anthropic's Amol Avasare confirmed an A/B test hitting ~2% of new prosumer signups. Same day, GitHub paused new Copilot Individual signups, tightened… https://ericchan.io/news-feed/2026-04-21.html https://ericchan.io/news-feed/2026-04-21.html Tue, 21 Apr 2026 12:00:00 GMT Moonshot's Kimi K2.6 is now the #1 open-weights model — a 1T-total / 32B-active MoE with a 256k window that ranks #4 overall on the AA Intelligence Index at 54, just behind the three closed frontier labs at 57. Agentic Elo jumped from K2.5's 1309 to 1520, τ²-Bench Telecom hit 96%, and the… https://ericchan.io/news-feed/2026-04-20.html https://ericchan.io/news-feed/2026-04-20.html Mon, 20 Apr 2026 12:00:00 GMT Theo walked back a year of pushback and conceded the Opus regression is real, pointing to a BridgeMind benchmark where Opus dropped from 87.6% to 73.3% between launch and April 12. On the same day Simon Willison's updated token-counter measured the Opus 4.7 tokenizer at 1.46× more tokens on text… https://ericchan.io/news-feed/2026-04-19.html https://ericchan.io/news-feed/2026-04-19.html Sun, 19 Apr 2026 12:00:00 GMT Simon Willison rounds up an emerging consensus — articulated by Matt Webb, Marc Benioff, and Brandur Leach — that "headless" software (API-first, no GUI) is becoming the preferred architecture for AI agents acting on behalf of users. Nate B Jones sharpens the same idea into an "agent fork" thesis… https://ericchan.io/news-feed/2026-04-18.html https://ericchan.io/news-feed/2026-04-18.html Sat, 18 Apr 2026 12:00:00 GMT Simon Willison pulled a double shift on Anthropic's published system prompts. First, he diffed the prompt between Opus 4.6 and 4.7 — the "developer platform" got rebranded as "Claude Platform," a PowerPoint slides agent joined Chrome and Excel, and several child-safety and verbosity instructions… https://ericchan.io/news-feed/2026-04-17.html https://ericchan.io/news-feed/2026-04-17.html Fri, 17 Apr 2026 12:00:00 GMT Claude Opus 4.7 ties GPT-5.4 and Gemini 3.1 Pro at the top of Artificial Analysis's Intelligence Index (57.0), runs away with agentic work on GDPval-AA (1,753 Elo, 79 points clear of the field), cuts hallucinations from 61% to 36%, and costs 11% less to eval than 4.6. Theo spent a full day with it… https://ericchan.io/news-feed/2026-04-16.html https://ericchan.io/news-feed/2026-04-16.html Thu, 16 Apr 2026 12:00:00 GMT Anthropic released claude-opus-4-7 at the same $5/M input, $25/M output pricing as 4.6, but with a new tokenizer that encodes the same prompt into up to 1.35x more tokens . Vision leaps: it accepts images up to 2,576px on the long edge (~3.75 megapixels, 3x prior Claude), scores 98.5% on XBOW… https://ericchan.io/news-feed/2026-04-15_2026-04-16.html https://ericchan.io/news-feed/2026-04-15_2026-04-16.html Thu, 16 Apr 2026 12:00:00 GMT Anthropic released Claude Opus 4.7 on April 16 at the same price as 4.6 ($5/$25 per M tokens), posting a 13% jump on code resolution, 21% fewer errors on OfficeQA Pro, and 98.5% on XBOW's visual-acuity benchmark (up from 54.5%). Vision input resolution is tripled to ~3.75 megapixels and a new xhigh… https://ericchan.io/news-feed/2026-04-14.html https://ericchan.io/news-feed/2026-04-14.html Tue, 14 Apr 2026 12:00:00 GMT One week after Anthropic opened Mythos to ~40 orgs via Project Glasswing, OpenAI fired back with GPT-5.4-Cyber and a scaled-up Trusted Access for Cyber program pitched to “thousands of verified individual defenders.” Simon Willison reads the “democratize access” framing skeptically — the real flow… https://ericchan.io/news-feed/2026-04-13.html https://ericchan.io/news-feed/2026-04-13.html Mon, 13 Apr 2026 12:00:00 GMT Nate B Jones argues AI-generated "dark code" — production code that no human ever understood — is not a security or tooling problem but an organizational capability problem, and it will 10x again next year. The same day, Simon Willison quotes Bryan Cantrill making a structurally identical argument… https://ericchan.io/news-feed/2026-04-12.html https://ericchan.io/news-feed/2026-04-12.html Sun, 12 Apr 2026 12:00:00 GMT Tucked into a Google/Broadcom partnership announcement: Anthropic has reached $30B in annualized revenue, a 3x jump since year-end and up 58% since February — enough to flip OpenAI on ARR for the first time. Meanwhile Meta engineers are running an internal leaderboard called "Claudonomics" to see… https://ericchan.io/news-feed/2026-04-11.html https://ericchan.io/news-feed/2026-04-11.html Sat, 11 Apr 2026 12:00:00 GMT Morning Brew's April 11 lead is squarely Wall Street anxiety about Anthropic's newest model and its implications for banking employment — the same labor-replacement narrative that's been building all quarter, now landing on the front page of a general-business newsletter. Morning Brew blocks… https://ericchan.io/news-feed/2026-04-10.html https://ericchan.io/news-feed/2026-04-10.html Fri, 10 Apr 2026 12:00:00 GMT Theo builds a 40-minute case, leaning heavily on Thomas Ptacek's new essay, that frontier models have quietly destroyed the economics of exploit development. The load-bearing quote: we've been safe not because software is secure, but because there weren't enough elite hackers — and now attention is… https://ericchan.io/news-feed/2026-04-09.html https://ericchan.io/news-feed/2026-04-09.html Thu, 09 Apr 2026 12:00:00 GMT Anthropic announced Claude Mythos — a model it says is too dangerous to release generally — and launched Project Glasswing, giving exclusive access to Apple, Google, Microsoft, Cisco, and Broadcom for defensive cybersecurity work. Mythos reportedly found a 27-year-old OpenBSD bug, converted Firefox… https://ericchan.io/news-feed/2026-04-08.html https://ericchan.io/news-feed/2026-04-08.html Wed, 08 Apr 2026 12:00:00 GMT Anthropic announced Claude Mythos Preview — a frontier model so capable at code (and, as an emergent byproduct, at finding software vulnerabilities) that they are explicitly not making it generally available. 78% on SWE-Bench Pro (up from Opus 4.6’s 53), 82% on Terminal Bench, and a 72.4% success… https://ericchan.io/news-feed/2026-04-07.html https://ericchan.io/news-feed/2026-04-07.html Tue, 07 Apr 2026 12:00:00 GMT Ryan Lopopolo, who leads frontier product exploration inside OpenAI Frontier, spent five months running a three-person team that shipped a 1M-line Electron app entirely via Codex — with a self-imposed rule that no human was allowed to write code. By January they hit 5–10 PRs per engineer per day… https://ericchan.io/news-feed/2026-04-06.html https://ericchan.io/news-feed/2026-04-06.html Mon, 06 Apr 2026 12:00:00 GMT Tech Brew surfaces a New Yorker investigation built on internal memos from Ilya Sutskever and Dario Amodei detailing how OpenAI systematically dismantled its safety commitments during the for-profit transition. The promised superalignment team got 1–2% of compute instead of the pledged 20% before… https://ericchan.io/news-feed/2026-04-05.html https://ericchan.io/news-feed/2026-04-05.html Sun, 05 Apr 2026 12:00:00 GMT Google released Gemma 4, a four-size open-weights family (E2B, E4B, 24B MoE, 31B dense) under Apache 2.0, built from the same research as Gemini 3 but shrunk to run on phones, Raspberry Pis, and edge devices. It's natively multimodal (text, image, audio), ships with 128K context on the small models… https://ericchan.io/news-feed/2026-04-04.html https://ericchan.io/news-feed/2026-04-04.html Sat, 04 Apr 2026 12:00:00 GMT Theo delivers a 40-minute polemic arguing that AI has broken the implicit contract of closed-source software: when you make every dev 100x faster, they can ship slop 100x faster too. Cursor Glass "collapsed under the weight of even the most basic changes," the Codex app ships updates that are a… https://ericchan.io/news-feed/2026-04-03.html https://ericchan.io/news-feed/2026-04-03.html Fri, 03 Apr 2026 12:00:00 GMT Swyx and Alessio get Marc Andreessen and Jason Gson at A16Z for a wide-ranging interview in the original A16Z office, days before they move across the road. Andreessen's central claim: Pi + OpenClaw is "one of the 10 most important software" breakthroughs ever, because it marries the LLM to the… https://ericchan.io/news-feed/2026-04-02.html https://ericchan.io/news-feed/2026-04-02.html Thu, 02 Apr 2026 12:00:00 GMT Google shipped four Gemma 4 models — a 31B dense, a 26B/3.8B-active MoE, and two edge models (E2B, E4B) — under an actual Apache 2.0 license, no custom clauses. The architecture is ported down from Gemini 3 research: native vision + audio, built-in thinking/reasoning, function calling, and context… https://ericchan.io/news-feed/2026-04-01.html https://ericchan.io/news-feed/2026-04-01.html Wed, 01 Apr 2026 12:00:00 GMT At 4 AM on March 31, Anthropic's claude-code npm package v2.1.88 shipped with a 57 MB source map file — over 500,000 lines of readable TypeScript that stayed mirrored across GitHub for hours before DMCA takedowns landed. Two fork projects — Python rewrite “Claw Code” and model-agnostic “OpenClaw” …
