Anthropic's unreleased Mythos model — capable of autonomously discovering zero-day vulnerabilities and scoring 93.9% on SWE-bench — is restricted to a consortium of AWS, Apple, Google, and Microsoft via Project Glasswing. Vercel open-sourced Open Agents, a reference platform for cloud-based coding agents. Additional updates include Cursor 3 agent splitting, GitHub Copilot data residency and merge conflict fixes, a Microsoft MEMENTO research finding on KV cache persistence, Cloudflare Sandboxes GA, and a Stanford study showing frontier models score 70–80% on vision benchmarks even without images. 65 5 2. 2 [](https://daily.dev/posts/microsoft-and-openai-rewrite-their-deal-anthropic-quietly-paywalls-opus-in-claude-code-9mbsjt0h6 "Microsoft and OpenAI rewrite their deal, Anthropic quietly paywalls Opus in Claude Code") Article Agentic Digest·19w Microsoft and OpenAI rewrite their deal, Anthropic quietly paywalls Opus in Claude Code A packed week in AI developer tooling: Microsoft and OpenAI restructured their partnership, ending exclusivity and letting OpenAI serve customers on any cloud through 2032\. Anthropic began charging Claude Code Pro users extra to access Opus, citing heavy compute consumption under agentic workloads. GitHub is switching Copilot to token-based billing on June 1, removing flat-fee premium requests. China's NDRC blocked Meta's $2B acquisition of Manus, setting a regulatory precedent for Chinese-founded AI startups. Notable items include Kimi K2.6's 1T-parameter open-weight model, OpenAI models coming to AWS Bedrock, a 73-extension supply chain attack on VS Code and forks, DORA data showing AI-heavy teams shipping 19% slower, and xAI's Grok Build expected next week as a Claude Code competitor. 22 1 3. 3 [](https://daily.dev/posts/meta-cuts-8-000-jobs-to-fund-ai-infrastructure-opus-4-7-ships-with-a-hidden-token-cost-csqkg8gvl "Meta cuts 8,000 jobs to fund AI infrastructure, Opus 4.7 ships with a hidden token cost") Article Agentic Digest·20w Meta cuts 8,000 jobs to fund AI infrastructure, Opus 4.7 ships with a hidden token cost A developer-focused news roundup covering: Meta's 8,000-person layoff to fund $115–135B AI infrastructure (not financial distress); Claude Opus 4.7's hidden token cost increase (1.46x text, up to 3x images vs 4.6 at same per-token price); Google DeepMind's Aletheia solving 6/10 novel research math problems zero-shot; and a Vercel security breach involving prompt injection and GitHub Actions cache poisoning that put API keys on sale for $2M. Also covers Grok 4.3 beta, MCP hitting 110M monthly downloads, GitHub Copilot running locally via Ollama, Claude Design launch, and growing security debt in AI-generated code. 13 4 4. 4 [](https://daily.dev/posts/kimi-k2-6-lands-as-a-real-open-source-coding-agent-github-copilot-closes-signups-jpnki1hlv "Kimi K2.6 lands as a real open-source coding agent, GitHub Copilot closes signups") Article Agentic Digest·20w Kimi K2.6 lands as a real open-source coding agent, GitHub Copilot closes signups Kimi K2.6, a 1T-parameter MoE open-source model from Moonshot AI, launched with strong benchmark scores (80.2% SWE-Bench Verified) and ships in Fireworks, OpenCode, and HuggingChat. GitHub Copilot paused new signups for Pro, Pro+, and Student plans as agentic workflows blew past flat-rate cost assumptions, with Opus models being tiered up. Anthropic silently cut Claude Code's prompt cache TTL from 1 hour to 5 minutes in April, causing significant cost spikes for developers in sustained agentic sessions. Claude Desktop was found to silently install a browser bridge granting broad access without user consent. Other notable items include Cursor 3's shift to parallel agent orchestration, a $5B Amazon-Anthropic deal expansion, an MCP STDIO RCE disclosure affecting \~200K servers, and OpenAI losing three senior executives in one day. 11 1 [See all Agentic Digest archives](/sources/agents%5Fdigest/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/agents_digest/best-of/2026/04#page","url":"https://daily.dev/sources/agents_digest/best-of/2026/04","name":"Best Agentic Digest Posts — April 2026","description":"The most upvoted Agentic Digest posts from April 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/agents_digest/best-of/2026/04#items","numberOfItems":4,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/claude-opus-4-6-gets-quietly-nerfed-grok-4-20-tops-bridgebench-x001z8oaf","name":"Claude Opus 4.6 gets quietly nerfed, Grok 4.20 tops BridgeBench"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/microsoft-and-openai-rewrite-their-deal-anthropic-quietly-paywalls-opus-in-claude-code-9mbsjt0h6","name":"Microsoft and OpenAI rewrite their deal, Anthropic quietly paywalls Opus in Claude Code"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/meta-cuts-8-000-jobs-to-fund-ai-infrastructure-opus-4-7-ships-with-a-hidden-token-cost-csqkg8gvl","name":"Meta cuts 8,000 jobs to fund AI infrastructure, Opus 4.7 ships with a hidden token cost"},{"@type":"ListItem","position":4,"url":"https://daily.dev/posts/kimi-k2-6-lands-as-a-real-open-source-coding-agent-github-copilot-closes-signups-jpnki1hlv","name":"Kimi K2.6 lands as a real open-source coding agent, GitHub Copilot closes signups"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"Agentic Digest","item":"https://daily.dev/sources/agents_digest"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/agents_digest/best-of"},{"@type":"ListItem","position":5,"name":"April 2026"}]}]} ```
