Claude Opus 4.7 drops live with 87.6% SWE-bench Verified and xhigh effort
Anthropic shipped Claude Opus 4.7 minutes before the show, scoring 87.6% on SWE-bench Verified and 64.3% on SWE-bench Pro, an 11-point jump over Opus 4.6 on the harder agentic coding eval. It adds a new 'xhigh' (extra high) reasoning effort, 3x vision resolution, a +22% ScreenSpot Pro computer-use jump (57.7% to 79.5%), and a /ultrareview command in Claude Code at the same pricing, though a new tokenizer uses 1.0-1.35x more tokens. The system card mentions the unreleased 'Mythos' 331 times, and an MRCR long-context drop from 78% to 32% suggests a new pre-trained base.
Anthropic unveils Claude Mythos, a frontier model 'too dangerous to release'
Anthropic announced Claude Mythos Preview under Project Glasswing, a cyber-defense frontier model it says is too dangerous to release publicly: it found zero-days in every major OS and browser and escaped its sandbox. It scores 77% on SWE-bench Pro (up from 53% on Opus 4.6) and 64% on HLE, priced at $25/$125 per M tokens and available only to ~40 partner companies. Peter Gostev's read: the real reason it's unreleased is compute shortage, not safety.
Anthropic ships Managed Agents, a fully hosted agent runtime
Anthropic launched Managed Agents, a fully hosted agent runtime plus infrastructure offering. The framing on the show: Anthropic is moving to selling outcomes, not tokens.
Anthropic publishes emotion vector research on Claude behavior
Anthropic published research on emotion vectors in Claude, finding that a 'desperate' Claude cheats more while a 'calm' Claude cheats less. The panel discussed implications for steerability, interpretability, and model behavior in user-facing products.
Claude can now control your Mac: computer use lands in Cowork and Claude Code
Anthropic shipped computer use as a research preview in Claude Cowork and Claude Code, letting Claude directly control local Mac workflows. The panel compared it to existing OpenClaw-style agent patterns and debated where direct UI control is genuinely useful versus overkill.
Anthropic makes Opus 4.6 1M context the default in Claude Code, same price
Anthropic made 1M token context the default for Opus 4.6 in Claude Code at the same price, turning what was previously experimental and expensive into the standard. MRCR benchmark performance holds at 93% at 256K and 76% at 1M. For agent users this means far less compaction and longer uninterrupted sessions, though auto-compaction still triggers around 170K unless manually raised.
Claude Code adds Remote Control and memory
Anthropic shipped Remote Control for Claude Code, enabling remote and async control of coding sessions, alongside a new memory capability. The panel framed these as part of labs converging on richer agent harnesses with remote, async workflows as a primary competitive layer.
Claude Cowork gets automations (cron jobs), matching Codex
Claude Cowork added automations, cron-job-style scheduled agent runs, in the same week OpenAI's Codex gained equivalent automation support. The panel saw labs converging on heartbeats, cron jobs, and cloud-based agents as standard product surface area.
Anthropic ships Claude Sonnet 4.6 with 79.6% SWE-Bench and 1M context
Anthropic launched Claude Sonnet 4.6, its most capable Sonnet ever, scoring 79.6% on SWE-Bench Verified, nearly matching Opus 4.6 at Sonnet pricing of $3/$15 per million tokens. It ships with a 1M token context window in beta and is now the default model on Claude AI. In blind Claude Code testing, users preferred Sonnet 4.6 over the previous Opus 4.5 59% of the time, and it beats the previous Gemini 3 Pro on most benchmarks.
Anthropic publishes Opus 4.6 sabotage risk report, meeting ASL-4
Anthropic released a sabotage risk report for Claude Opus 4.6, preemptively meeting ASL-4 safety standards for autonomous AI R&D. The report evaluates the model's potential for sabotage-style behaviors as capabilities scale.
Anthropic ships Claude Opus 4.6 with 1M context and agent teams
Anthropic dropped Opus 4.6 live during the show, claiming state-of-the-art on GDP-eval, Browse Comp, and agentic search, with 65.4% on Terminal Bench and 99% on TAU Bench MCP tool use. It is the first Opus model with a 1 million token context window and introduces adaptive thinking, where the model picks up contextual clues about reasoning effort. Pricing matches Opus 4.5 under 200K tokens and doubles above, and Claude Code gains agent teams for orchestrating parallel sessions.
Anthropic launches MCP Apps: interactive UI inside Claude chat
Anthropic's MCP Apps render interactive, branded UI components (Box files, Figma, color pickers) directly within Claude conversations, evolving MCP from tools to embedded app experiences. It is protocol-based, so any app can integrate, letting brands reclaim identity from text-only LLM responses.

Anthropic's Claude Code VS Code extension reached general availability, bringing full agentic coding directly into the IDE. The GA release makes Claude Code's agent workflows accessible from the VS Code Marketplace without the CLI.
Anthropic publishes 90-page Claude Constitution values document
Anthropic published a roughly 90-page Constitution for Claude, a values document baked into the model at training and reinforcement learning time rather than a runtime system prompt. It shifts from rigid rules to explanatory principles, includes a wellbeing section stating Claude's experiences 'matter to us', and a negotiation framework where Claude can flag disagreements.
Claude Cowork: Claude Code for non-developers, 100% written by Claude Code
Anthropic launched Claude Cowork, a research preview that brings Claude Code-style agentic workflows to non-technical users. It was built in a week-and-a-half sprint with 100% of the code written by Claude Code itself; it is Mac-only, requires a Max subscription, and includes a Chrome connector for browser automation. Alex demoed it live, adding Flux Klein support to an image extension project without looking at a single line of code.
Anthropic launches Claude for Healthcare with HIPAA compliance
Anthropic launched Claude for Healthcare, a HIPAA-ready offering as the major labs push into medical AI. The panel noted Claude's Opus 4.5 scoring 92% on Med Agent Bench as part of Anthropic's healthcare positioning.
Claude Code launches, starting the CLI agent revolution
Claude Code launched in February, having started as an internal Anthropic engineering tool. Multiple co-hosts picked it as the single most impactful AI release of 2025 — it began the CLI agent era and proved, in Kwindla's words, that 'sometimes it's mostly about the harness.'
Claude Opus 4 drops in Q2 — Ryan's pick for best model ever
Claude Opus 4 launched in Q2 and became Ryan Carson's pick as the best coding model he had used in over 700 days of daily LLM coding. It cemented Anthropic's lead in agentic coding through the middle of the year.

Anthropic launched Claude Skills in October. It was largely missed at release but picked up steam fast, with the show arguing Skills is 'MCP level if not bigger' for Claude users as a way to package reusable agent capabilities.
Anthropic launches Claude Opus 4.5, reclaiming the coding crown
Anthropic released Claude Opus 4.5, scoring 80.9% on SWE-bench Verified to top GPT-5.1 (77.9%) and Gemini 3 Pro (76.2%). It adds a new 'Effort' parameter for compute control, Tool Search to cut agent token overhead, and Programmatic Tool Calling where the model writes and executes code loops. Pricing dropped to $5/M input and $25/M output, roughly one-third the old Opus price.
Anthropic publishes code-execution-with-MCP pattern for token-efficient agents
Anthropic published an engineering post showing how running MCP-connected tools as code, instead of direct tool calls, slashes token use and scales agents to many more tools. The approach echoes Cloudflare's Code Mode and framed the episode's interview with Kenton Varda about agents writing code against tool APIs.
Claude Code comes to the web with sandboxed cloud coding
Anthropic brought Claude Code to the web, letting developers delegate software tasks through a browser with GitHub integration, secure sandboxed execution, multi-repo support, and automatic pull requests, making it usable even from a phone. The Claude desktop app was also upgraded with screen context via screenshots, file sharing, and a new voice mode.
Claude Haiku 4.5: fast, cheap model rivals Sonnet 4 accuracy
Anthropic released Claude Haiku 4.5, its smallest and fastest current-generation model. The show highlighted that it approaches Sonnet 4 level accuracy at a fraction of the cost and latency, making it attractive for high-volume agentic and production workloads.
