On May 19, Google announced that Gemini CLI's free access ends June 18. The replacement is Antigravity CLI, a closed-source Go tool with a near-useless 20-request/day free tier. Community reaction to the open-source bait-and-switch has been sharp.
The maker of Devin and Windsurf closed a $1B Series D at a $26 billion post-money valuation, with $492M in annualized revenue and customers including Goldman Sachs, Mercedes-Benz, and NASA.
Anthropic shipped Opus 4.8 forty-one days after Opus 4.7. The headline numbers are a five-point jump on agentic coding, a fast mode that costs a third of what it used to, and a new Claude Code feature that runs hundreds of subagents in parallel for codebase-scale work.
GitHub published two Copilot changelog entries on May 26: Copilot Memory gets better deletion guidance, a repository-level off switch, and CLI commands, while enterprise admins gain targeted model rules that let them pick which models each organization can access.
OpenAI released Codex CLI v0.134.0 on May 26, adding search across local conversation history with case-insensitive matching and result previews. The release also makes read-only MCP tools run concurrently and cleans up profile management.
Anthropic shipped Claude Code v2.1.152 on May 27, adding --fix to the code review command so suggestions land in your working tree automatically. The release also gives skills and slash commands a way to restrict the tool list while they're active.
OpenAI shipped Codex CLI v0.133.0 on May 21, enabling Goals mode by default for all users. The release also adds Vim modal editing to the terminal UI, a new codex doctor diagnostics command, and a reworked permission profiles system.
Modal closed a $355M Series C led by General Catalyst and Redpoint on May 21, crossing $300M ARR after 5x growth in eight months. Its sandbox product — which powers code execution for Devin, Windsurf, and several Claude Managed Agent partners — now accounts for more than a third of revenue.
Anthropic's London developer conference on May 19 launched self-hosted sandboxes in public beta and MCP Tunnels in research preview, letting enterprise teams run Claude agents inside their own infrastructure for the first time.
Zed 1.3.5 ships Terminal Threads as a stable feature, letting developers run Claude Code, Codex, Amp, or any CLI agent as a managed thread in the sidebar. Mermaid diagrams now render inline in the agent panel. Version 1.3.6 follows with Gemini 3.5 Flash and thinking levels for Google models.
Copilot CLI 1.0.52 ships on May 23 with a context window tier fix that actually enforces the 200K vs 1M selection end-to-end, session resume in saved directories, and log file pruning. Version 1.0.53 the next day fixes multiline prompt display and a Bash hang.
Anthropic raised Claude Code weekly limits by 50% for all paid plans on May 13, through July 13. The increase follows a doubling of 5-hour rate limits on May 6 and removal of peak hour throttling — three capacity expansions in five weeks, funded in part by a new compute deal with SpaceX's Colossus 1 data center.
Google shipped Android CLI 1.0 stable at I/O 2026. The command-line interface gives AI agents like Claude Code, Codex, and Antigravity semantic symbol resolution, Compose preview rendering, and UI test execution — with 70% less token usage than running an agent inside Android Studio.
GitHub quietly dropped every Gemini model from Copilot Chat on github.com on May 20, along with GPT-5.2 Codex and GPT-5.4 nano. OpenAI and Claude models remain available. GitHub says it's about reliability — the scope of what was cut says more than the explanation does.
Version 2.1.149 adds a per-category breakdown to /usage — showing exactly how much of your limits comes from skills, subagents, plugins, and each MCP server. It also adds keyboard navigation in /diff and fixes a string of PowerShell permission bypasses.
Version 1.0.51 of the GitHub Copilot CLI adds session resumption with a --session-id flag, an experimental /security-review command for scanning code changes, and extended secret scanning into commit messages and PR descriptions.
Announced at Code with Claude London on May 19, self-hosted sandboxes let enterprises run agent tool execution on their own infrastructure. MCP tunnels let agents reach private servers without opening firewall ports.
A trojanized Nx Console extension was live on the VS Code Marketplace for 11 minutes on May 18. It stole GitHub tokens, AWS keys, npm credentials, 1Password vaults, and Claude Code configuration files from over 6,000 developer machines.
Claude Code 2.1.147 shipped May 21 with pinned background session improvements, auto-updater upgrades, and roughly 30 bug fixes including a wide swath of Windows reliability patches. 2.1.148 followed the next day to fix a bash exit code 127 regression.
Cursor shipped 3.4 on May 13 and 3.5 on May 20, adding full-screen agent tabs, Dockerfile-based cloud development environments, expanded Automations with multi-repo support, and a native Jira integration.
GitHub published the full source code for its Eclipse IDE plugin on May 21, 2026. The repository at github.com/microsoft/copilot-for-eclipse contains roughly 15,000 lines of Java covering code completion, Next Edit Suggestions, chat, and agent mode.
Between May 18-20, GitHub added cheap cloud agent models, brought Gemini 3.5 Flash to IDEs, launched auto model selection in VS Code with a 10% discount, and then stripped all Gemini models from web chat.
Two back-to-back Claude Code releases ship a JSON flag for listing live sessions, improved plugin discovery, better OpenTelemetry tracing, and a rename of /simplify to /code-review with optional effort levels.
GitHub made GPT-5.3-Codex the base model for all Copilot Business and Enterprise organizations on May 17, replacing GPT-4.1. It's GitHub's first long-term support model, guaranteed available through February 2027.
