Claude Code not working in VS Code with command 'claude-vscode.editor.openLast' not found? The extension failed to start: update it and fully restart VS Code.
Codex projects missing after an update or account switch are usually still on disk. Update to 26.1106.51428, fully quit, and back up .codex before re-adding.

workspace routing discovery failed or timed out clears in most reports with a background-server restart; unauthorized (401) needs a new sign-in on that host.

Gemini 4 Argon and Claude Fable 5.1 tie on Artificial Analysis, yet Fable cost 8.6x Argon on everyday tasks in an October–November test, 4.3x from December 1.
Gemini 4 Argon's default passed 8 small tasks for $0.096 vs $0.41+ on the others. For hard or long exact work, start with Claude Fable 5.2 at medium.
Same tasks, one gateway: Opus 5.5 at high effort cost $0.31, Argon at high $0.40 through Nov 30 and $0.81 from Dec 1, when its token price equals Opus.
Gemini 4 Argon lists at 2.67x 3.8 Flash per token, but on five same-prompt calls it cost 1.57x as much through Nov 30, 2026, and 3.15x in December.
GPT-6 Astra outscores Gemini 4 Argon 55 to 50 at the same high setting. Argon is cheaper at its default, but its API price doubles on December 1, 2026.
Gemini 4 Carbon (gemini-4-carbon) went GA on November 10, 2026 for paid Gemini API keys and is rolling out to Google AI Ultra. $2/$10 per 1M tokens to Nov 30.
Gemini 4 Carbon edges Claude Opus 5.5 on AA's index, 60 to 59, but Opus still leads coding agents and office work, and Carbon's half price ends November 30.
Since November 10, 2026, both cost the same per token, but on identical prompts Carbon wrote 3.8x Argon's output. It pays on hard, long jobs, not quick ones.
Gemini API keys are free, but free inference requires an eligible project, model and feature. Check live limits, grounding exceptions, 403s and data-use rules.
A Gemini API key is free, but usage is free only within per-project limits. Gemini 3.8 Flash costs $0.75/$3.75 per 1M tokens; Gemini 4 Argon is paid-only at $2/$10 until Dec 1.
Gemini API rate limits (RPM, TPM, RPD) apply per project, not per key, and your live numbers are in AI Studio. Tier 2 and Tier 3 unlock at $100 and $1,000 paid.
The Gemini API key from Google AI Studio is free. Flash, Flash-Lite and 2.5 Pro calls are free within project limits; image models and 3.1 Pro need billing.
As of October 10, 2026, paid Gemini API usage runs on Prepay credits. Postpay accounts must switch by their notice date; a $0 balance returns HTTP 402.
The error doesn't prove your plan is excluded: on one Pro account, Codex CLI 0.158.0 got it and 0.159.0 worked. Check the ID, client, daemon, then the account.
Both list at $2/$10 per 1M tokens through November 30, 2026, then Argon doubles. K3.1 Pro leads terminal coding; Argon leads overall and on factual recall.
As of November 2, 2026, Flow caps Nano Banana 2.1 and 2 Lite at 400 images a day, 1,000 on a plan; the Gemini app has 5-hour and weekly limits, no image count.
Nano Banana Pro is $0.134 per 1K/2K image and $0.24 at 4K on Google's API; Google AI Pro is $19.99 a month with no API. LaoZhang API: $0.09 a call at any size.
No single Nano Banana Pro daily limit: Flow caps Pro at 20–500 images a day by plan, the Gemini app refreshes every 5 hours, AI Mode and Workspace reset daily.
