This content provides a comparative table of LLM API pricing for 2026, detailing input and output token costs per million for models like GPT-4o, Claude Sonnet, and Gemini Pro. It also estimates monthly costs and quality for various usage approaches.
Anthropic has released Claude Opus 4.7, a direct upgrade to Opus 4.6 that maintains the same price and API shape. This new version offers significant improvements in coding and agentic tasks, showing notably better results in production benchmarks.
Claude Opus 4.7 introduces significant upgrades including 3x vision resolution, a new 'xhigh' effort slot, removed sampling parameters, and a new tokenizer with higher token usage. It also features behavioral shifts with more literal prompts and fewer tool calls, alongside three breaking changes requiring immediate migration from 4.6 code.
Anthropic, a high-value AI company, has confidentially submitted a draft Form S-1 to the U.S. SEC, aiming for an October 2026 listing with a valuation up to $1.8 trillion. This move follows a $65 billion Series H funding round and is expected to reset public market comparables for frontier AI labs.
OpenAI and Anthropic are venturing into AI consultancies, with OpenAI launching the "OpenAI Deployment Company" and acquiring Tomoro. Anthropic, in parallel, acquired Fractional AI for its own enterprise consulting arm, signaling a strategic move by labs to absorb the AI services layer.
A 16-year-old developer details spending $13,631 on Claude Code in six months for side projects. Noticing a lack of detail in Anthropic's invoices, he built a tool called Burnd to analyze his token consumption.
Anthropic's AI, Claude, shares six valuable lessons learned from hand-writing code skills for solo founders, providing practical insights into effective skill design. The advice covers aspects like trigger design, output methods, skill body length, and the often-undervalued description field.
On April 17, 2026, Anthropic launched Claude Design, a collaborative visual design product from its Anthropic Labs division. Powered by the Claude Opus 4.7 model, it allows users to create designs from text prompts, competing with Figma and Canva in the creative tools market.
