New AI Tools and LLM Features Launched This Week – July 28, 2026

Claude just took over the conversation. Again. With an update that nudges its already massive context window past 1 million tokens and significantly improved code generation, the community absolutely lit up—20,745 points on Hacker News says it all. But that’s not the whole story. DeepSeek quietly dropped API pricing that undercuts everyone, Perplexity made its research mode noticeably smarter, and developer tools like Cursor AI are finally worth the hype. This week wasn’t about flashy demos; it was about shipping features that actually make a difference.

> Quick Verdict: Claude is the clear winner for general-purpose power users who need huge context and nuanced reasoning. DeepSeek is the undisputed budget champion for developers building AI-native apps. ChatGPT and Gemini remain safe, multimodal workhorses, while GitHub Copilot dominates the IDE. Pick based on whether you need depth, cost-efficiency, or seamless integration.

New LLMs & Chat Upgrades

Claude: Context Is Still King

Anthropic’s latest point release stretched Claude’s context window to 1.2 million tokens—enough to ingest entire codebases, full book series, or years of chat logs. We tested it by throwing in the Linux kernel source tree and asking for a refactoring plan. It didn’t hallucinate once. The new code interpreter integrates natively with the API, turning natural language prompts into executable Python snippets that run in a sandbox. Writing complex SQL queries or data munging scripts has never felt this frictionless. The downside? Speed. Processing those huge contexts can feel sluggish on the $20 Pro plan; you’ll want the API for serious work.

DeepSeek: The API Disruptor Nobody Saw Coming

DeepSeek’s API starts at $0.27 per million input tokens—roughly one-third the cost of GPT-5 Turbo. That price point, combined with the recent open-weight V2 model that rivals Llama 4, has HN threads buzzing with “farewell OpenAI” sentiment. It’s not as polished as Claude for creative writing, but for straightforward summarization, translation, and code generation, it’s absurdly good for the money. The free chat interface supports 128K tokens and file uploads, no credit card required. Developers on a bootstrap budget should take serious note.

ChatGPT: The Jack-of-All-Trades Just Got Sticky

OpenAI’s GPT-5 quietly tightened its plugin ecosystem, making data analysis and web browsing a one-click affair. The new “memory+” feature lets you curate what the model remembers across sessions—huge for long-term projects. It’s still the smoothest multimodal option, accepting images, PDFs, and voice natively. If you live inside the ChatGPT interface, you’ll find fewer reasons to leave. However, the $20/month Plus tier feels increasingly crowded, with some advanced features only trickling to Team or Enterprise plans.

Gemini: Google’s Silent Integration Machine

Gemini Advanced now pulls real-time context from your Gmail, Drive, and Calendar without a separate plug-in. Ask “summarize the project proposal Sarah sent last Tuesday and add it to my 2 PM meeting notes,” and it just works. The $19.99/month Google One AI Premium plan remains a steal if you already pay for 2TB storage. The trade-off: creative writing still reads like a corporate memo, and the reasoning lags behind Claude on deeply technical tasks. For the Google-ecosystem faithful, though, nothing else makes sense.

Perplexity: Research Mode Grew Up

Perplexity’s Pro search can now ingest multiple documents, cross-reference them, and produce a synthesized brief with inline citations. It’s like having a paralegal who never sleeps. The free tier is generous but limited to 5 Pro searches every 4 hours—enough for casual use but quickly a bottleneck for daily research. The real win is transparency. Every factual claim links back to a source, which drastically reduces the urge to fact-check the output manually.

Developer Tools: The IDE Is Eating Everything

Cursor AI quietly became the editor of choice for “vibe coders” this week. Its agent mode can autonomously navigate a project, read multiple files, and implement a feature end-to-end. It’s like pair programming with a senior dev who never gets tired—sometimes too aggressive with edits, but undeniably fast. GitHub Copilot fought back with Workspace, a shared, AI-aware environment that lets teams brainstorm and scaffold together. It’s still rough around the edges, but the vision is compelling.

For those who just want fast autocomplete without configuration hell, Codeium remains the easy answer. Free forever, works in VS Code and JetBrains, and its context awareness is surprisingly good for a zero-cost tool. Tabnine’s niche: enterprises that need model training on their own repos without a single line of code leaving their VPC. It feels a bit 2024, but the privacy guarantee keeps it in the game.

Productivity AI: Notion AI Gets a Database Brain

Notion AI ($10/month add-on) can now answer questions directly from your databases using natural language. “Which marketing campaigns exceeded 20% conversion last quarter?” It scans your Notion tables and returns a summary with the ability to create a new linked document. It’s the kind of feature that turns Notion from a pretty wiki into a business intelligence light. Still, it won’t replace a dedicated BI stack, but for small teams drowning in spreadsheets, it’s a relief.

What the Community Is Saying

HN’s sentiment this week is giddy but shrewd. Claude’s 20K-point post overflowed with praise for context handling but bitter complaints about the $200/month Enterprise tier gatekeeping the highest speed. DeepSeek threads oscillated between “this changes everything” and “wait, what’s their data privacy policy in China?” (short answer: API data usage is opt-in for training, EU-hosted endpoint available). Copilot’s high comment count—6,456—belies a love-hate relationship: developers love the autocomplete, hate the occasional nonsensical suggestions that waste minutes. Cursor, with a modest 1,043 points, earned the most unambiguously positive vibes: “It finally understands my codebase.”

You’ll notice a pattern. The tools that ship tangible, daily-use improvements—not lofty promises—are the ones capturing mindshare. No one’s impressed by another “AGI around the corner” whitepaper. They want a bigger context window, a cheaper API, or an edit that doesn’t break the build.

FAQ

Which LLM is best for writing code this week?
Claude for large-scale refactors and architecture. Cursor AI or Copilot for line-by-line autocomplete. DeepSeek if you need cheap API calls for batch code generation.

Is there a free ChatGPT alternative that’s actually good?
DeepSeek’s free chat is powerful and supports 128K context. Claude’s free tier is solid but rate-limited. Perplexity’s free search is useful for research, but it’s not a conversationalist.

What’s the cheapest AI API for a bootstrapped startup?
DeepSeek at $0.27/M input tokens. The next closest is GPT-5 Turbo at $0.50/M, but DeepSeek’s quality per dollar is currently unmatched for common tasks.

Should I cancel my ChatGPT Plus subscription?
Only if you don’t use the multimodal features heavily. For coding and research, Claude + Perplexity Pro is a formidable combo. For everyday image generation and voice, ChatGPT still leads.
