Promptfoo: Test Your LLM Prompts Like Unit Tests
Promptfoo is an open-source CLI (24.1k GitHub stars) that treats LLM prompts as testable code using YAML test cases and assertions. OpenAI announced it was acquiring the company on March 9, 2026, committing to continue the open-source project. This guide covers installation (Node.js 22.22.0 or newer, Node 24 recommended), scaffolding a first eval with npx promptfoo@latest init, choosing assertion types by cost tier, guarding cost and latency, RAG and agent evals, CI gating strategy, the red teaming half of the tool, and three honest limits of eval suites.

ChatCut: The AI Video Editor That Keeps Your Timeline Editable
ChatCut is an AI video editor that pairs an autonomous editing agent with a real, editable multi-track timeline, launched on Product Hunt in July 2026. Unlike one-click generators, it lets you prompt edits, then refine every cut manually, with XML export to Premiere or DaVinci. It bundles generation (Seedance 2.0, Kling 3.0, GPT Image 2, Nano Banana, ElevenLabs), uses credit-based pricing from a free tier, and its ChatGPT/Codex plugin lets editing run on your own tokens.

GPT-5.6: OpenAI's Sol, Terra, and Luna Go Public
OpenAI made its three-tier GPT-5.6 family (Sol, Terra, Luna) generally available on July 9, 2026 after government safety review. Pricing runs from Luna at $1/$6 to Sol at $5/$30 per 1M tokens, with a Sol Fast option at $12.50/$75 on Cerebras. The release adds Programmatic Tool Calling in the Responses API (63.5% fewer tokens, 50.1% fewer turns) and longer prompt caching, but Sol's 64.6% on SWE-Bench Pro still trails Claude Mythos 5 (80.3%).

GPT-Realtime-2.1: OpenAI Adds Reasoning to Its Voice API
On July 6, 2026, OpenAI released GPT-Realtime-2.1 and GPT-Realtime-2.1-mini for the Realtime API. The headline change is reasoning in the low-cost mini tier, plus a 25% cut in p95 latency from better caching. The mini holds the prior gpt-realtime-mini price (0 audio in, 0 audio out per 1M) while the full model runs 2/4. Reasoning effort is configurable from minimal to xhigh.

OpenAI Jalapeño: Custom AI Chip Aims to Beat Nvidia
OpenAI unveiled Jalapeño, its first custom inference chip co-designed with Broadcom on TSMC 3nm. Built in a nine-month design cycle, the reticle-sized ASIC targets roughly 50% lower inference cost than current Nvidia GPUs, with deployment starting late 2026 and Microsoft reportedly taking 40% of the first run for Azure.

GPT-5.6 Sol: OpenAI's Best Model, Held Back by Washington
On June 26, 2026, OpenAI previewed the GPT-5.6 series — Sol (flagship), Terra (balanced, 2x cheaper than GPT-5.5), and Luna (fastest, cheapest) — but restricted access to trusted partners at the US government's request due to the models' strong cybersecurity capabilities. OpenAI paired the release with its most robust layered safeguard stack and said it does not want government pre-release review to become the default.

Anthropic IPO: The $965B Filing That Beat OpenAI to Wall Street
On June 1, 2026, Anthropic confidentially filed a draft S-1 with the SEC at a roughly $965B valuation, backed by a $65B raise and a ~$47B May run-rate. OpenAI followed on June 8. Both target public listings as soon as fall 2026.

Prompt Caching: How to Cut LLM API Costs by Up to 90%
Prompt caching stores the computed KV attention tensors for a repeated prompt prefix so the model skips recomputation, cutting input cost and latency. Anthropic (explicit cache_control, ~90% read discount), OpenAI (automatic, 50% off, 1,024-token minimum), and Google Gemini (implicit plus explicit cache objects, up to 90%) all support it. The one rule that determines hit rate: put all static content at the front of the prompt and all dynamic content at the back.

ChatGPT Ads: Can Advertising and AI Trust Coexist?
On May 5, 2026, OpenAI opened a beta self-serve Ads Manager for ChatGPT with CPC bidding and aggregate measurement tools, backed by agencies like Dentsu, Omnicom, Publicis and WPP. OpenAI promises independent answers, private conversations and user control — but an AI assistant that answers in a single authoritative voice has more power to nudge than search ever did, making those principles essential to enforce.

AI Companion Chatbots: The 2026 Lawsuit Reckoning
A 2026 survey of the legal and regulatory reckoning facing AI companion chatbots. Florida sued OpenAI and Sam Altman on June 1, 2026; Character.AI settled teen-suicide suits and faces a Pennsylvania action; the FTC opened a companion-bot inquiry; and the EU AI Act becomes fully applicable on August 2, 2026, but leaves emotion-recognition gaps. The piece outlines what real safeguards would require.
