Slow billing doesn't just create friction — it delays cash and compounds across every deal you close.Slow billing doesn't just create friction — it delays cash and compounds across every deal you close.

Most SaaS finance teams assume the gap between contract signature and first invoice is a minor inconvenience. The Tabs Billing Lag Calculator puts a dollar figure on it.

Answer 5 quick questions about your contracts, invoicing process, error rate, and DSO, and the calculator benchmarks your billing lag against top SaaS companies — then shows you exactly what it's costing you.

Two minutes. One number that's hard to ignore.

Getting the most out of advanced AI models like Anthropic’s Fable 5 isn’t about writing the perfect instruction. It’s about figuring out what you don’t know first. Anthropic developer Thariq Shihipar says the biggest bottleneck isn't the AI's capability anymore; it's our own blind spots. If you make a prompt too specific, the AI follows it right off a cliff. If you’re too vague, it gives you boring, generic filler.

The trick for the modern worker is using techniques like blindspot passes, structured interviews, and live notes to give the AI context, then letting it adapt. The emerging skill, he says, is contextual orchestration rather than command writing.

That philosophy is now extending into biotech. Anthropic has launched internal drug discovery programs targeting diseases traditional pharma firms avoid due to weak commercial incentives. Through its Claude Science platform, the company is using real-world laboratory experiments to train smarter models while transforming how biomedical research operates.

The operational speed is already apparent: Claude Science spotted viral contamination that went unnoticed by humans for a year and screened 100 rare genetic diseases in under an hour.

OpenAI is pushing a bigger idea than just better chatbots: a future where people barely use software interfaces at all. OpenAI cofounder Greg Brockman says AI agents should eventually handle tasks quietly in the background, without users constantly clicking through apps, menus, or workflows.

That vision is partly shaped by earlier failures. Brockman admitted ChatGPT Plugins struggled in 2023 because the models simply weren’t reliable enough to manage web tools and apps like Gmail on their own. Even now, AI systems still need heavy prompting, integrations, and human oversight, which is why OpenAI, Anthropic, and Microsoft all have dedicated teams helping companies deploy AI internally.

Meanwhile, the model race is speeding up again. Reports on 𝕏 suggest OpenAI could launch GPT-5.6 as early as July 7 with higher usage limits and stronger safeguards aimed at competing with Anthropic’s Fable 5 models. Sam Altman added to the hype this week, comparing GPT-5.6’s math breakthroughs to watching a child form words for the first time.

Mistral is making a bigger push into open-source AI with Leanstral 1.5, a model built for formal verification - the kind of math-heavy process used to prove software is actually correct. Instead of just generating code, Leanstral works inside the Lean 4 programming language to verify proofs, test logic, and catch errors before software ships.

The model scored 100 percent on the miniF2F math benchmark and solved 587 of 672 PutnamBench problems, which include difficult university-level competition math. Mistral also says Leanstral handled extremely long reasoning tasks spanning more than 2.7 million tokens during one proof exercise.

At the same time, Mistral CEO Arthur Mensch is using the release to argue against closed AI systems. He says proprietary AI providers gain deep visibility into customer workflows and internal data, while open models give companies more control over their infrastructure, model weights, and competitive knowledge.
