Mini toolsClaude Sonnet 4 Extended Thinking
By Anthropic
Model family: Claude
Extended Thinking takes the dependable Sonnet 4 model and gives it a larger reasoning budget. Instead of replying as soon as it finds a plausible path, it decomposes the problem, checks intermediate steps, and revises its plan before producing a final answer. The result is steadier performance on multi-step analysis, trickier proofs and derivations, repository-scale coding tasks, and long-form planning, with calmer error rates and more consistent logic. You keep the familiar Sonnet 4 interface—streaming, function calls, and schema-true JSON—so it drops straight into agent pipelines and retrieval-augmented apps. It also handles text and images in the same conversation, grounding explanations in charts, documents, and screenshots when needed. The trade-off is latency and token usage: Extended Thinking is slower and chattier under the hood, which is why teams often route routine queries to standard Sonnet and reserve this mode for moments when correctness matters most.

Overview
Claude Sonnet 4 (Extended Thinking) is the long-deliberation mode of Sonnet 4. It spends extra tokens “thinking” before answering, boosting accuracy on hard reasoning, math, and coding while keeping the same strengths—long context, tool/function calling, JSON outputs, and multimodal text-plus-image understanding.

They recently changed to a “point based system” where free users get 3000 daily point. Subscribers get 100,000,000 points monthly plus the 3000 daily. Each model has a wide range of costs. Some are cheap and some are more expensive. There is no longer unlimited messages for subscribers. It has since sparked an outrage among the community with many ending their subscriptions and moving away from Poe.

BotDojo is one of the most powerful AI Agent builders I've found out there. As a non-technical marketer, it took me a minute to get familiar with the designer, but using the preexisting templates is super helpful! I am now running outreach 100% on autopilot. BotDojo personalizes the copy for each contact we reach out to by email and LI. It also takes care of the drip campaign that I run through Lemilist. LOVE IT! I really hope to see more templates coming up soon!
