CallingBox is a YC-backed API that makes AI phone calls a one-liner. You configure a reusable agent with instructions, persona, and tools — then dispatch outbound or inbound calls via a single endpoint. The AI conducts the full conversation, then returns structured JSON matching whatever schema you defined. No managing telephony stacks, STT, TTS, or LLM pipelines separately. At $0.05 per connected minute all-inclusive — covering telephony, speech-to-text, language model, text-to-speech, and data extraction — it's substantially cheaper than stitching together LiveKit, Deepgram, GPT-4o, and ElevenLabs yourself (which their own benchmarks put at ~3x the cost). Sub-500ms latency with a 4.31 MOS quality score makes it production-ready. IVR navigation, voicemail detection, DTMF support, and MCP server integration cover the tricky edge cases that kill most voice implementations. Founded by Jonathan Chávez and Sebastian Crossa, the company offers $5 in free credits to get started. The use cases are obvious and immediate: appointment reminders, collections, customer support, multilingual outreach. For any team that's been putting off voice because of infrastructure complexity, CallingBox removes the excuse.

Cohere Command A is a 111-billion parameter large language model purpose-built for enterprise agentic workflows, including tool use, retrieval-augmented generation (RAG), and multi-step task execution. It features an expansive 256K token context window and is available through Cohere's API as well as on-premises deployment options for organizations with strict data sovereignty requirements. Command A is optimized for real-world enterprise automation rather than benchmark chasing, making it a serious contender for teams building production-grade AI agents.
Reviewer scorecard
“The single-endpoint design is exactly right — one call in, structured JSON out. MCP server integration means you can wire it to your existing agent tools without rebuilding. At $0.05/min I'd be crazy not to at least prototype with this.”
“A 256K context window combined with first-class tool use and RAG support is exactly what production agentic pipelines need — no more awkward workarounds. The on-prem deployment option is a genuine differentiator for enterprise devs stuck behind data compliance walls. Cohere clearly designed this for people actually shipping agents, not writing blog posts about them.”
“This space is already crowded with Bland AI, Retell AI, and Vapi — all of which have more mature ecosystems and enterprise track records. Vapi in particular has a similar price point and years of production deployments. CallingBox needs a clearer differentiator beyond 'one endpoint.'”
“Another massive parameter count dropped on us like it's a selling point — 111B means nothing if real-world latency and cost per call aren't competitive with GPT-4o or Claude 3.5. Cohere's enterprise-first positioning also means pricing opacity; 'contact us' licensing is a red flag for anyone trying to budget a real project. I'll believe the agentic claims when I see independent benchmarks, not a blog post from the vendor.”
“Voice is still the dominant communication channel for most of the world — banks, healthcare, governments. An API that commoditizes AI phone calls at $0.05/min will unlock workflows that no chat interface ever could. The 113-language potential alone is massive.”
“Command A signals a maturing AI industry — we're moving from 'impressive demos' to 'deployable enterprise infrastructure,' and Cohere is betting big on being the B2B backbone of the agentic era. The combination of on-prem availability, massive context, and multi-step reasoning puts this squarely in the stack of the next wave of autonomous enterprise systems. This is the kind of model that quietly powers a Fortune 500 transformation, and that's exactly where the real impact lives.”
“The structured JSON return is the killer feature from a product design perspective — it means you can embed AI calls in any workflow and get back data you can actually use. Podcasters, researchers, and community managers should all be paying attention.”
“Command A is clearly not built for creatives — it's an enterprise tool through and through, focused on workflow automation and data retrieval rather than imaginative generation. If you're hoping for a creative writing upgrade or design-adjacent AI, look elsewhere. That said, it could be genuinely useful for creators who need to build content pipelines at scale with structured data.”
