Public source research. Entries are sourced from vendor changelogs, documentation, announcements and press materials. Entries marked Partially Verified are reported by a credible source but not confirmed at the vendor's own materials, and should be independently verified before relying on them for procurement decisions.
Alta added GPT-6 Astra, Claude Fable 5.1, Claude Opus 5.5 and Gemini 3.8 Flash to its premium model list, selectable per step from a model picker under any prompt: email, LinkedIn, SMS and WhatsApp steps, AI conditions, AI enrichments, the call flow, the web assistant and Workflow AI actions. A campaign level Default AI model setting can also be applied to steps already built. Premium models are limited to Professional and Enterprise plans, and a premium model in AI enrichments uses more credits per row.
Buyers can see and choose which named third party model drafts each outbound touch, and the plan gating and higher enrichment credit cost decide which tier and budget a team needs to use them.

Common questions
How do I keep up with changes to go to market software?
Vendor release notes are the primary source and they are scattered, inconsistent and written to announce rather than to inform a buyer. The GTM Tech Index change log consolidates them into one feed with a fixed editorial policy. It tracks material product and capability changes at indexed go to market vendors: releases, AI and agent capabilities, integrations and interoperability, breaking API changes, pricing and packaging changes, and compliance and governance changes. It excludes funding rounds, valuations, stock listings, partnerships and awards, because none of those change what the product does. Every entry cites a live retrieved source, 100 percent of them today, and each is linked to the capability axis it bears on so a change can be read against the vendor's graded profile rather than in isolation. Entries confirmed at the vendor's own materials are marked Verified and the rest are marked Partially Verified, currently 189 and 61 respectively. The practical routine is to read the log for what changed and the weekly Brief for what it means.
Where do I find release notes for go to market software vendors?
Each vendor publishes its own, in its own format, on its own schedule, and many put them behind a login or retire them after a quarter. This page is the consolidated alternative: 250 tracked changes across 146 vendors so far, each carrying the source link back to the vendor's own release note, announcement or documentation. Recent entries cover Calendly, FirstTouch, FoxReach, HubSpot Sales Hub, ActiveCampaign, Aircall and others. The feed is filterable by vendor, change type, impact level and verification status, so a buyer tracking a shortlist can watch three vendors rather than reading everything. Where a vendor's own release notes exist publicly, the entry links straight to them.
What counts as a change worth tracking?
A change earns an entry if it would move a buyer's evaluation. That is a deliberately narrow test and it excludes most of what a vendor announces. Funding rounds, valuations, stock listings, partnerships and awards are out by policy: they tell you about the company rather than the product. Acquisitions qualify only where there is direct product impact. What is in: shipped capability, model and architecture changes, performance evidence, regulatory and licensure changes, security and compliance changes, integrations, pricing and packaging changes, safety and governance changes, and product sunsets. 250 entries have cleared that bar so far, across 10 change types, and 85 are graded High impact.
How is each entry verified?
Every entry requires a live retrieved source URL before it is written, and no entry exists without one. An entry marked Verified is confirmed in the vendor's own materials or a regulatory filing. An entry marked Partially Verified is reported by a credible third party but not confirmed at source, and should be independently checked before it is relied on in procurement. Vendor claims inside a summary are attributed to the vendor rather than restated as fact. Each entry also names the capability axis it bears on, which is what connects a change to the graded assessment on that vendor's profile rather than leaving it as news.
